Question
A C function attempts to find a substring. #include #include char* find_substring(char* haystack, char* needle) { if (haystack == NULL || needle == NUL
- L { return NULL; } return strstr(haystack, needle); } int main() { char* text = "Hello World"; char* pattern = NULL; // Potential bug here char* result = find_substring(text, pattern); if (result != NUL
- L { printf("Found: %s ", result); } else { printf("Not found or invalid input. "); } return 0; } What will be the output of this C program?
