Example:

int x = 5;
int y = 10;
/*
    The following code calculates the sum of two numbers.
    It takes two integers, x and y, as input and returns their sum.
*/
int sum = x + y;

Explanation:

Multi-line comments are often used to provide detailed explanations for code blocks or functions.
In this example, the comment provides an explanation of the code that calculates the sum of two numbers.

Example:

/*
    This is the outer comment.
    /* This is a nested comment. */
    It is ignored as well.
*/

Explanation:

C allows nesting of multi-line comments.
In this example, an inner multi-line comment /* This is a nested comment. */ is placed within the outer comment.
The compiler ignores both the outer and inner comments.

Example:

int age = 25;
/*
if (age >= 18) {
    printf("You are an adult!\n");
    // Handle adult-related actions here
} else {
    printf("You are a minor.\n");
    // Handle minor-related actions here
}
*/

Explanation:

Multi-line comments can be used to temporarily disable a block of code within the code.
In this example, the block of code inside the if and else blocks is commented out, so it won't be executed.
This can be useful for debugging or testing different code paths without deleting the code.

Example:

/*
int x = 10;
int y = 20;
int z = x + y;
*/

Explanation:

Multi-line comments are often used to comment out a block of code.
In this example, the block of code between /* and */ is commented out and won't be compiled or executed.
This can be helpful when temporarily disabling a section of code during testing or debugging.

Description:

In C, multi-line comments (also known as block comments) allow you to add comments that span multiple lines. Multi-line comments begin with /* and end with */. Anything between /* and */ is considered a comment and is ignored by the compiler.

Example:

/*
    This is a multi-line comment.
    It can span multiple lines and is ignored by the compiler.
    It is used for adding detailed explanations or large comment blocks.
*/

Explanation:

In this example, the multi-line comment starts with /*.
The comment content can span multiple lines.
The comment is terminated with */.
Anything between /* and */ is considered a comment and is not processed by the compiler.

Example:

int x = 10; // Initialize x to 10
int y = 20; // Initialize y to 20
// int z = x + y; // This line is commented out

Explanation:

Single-line comments can be used to comment out a portion of a line, rather than the entire line.
In this example, the third line is partially commented out to exclude the calculation of z.

Example:

int age = 25;
if (age >= 18) {
    printf("You are an adult!\n");
    // Handle adult-related actions here
} else {
    printf("You are a minor.\n");
    // Handle minor-related actions here
}

Explanation:

Single-line comments can be used within the code to provide additional details about specific sections.
In this example, the comments inside the if and else blocks explain that different actions can be handled based on the age of the person.

Example:

int result = add(5, 10); // Call the add function with arguments 5 and 10

Explanation:

Single-line comments can be placed after code statements to provide explanations or reminders for the purpose of that code.
In this example, the comment explains the purpose of the code and what the function call does.

Example:

int x = 10; // Initialize the value of x to 10
// int y = 20; // This line is commented out and won't be executed

Explanation:

Single-line comments are often used to comment out lines of code that are not needed at the moment.
In this example, the second line (int y = 20 is commented out, so it won't be compiled or executed.
Developers use this technique for temporarily disabling code without deleting it, which can be useful during testing or debugging.

In C, single-line comments are used to add explanatory notes or comments to the code that are ignored by the compiler. They begin with the double forward slash // and continue until the end of the line.

Example: Basic Single-Line Comment

// This is a single-line comment

Explanation:

In this example, the single-line comment starts with //.
Anything after // on the same line is considered a comment and is ignored by the compiler.
This comment serves as a simple explanatory note for the code.
