Output of following program?
#include <stdio.h> int f1() { printf ("Geeks"); return 1;}
int f2() { printf ("Quiz"); return 1;}
int main()
{ int p = f1() + f2();
return 0;
} |
(A) GeeksQuiz
(B) QuizGeeks
(C) Compiler Dependent
(D) Compiler Error
Answer: (C)
Explanation: The operator ‘+’ doesn’t have a standard defined order of evaluation for its operands. Either f1() or f2() may be executed first. So a compiler may choose to output either “GeeksQuiz” or “QuizGeeks”.
