将字符串拆分为单词数组

Question

I am working on a C function to split a string of letters into an array, however it keeps seg faulting and I have no idea why.

I have run it through DDD a few times, it was not of much help.

char* stringToArray(const char *desc)
{
    int i = 0;
    int j = 0;
    char *array[5][10] = {{0}};/*5 words, 10 chars each*/

    while (desc[i] != '\0')
    {
        if (desc[i] != ' ') {
            *array[j][i] = desc[i]; /*seg faults here*/
        }

        else {
            j++;
        }
        i++;
    }
    return **array;
}

Any help would be greatly appreciated Thanks.

You will need to make your array static or allocate some memory for it - returning a pointer to a local array won't work.

You also might want to check out strtok.
