Is your keyboard broken? It looks like sticky key with (!), (,) and (?).
Do you know that ALL caps represents YELLING! Not cool! Stop yelling at people you don't even know.

Learn how to use a loop, and include the scanf() inside one.

Well, that because you used the scanf function to read the value. The quick solution for this is to place two getch or getchar()! Or you will have to call the following function just above the getch() function or everything you read a char you will have to call this function before you read. That makes sure that the input buffer is clear and program won't shutdown!
