C #include <stdio.h> int main() { int i = 1024; for (; i; i >>= 1) printf("GeeksQuiz"); return 0; } How many times will GeeksQuiz be printed in the above program?

The program will show compile-time error

C #include <stdio.h> int i; int main() { if (i) { // Do nothing } else { printf("Else"); } return 0; } What is correct about the above program?

It is unpredictable as i is not initialized.
