Discussion Forum : Functions - Find Output of Program (Q.No. 11)
11.
What will be the output of the program?
#include<stdio.h>
int main()
{
int i=1;
if(!i)
printf("IndiaBIX,");
else
{
i=0;
printf("C-Program");
main();
}
return 0;
}
Answer: Option
Explanation:
Step 1: int i=1; The variable i is declared as an integer type and initialized to 1(one).
Step 2: if(!i) Here the !(NOT) operator reverts the i value 1 to 0. Hence the if(0) condition fails. So it goes to else part.
Step 3: else { i=0; In the else part variable i is assigned to value 0(zero).
Step 4: printf("C-Program"); It prints the "C-program".
Step 5: main(); Here we are calling the main() function.
After calling the function, the program repeats from step 1 to step 5 infinitely.
Hence it prints "C-Program" infinitely.

Prints infinitely until stckoverflow occurs.

What about the stack overflow concept?

Instead of if (!i) we use if (i) then what will be the output of program.

This program not run because after if { bracket is not given.

@Ruchi.
If (not 5) is false because it's 5 hence else is executed and prints C-program infinitely because it's the similar case.

@Saikrishna.
Inside else main is called again, it means the program starts from starting hence prints C-program infinitely. Whenever, the main function is called i initializes to 1 always in this program.

After recalling the main, the value of I is not changed why. In the else part I is initialized with 0.
So calling main part I is to be reinitialized with 0. It is my doubt.
