#include<stdio.h>

int main(){

int c=5;

printf("%d %d %d ",c,c<<2,c>>2);

}

`<<`

is bit shift operation, if you do not know binary numbers, you can assume, that <<1 multiplies number by 2, <<2 multiplies value by 4, << 3 by 8 (2^3) and so onâ€¦

`5 << 2 = 5 * 4 = 20`

1 Like

n << b means n*(2^b)

n >> b means n/(2^b)

only valid for integer type only.

its output :

5 20 1
