copied!<p>I got 2 functions:<br/> - <code>stringCopy()</code> which copy the parameter <code>strToCopy</code> into another string dynamically allocated applying a sanitize (see 2nd function)<br/> - <code>_sanitized()</code> which returns a dynamically allocated uppercased version of the parameter and removing non-letters char (such as numeric values & spaces).</p> <p>Considering the following, I got an <code>EXC_BAD_ACCESS</code> because of <code>k</code> growing too much.</p> <pre><code>char* _sanitized(const char* str) { char* uppercasedStr = malloc(sizeof str); int k = 0; // Index de parcours de la chaîne originale int i = k; // Index dans la nouvelle chaîne char evaluatedChar; while ( (evaluatedChar = str[k]) != '\0') { if ('A' <= evaluatedChar && evaluatedChar <= 'Z') { uppercasedStr[i] = evaluatedChar; i++; } else if ('a' <= evaluatedChar && evaluatedChar <= 'z') { uppercasedStr[i] = evaluatedChar-32; i++; } k++; } i++; uppercasedStr[i] = '\0'; return uppercasedStr; } char* stringCopy(char* strToCopy) { char* uppercaseStr = _sanitized(strToCopy); char* copiedStr = malloc(sizeof uppercaseStr); int k = 0; while (uppercaseStr[k] != '\0') { copiedStr[k] = uppercaseStr[k]; k++; } k++; copiedStr[k] = '\0'; free(uppercaseStr); return copiedStr; } </code></pre> <p>I also noticed that when I copy char from <code>uppercaseStr</code> into <code>copiedStr</code> it modifies <code>uppercaseStr</code> in the same time which cause the overflow...</p>
