Instead of `char newWord[length + 1];` you could have used `char newWord = malloc((length + 1) sizeof(char));`, but the `newWord[length] = '\0';` is critical, and so is having the space for this null terminator (the `+1`). And in your code, you forgot to `free(newWord);` before `return`ing, that's the memory leak, which is trivially fixed by using an array instead of `malloc`.

However, I don't think I quite understand... do you mind elaborating more? This is my original code: `int length = strlen(word); char newWord = malloc(length sizeof(char));` and this is what I changed it to: `int length = strlen(word); char newWord[length + 1]; newWord[length] = '\0';`
