C Operators

An operator is simply a symbol that is used to perform operations. There can be many types of operations like arithmetic, logical, bitwise, etc.

There are following types of operators to perform different types of operations in C language.

  • Arithmetic Operators
  • Relational Operators
  • Shift Operators
  • Logical Operators
  • Bitwise Operators
  • Ternary or Conditional Operators
  • Assignment Operator
  • Misc Operator

Comments in C

Comments in C language are used to provide information about lines of code. It is widely used for documenting code. There are 2 types of comments in the C language.

  1. Single Line Comments
  2. Multi-Line Comments

Single Line Comments

Single line comments are represented by double slash \\.

Mult Line Comments

Multi-Line comments are represented by slash asterisk \* ... *\. It can occupy many lines of code, but it can't be nested.


printf() and scanf() in C

The printf() and scanf() functions are used for input and output in C language. Both functions are inbuilt library functions, defined in stdio.h (header file).

printf() function

The printf() function is used for output. It prints the given statement to the console.

scanf() function

The scanf() function is used for input. It reads the input data from the console.


If statement in C

In the C programming language, the `if` statement is used for conditional execution of code. The basic syntax of the `if` statement is as follows:

```c
if (condition) {
    // code to be executed if the condition is true
}
```

Here, `condition` is an expression that evaluates to either true or false. If the condition is true, the code inside the curly braces will be executed. If the condition is false, the code inside the curly braces will be skipped.

Additionally, you can use an `else` clause to specify a block of code to be executed when the condition is false:

```c
if (condition) {
    // code to be executed if the condition is true
} else {
    // code to be executed if the condition is false
}
```

You can also use `else if` to specify multiple conditions:

```c
if (condition1) {
    // code to be executed if condition1 is true
} else if (condition2) {
    // code to be executed if condition2 is true
} else {
    // code to be executed if none of the conditions are true
}
```

Here, the conditions are evaluated in order, and the code block corresponding to the first true condition is executed.

Here's a simple example:

```c
#include <stdio.h>

int main() {
    int num = 10;

    if (num > 0) {
        printf("The number is positive.\n");
    } else if (num < 0) {
        printf("The number is negative.\n");
    } else {
        printf("The number is zero.\n");
    }

    return 0;
}
```

This program checks whether a given number is positive, negative, or zero and prints the corresponding message.

 what is c language

The C programming language is a general-purpose, procedural programming language developed by Dennis Ritchie at Bell Telephone Laboratories in 1972. C has had a profound influence on many other programming languages and is commonly used for developing system software, application software, and embedded systems.

Variables

In C, a variable is a named storage location in the computer's memory where you can store and manipulate data. Before using a variable in your program, you need to declare it, specifying its data type.

Data type

In C, data types are used to specify the type of data that a variable can store. Each variable in C must be declared with a specific data type, and the compiler uses this information to allocate the appropriate amount of memory and to interpret the data correctly. Here are some of the fundamental data types in C:

1. **int:**
   - Used for integer values.
   - Example: `int age = 25;`

2. **float:**
   - Used for single-precision floating-point values.
   - Example: `float pi = 3.14;`

3. **double:**
   - Used for double-precision floating-point values.
   - Example: `double price = 59.99;`

4. **char:**
   - Used for a single character.
   - Example: `char grade = 'A';`

5. **_Bool:**
   - Used for boolean values (0 or 1).
   - Example: `_Bool isTrue = 1;`

6. **short:**
   - Used for short integers.
   - Example: `short distance = 1000;`

7. **long:**
   - Used for long integers.
   - Example: `long population = 7000000000;`

8. **long long:**
   - Used for very long integers.
   - Example: `long long bigNumber = 9223372036854775807;`

9. **unsigned int:**
   - Used for integers that can't be negative.
   - Example: `unsigned int count = 10;`

10. **unsigned char:**
    - Used for characters without sign (0 to 255).
    - Example: `unsigned char asciiCode = 65;`

11. **unsigned long:**
    - Used for long integers that can't be negative.
    - Example: `unsigned long fileSize = 4294967295;`

12. **void:**
    - Represents the absence of a type. Used for functions that do not return a value or pointers that don't have a specific type.
    - Example: `void myFunction();`

These are the basic data types in C. It's essential to choose the appropriate data type based on the nature and range of the data you're working with to ensure efficient memory usage and accurate representation of values. Additionally, C allows for the creation of user-defined data types using structures and unions for more complex data organization.

Keywords

In C programming, keywords are reserved words that have specific meanings and functions in the language. These words cannot be used as identifiers (names for variables, functions, etc.) because they are already reserved for specific purposes. Here is a list of some of the keywords in the C programming language:

```c
auto      double     int       struct
break     else       long      switch
case      enum       register  typedef
char      extern     return    union
const     float      short     unsigned
continue  for        signed    void
default   goto       sizeof    volatile
do        if         static    while
```

Each of these keywords serves a specific purpose in the C language, and understanding their usage is crucial when writing C programs. Here's a brief explanation of some key categories:

- **Data Types:** `int`, `char`, `float`, `double`, `void`, etc.
- **Flow Control:** `if`, `else`, `switch`, `case`, `default`, `while`, `do`, `for`, `break`, `continue`, `goto`, etc.
- **Storage Classes:** `auto`, `extern`, `register`, `static`, etc.
- **Functions:** `return`, etc.
- **Structures and Unions:** `struct`, `union`, `typedef`, `enum`, etc.

