...
This code can result in a divide-by-zero error during the division of the signed operands sl1 num1 and sl2 num2.
| Code Block | ||
|---|---|---|
| ||
long sl1num1, sl2num2, result; /* Initialize sl1num1 and sl2num2 */ result = sl1num1 / sl2num2; |
Compliant Solution
This compliant solution tests the suspect division operation to guarantee there is no possibility of divide-by-zero errors.
| Code Block | ||
|---|---|---|
| ||
long sl1num1, sl2num2, result; /* Initialize sl1num1 and sl2num2 */ if ((sl2num2 == 0)) { //* handle error condition */ } else { result = sl1num1 / sl2num2; } |
Modulo
The % operator provides the remainder when two operands of integer type are divided.

Risk Assessment
A divide-by-zero can result in abnormal program termination and denial of service.
