I'm converting an array of integers into a char by iterating through the whole array, and then I'm adding the resulting string to ncurses's method new_item. For some reason I'm doing something wrong the way I reallocate memory, thus I get the the first column as:
-4 Choice 1 0 Choice 1
4 Choice 2 1 Choice 1
4 Choice 3 - Instead of - 2 Choice 1
4 Choice 4 3 Choice 1
4 Exit 4 Choice 1

// right here
char *convert = NULL;
for(i = 0; i < n_choices; ++i){
convert = (char *) realloc (convert, sizeof(char) * 4);
sprintf(convert, "%i", table[i]);
my_items[i] = new_item(convert, choices[i]);
}
my_items[n_choices] = (ITEM *)NULL;
my_menu = new_menu((ITEM **)my_items);
