Example 1
\\ is used to escape a backslash character. The first \ is the
escape character and the second \ is the real character we would
like to output.
#include <stdio.h>
int main()//from w ww . j av a 2s . c o m
{
printf(" \\ string.");
return 0;
}
The code above generates the following result.
Example 2
We can escape a single quote with \'.
#include<stdio.h>
/*from w w w.ja v a2s . c o m*/
int main(void)
{
printf("If at first you don\'t succeed, try, try, try again!");
return 0;
}
The code above generates the following result.
Example 3
Add new line character
#include <stdio.h>
//from w w w .j a v a 2 s . c o m
int main(void)
{
printf("A\nB\nC");
return 0;
}
The code above generates the following result.
Example 4

#include <stdio.h>
//from www . j a v a2 s. com
int main(void)
{
printf("\n\"It is a wise father that knows his own child.\" Shakespeare");
return 0;
