INT18-C. Evaluate integer expressions in a larger size before comparing or assigning to that size. If an integer expression involving an operation is compared to or assigned to a larger integer size, that integer expression should be evaluated in that larger size by explicitly casting one of the operands. See more This code example is noncompliant on systems where size_t is an unsigned 32-bit value and long long is a 64-bit value. In this example, the programmer tests for wrapping by … See more Failure to cast integers before comparing or assigning them to a larger integer size can result in software vulnerabilitiesthat can allow the execution of arbitrary code by an attacker with … See more In this compliant solution, the length operand is upcast to unsigned long long, ensuring that the addition takes place in this size: This test for wrapping is effective only when the sizeof(unsigned long long) > sizeof(size_t).
