Question

I am really lost on this question:

Write a code for a function which is given (as arguments) char *p (pointing to the start of the string), char c, and returns a char *q to the *second * occurrence of the character c in the string, or a NULL pointer if c is not found at least twice in the string.

Any help will be greatly appreciated.

Explanation / Answer

char* get_second(char *p, char c) { unsigned char num_found = 0; while (*p != '') { if (*p == c) { num_found++; } if (num_found >= 2) { return p; } ++p; } return 0; }
