Submitted by Shamikh Faraz, on February 25, 2018

Consider the given example:

#include <stdio.h>

int main()
{

    printf("\t%d",printf("includehelp"));

    return (0);

}

Output

includehelp	11

It prints "includehelp 11". Word 'Includehelp' prints, because it is written under printf and but first printf is printing the number of letters counted in the word 'includehelp' i.e., so it is 'includehelp 11'.