It's important to note that these keywords are case-sensitive in C, so using uppercase or lowercase letters matters. For example, `int` is a keyword, but `Int` or `INT` are not.

In addition to these keywords, there are other identifiers that are reserved in certain contexts, such as library functions like `printf` and `scanf` from the standard input/output library (`<stdio.h>`), but they are not strictly keywords.

Using these keywords appropriately is essential for writing correct and understandable C programs.

Identifiers

In C programming, identifiers are names given to various program elements, such as variables, functions, arrays, etc. An identifier must adhere to certain rules and conventions. Here are the key rules for naming identifiers in C:

1. **Character Set:**
   - Identifiers can include letters (both uppercase and lowercase), digits, and underscores (`_`).
   - The first character must be a letter or an underscore.

2. **Case-Sensitivity:**
   - C is a case-sensitive language. For example, `myVariable` and `MyVariable` are treated as different identifiers.

3. **Reserved Words:**
   - Identifiers cannot be the same as C keywords or reserved words. For example, you cannot name a variable "int" or "while."

4. **Length:**
   - The length of an identifier is not fixed, but the compiler may have limitations. It's a good practice to keep identifiers reasonably short and descriptive.

5. **Examples:**
   - Valid Identifiers: `counter`, `my_variable`, `sum123`, `MAX_SIZE`
   - Invalid Identifiers: `123abc` (starts with a digit), `if` (reserved keyword), `my-variable` (contains invalid character `-`)

Examples of using identifiers in C:

```c
// Variable identifiers
int age;
float averageScore;

// Function identifier
void printMessage() {
    // function body
}

// Constant identifier
#define PI 3.14
```

In the example above:
- `age` and `averageScore` are variable identifiers.
- `printMessage` is a function identifier.
- `PI` is a constant identifier defined using the `#define` preprocessor directive.

Choosing meaningful and descriptive names for identifiers is crucial for writing readable and maintainable code. It helps in understanding the purpose of variables, functions, and other elements in your program.

Assemble a computer step by step

Assembling a computer can be a straightforward process if you follow the right steps and have the necessary components. Here's a simplified guide to assembling a computer in the simplest way:

**Components Needed:**
1. Central Processing Unit (CPU)
2. Motherboard
3. RAM (Random Access Memory)
4. Power Supply Unit (PSU)
5. Storage Drive (HDD or SSD)
6. Graphics Card (if not using integrated graphics)
7. Case
8. Cooling system (if required)
9. Monitor, keyboard, and mouse
10. Screwdriver
11. Anti-static wrist strap (optional but recommended)

**Step 1: Prepare Your Workspace**
Clear a clean and well-lit workspace. Work on a non-static surface (wooden or plastic table) if possible. Consider wearing an anti-static wrist strap to prevent static electricity from damaging components.

**Step 2: Install the CPU**
1. Open the CPU socket on the motherboard.
2. Align the CPU's notches with the socket's notches.
3. Gently lower the CPU into the socket.
4. Secure the CPU by latching down the socket lever.

**Step 3: Install RAM**
1. Open the RAM slots on the motherboard.
2. Align the notches on the RAM stick with the notches on the slot.
3. Press down firmly on both ends of the RAM stick until it clicks into place.
4. Repeat for additional RAM sticks (if applicable).

**Step 4: Install the Motherboard**
1. Place the motherboard in the case, aligning it with the standoffs.
2. Secure the motherboard to the case using screws.

**Step 5: Connect Power Supply**
1. Connect the PSU's main 24-pin ATX power connector to the motherboard.
2. Connect the CPU power connector (usually 4 or 8 pins) to the motherboard.
3. Connect any additional power cables needed for your components (e.g., GPU, storage drives).

**Step 6: Install Storage Drive**
1. Mount the storage drive (HDD or SSD) in a drive bay or slot in the case.
2. Connect data and power cables from the storage drive to the motherboard and PSU.

**Step 7: Install Graphics Card (if applicable)**
1. Insert the graphics card into a PCIe slot on the motherboard.
2. Secure the graphics card to the case using screws or brackets.
3. Connect any necessary power cables from the PSU to the graphics card.

**Step 8: Connect Cables**
1. Connect case cables (power button, LEDs, USB, audio) to the motherboard according to the motherboard's manual.
2. Connect monitor, keyboard, and mouse to appropriate ports.

**Step 9: Check Connections**
Double-check all connections to ensure everything is properly attached.

**Step 10: Close the Case**
Close the computer case and secure it with screws.

**Step 11: Power On**
Plug in the power cable and turn on the computer. If everything is connected correctly, it should boot up, and you can begin installing the operating system and drivers.

Remember to take your time, be patient, and consult the manuals for your components as needed. If you're unsure about any step, consider seeking assistance from a more experienced builder or a professional technician.
