C Program to Demonstrate Nested Printf Statements

nested Printf statements : Example 1

#include<stdio.h>
#include<conio.h>

void main() {
   clrscr();
   printf("%d", printf("abcdefghijklmnopqrstuvwxyz"));
   getch();
}

#include<stdio.h>

#include<conio.h>

void main() {

clrscr();

printf("%d", printf("abcdefghijklmnopqrstuvwxyz"));

getch();

}

Output :

abcdefghijklmnopqrstuvwxyz26

1	abcdefghijklmnopqrstuvwxyz26

How ?

“abcdefghijklmnopqrstuvwxyz” will be first Printed while executing inner printf
Total Length of the “abcdefghijklmnopqrstuvwxyz” is 26
So printf will return total length of string
It returns 26 to outer printf
This outer printf will print 26
