Understanding infinite loop with while loop

Question

#include <stdio.h>
#include <cs50.h>
int main(void)
{
int h;
h=get_int("h ");
while (h>2){
printf ("ffff");
}
}

As any integer greater than 2 entered, there is an infinite loop (ffff printed infinitely). Could anyone please explain why so.

Answer 1

while() will run as long as the condition inside is true. In your code, an integer >2 will make it an infinite loop because the condition will be forever true.

Alternatively, if you use if() instead of while(), it will print "ffff" once.
