Demo Examples

Integer Underflow (Wrap or Wraparound)

CWE-191

The following example subtracts from a 32 bit signed integer.


               
}
return 0;

The example has an integer underflow. The value of i is already at the lowest negative value possible, so after subtracting 1, the new value of i is 2147483647.
