Code Block

bgColor	#ccccff

int value;

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

Compliant Solution

Using bitwise operators is safe on unsigned integers:

Code Block

bgColor	#ccccff
language	c

unsigned int value;

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

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