Comments can be singled-lined or multi-lined.

Single Line Comments

• Single-line comments are preceded by two forward slashes (/).
• Any information after the slashes / on the same line will be disregarded (not performed) because it is unparsable.

A single-line comment is used in this example.

#include <iostream>
 
int main()
{
    // This is a single line comment
    std::cout << "Hello World";
    return 0;
}

Multi-line comments

• A multi-line comment begins with /* and terminates with */.
• The compiler will discard any information between /* and */.

A multi-line comment is used in this example.

#include <iostream>
 
int main()
{
    /* This is a
    multi-line
    comment */
 
    std::cout << "Hello World";
    return 0;
}

Comments aid in code comprehension.

Every programming language has a specific way of commenting.

We utilise the!<!– content –> tag in HTML. Any text inserted between these brackets will be considered a comment.

“Ctrl + /” is the shortcut key. This will automatically add a comment on the content we’ve chosen.

Single comments and multiline comments are the two different categories of comments.

Single-line comments

Are those that are contained entirely within a single line.

<!– Single line Comment –>

Multi-line comments:

Comments that span multiple lines are referred to as multi-line comments.

<!–

This is a multiline comment.

You can add as many as lines you want.

You can use one or more lines for your comments.

Single line comment

• Beginning with two forward slashes (//), single-line comments.
• Any content on the same line that follows the slashes / will be disregarded (will not be executed).

#include <stdio.h>
int main()
{
    //This is a single line comment
    printf("Hello World!");
    return 0;
}

multi-line comments

• A comment with multiple lines begins with /* and finishes with */.
• The compiler will disregard any data between /* and */.

#include <stdio.h>
 
int main()
{
    /* This is a
    multi-line
    comment */
    printf("Hello World!");
    return 0;
}
