Code Block

bgColor	#ffcccc
lang	c

int value;

if (scanf("%d", &value) == 1) {
  if (value & 0x1 != 0) {
    /* Do something if value is odd. */
  }
}

Compliant Solution

The same thing can be achieved compliantly using the modulo operator:

Code Block

bgColor	#ccccff
lang	c

int value;

if (scanf("%d", &value) == 1) {
  if (value % 2 != 0) {
    /* Do something if value is odd. */
  }
}

Incorrect assumptions about integer representation can lead to execution of unintended code branches and other unexpected behavior.
