when i compile the program, the avg is displaying a garbage value (-1.#J) because i did 0/0 which is an error. So my question is how can i fix this. Also, when i want to input a string character how can i make the program to read the whole string character. For example if i type in (ghjk) it should be not valid. But instead its reading (g). Also, my program is reading a negative value how can i stop that it should say "inproper input".
