Question

Output of the following program?

#include<stdio.h>
struct st 
{ 
    int x; 
    struct st next; 
}; 
int main() 
{ 
    struct st temp; 
    temp.x=10; 
    temp.next=temp;
    printf("%d",temp.next,x); 
    return 0; 
}

• A. Compiler Error
• B. $10$
• C. Runtime Error
• D. Garbage Value

Answer 1

COMPILER ERROR , Here compiler doesnt found exact type of next, it behaves like recursion

Answer 2

struct st next;

This should be a pointer to a struct. A Struct object cannot be inside the struct definition. So this compiler error will be detected first.
