Would someone please explain me how having the same value VAL1
and VAL2
behave differently? For the first if
statement VAL1
is equal to zero? Thanks!
#include <stdio.h>
#define VAL1 (1U << 1) | (1U << 5)
#define VAL2 0x22
int main()
{
printf("VAL1: %d\r\n", VAL1);
printf("VAL2: %d\r\n", VAL2);
if (VAL1 == 0)
{
printf("TRUE 1\r\n");
}
if (VAL2 == 0)
{
printf("TRUE 2\r\n");
}
if (VAL1 == VAL2)
{
printf("TRUE 3\r\n");
}
}
Output:
VAL1: 34
VAL2: 34
TRUE 1
TRUE 3
