C language chapter-4. Escape sequence in c language.

Consider the following program.

Example-1

#include <stdio.h>

int main()

{

    printf("Hello world");

    printf("How are you?");

    return 0;

}

There are two printf statements. You may expect two lines of output. But the output is simply one line.

Output:

Hello worldHow are you?

Process returned 0 (0x0)   execution time : 0.016 s

Press any key to continue.

To make the output on two different lines you have to put ‘\n’ at the end of first printf statement.

Example-2

#include <stdio.h>

int main()

{

    printf("Hello world\n");

    printf("How are you?");

    return 0;

}

Output:

Hello world

How are you?

Process returned 0 (0x0)   execution time : 0.047 s

Press any key to continue.

‘\n’ is the type of escape sequence.it is called as new line escape sequence.

There are other escape sequences also.

‘\t’ is tab space escape sequence.

Example-3

#include <stdio.h>

int main()

{

    printf("Hello world\t");

    printf("How are you?");

    return 0;

}

Output:

Hello world     How are you?

Process returned 0 (0x0)   execution time : 0.047 s

Press any key to continue.

Instead of new line certain no of spaces are inserted at the output.

Like that two print a ‘\’ character on the output you have to type ‘\\’ in the program.

Also ‘\”’ is used to printf double quotes in the output:

And ‘\’’ is used to print single quote in the  output.

Thank you.
