This compliant solution uses different, more descriptive variable names. Also it uses strcpy_s.
| Code Block | ||
|---|---|---|
| ||
char error_msg[100];
void hello_message() {
char hello_msg[80] = "Hello";
errno_t e = strcpy_s(error_msg, 100, "Error");
/* .. handle e - the value returned by strcpy_s */
}
