output of c prog

Question

#include<stdio.h>
int main(){
    int a;
    if(a=printf("hello"))
        printf("gatecse%d",a);       
}

Answer 1

In C, printf() returns the number of characters successfully written on the output .

  if(a=printf("hello"))//So here hello will print and return 5 which will assigned in a and condition evaluated true

  printf(“gatecse%d”,a);       //print gatecse and print the value of a

So output :hellogatecse5

Answer 2

Since printf() ----- returns the number of characters it prints and prints "hello"

so a=5

since if(a=5) ---- leads to true

statement gets printed as hellogatecse5
