How many times will “Hello!” be printed in the program ?

Question

#include <stdio.h> int main() {int I = 1024; for (; I; I >>= 1) printf ("Hello!"); return 0;}?

Answer 1

The string Hello! will be printed 11 times.

Based on the code provided, the code will execute while the variable I is a non-zero positive integer. The for loop updates the value of the variable I with a new value that is the right shift value of I by 1 position.

Decimal: 1024>512>256>128>64>32>16>8>4>2>1

Binary: 10,000,000,000>1,000,000,000>100,000,000>10,000,000>1,000,000>100,000>10,000>1,000>100>10>1>0(Stopping condition).

Thus running the for loop for 11 times.
