Code examples

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

/* string */
const char *s1 = "\x32x";
const char *s2 = "\122x";

/* wide char */
int w1 = '\122n';
int w2 = '\x32n';

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

/* string */
const char *s1 = "\x32" "n";
const char *s2 = "\122" "n";
const char *s3 = "\x32\x33";
const char *s4 = "\122\123";

/* wide char */
int w1 = '\122\n';
int w2 = '\x32\n';

/* char */
unsigned char c1 = '\x32';
unsigned char c2 = '\122';
