continue;

Question

why if we num -- after the continue ,we have infinited loop??

Answer 1

num==5
so num>0 is true
num==3 is false
We print 5 and we decrement num

So num==4
num>0 is true
num==3 is false
So we print 4 and we decrement num

Then num==3
num>0 is true
num ==3 is TRUE
continue is executed so we go to the while condition

num didn't change and it equal to 3

num>0 is true
num==3 is true so continue is executed

And it will repeat infinitely because num==3 and it will never change!!

Answer 2

blind magnet num is always 3 when you use continue , continue throws back the control to the start of while loop but since num never increments you get the condition checking if num==3 again till infinite times

Answer 3

#include <stdio.h>

int main() {
int num = 5;

while (num > 0) {

if (num == 3)
continue;

printf("%d\n", num);
num--;

}
}

why doesn`t this code work??

Answer 4

I don't understand what you mean. Can you explain in more details?
