#include <stdio.h>

unsigned int crc32(const char *str) {
    unsigned int crc = 0xFFFFFFFF;
    while (*str) {
        crc = (crc >> 8) ^ crc32_table[(crc ^ *str++) & 0xFF];
    }
    return crc ^ 0xFFFFFFFF;
}

int main() {
    printf("%08x\n", crc32("correct horse battery staple"));
    return 0;
}
And got the output: main.c: In function 'crc32': main.c:7:28: error: 'crc32_table' undeclared (first use in this function) 7 | crc = (crc >> 8) ^ crc32_table[(crc ^ *str++) & 0xFF]; | ^~~~~~~~~~~ main.c:7:28: note: each undeclared identifier is reported only once for each function it appears in main.sh: line 2: ./a.out: No such file or directory

Substring Evaluation

Testing if the previous output contains the string cb7e6e10: False
