Code examples

The following code example fails the check and will give a warning:

#if __cplusplus
  #include <cstdlib>
	#include <cstdio>
#else
  #include <stdlib.h>
#endif

void example(void) {
	if (!rand()) {
		printf("The first random number is 0");
	} else if (!rand()) {
		printf("The second random number is 0");
	}
}

The following code example passes the check and will not give a warning about this issue:

#if __cplusplus
	#include <cstdlib>
	#include <cstdio>
#else
	#include <stdlib.h>
#endif

void example(void) {
	if (!rand()) {
		printf("The first random number is 0");
	} else if (!rand()) {
		printf("The second random number is 0");
	} else {
		printf("Neither random number was 0");
	}
}
