Return type for printf

The printf() returns the number of characters sent to the standard output device……

<code>

#include<stdio.h>
main()
{
int i;
int a = 10;
printf(“%d”,a);
printf(“%d”,printf(“%d%d%d”,a,a,a));
}

</code>

OUTPUT:

10 10 10 6

EXPLANATION :

The inner printf function gets executed first and prints 10 10 10.Then the outer function is executed which returns 6 because of the 3 10s that are printed which is equal to 6 characters
