That's my code... Is there anyway that in the first switch statement i could use both Char values and int values? if i wanted the user to enter either 1 or a 2 and they enter a z or an f or something, i would like it to prompt them again... but i can't figure it out... Thanks

Problem #1: switch(inst[50]) -- this command only checks the value at inst[50], which is the byte one past the end of the array inst. What are you trying to test here?

Problem #2: case 1: -- You entered characters, not integers, and this case is an integer value.

No. Since you don't have any integers, it doesn't matter.

if i wanted the user to enter either 1 or a 2 and they enter a z or an f or something, i would like it to prompt them again... but i can't figure it out...

You've already got it set up properly in the default case.

Your understanding of integer vs character needs to be fixed. If you are reading a character string ising cin.getline(inst, 50); , and you press the keys 2 5 1 enter, you did not enter the integer 251, you entered the characters '2', '5', and '1'.

I see this all the time, and I hope by me explaining it, will make it clear to you.

After creating an array like so: char buffer[10] = { 'a','b','c'}; when you use the operator[] ( [ # ] ) you are accessing a SINGLE ELEMENT. No matter how you try to twist the meaning of using the operator[] on a simple array, it always does the same thing.

This is accessing a SINGLE element of the array, and if I did this: std::cout << buffer[1]; it would access the second element of the array, the second character. It would print 'b'.

The operator[] is NOT magic.

Pointers may seem like magic, but they aren't either. In fact, when I learned to program and had the epiphany that nothing about the computer is magic I was also disappointed.

A C style string (sometimes called a C string) is an array of char's with the last character set to 0, or NULL, or '\0'. The program will process characters in a C string until the terminating NULL character is encountered, this avoids needing to specify the length/size of a string. Thus an algorithm can simply process characters until the character NULL is encountered. This is very important for large strings. Variable length strings are used. The string can occupy a part of, or all of (minus the NULL) a character array.

Pascal strings were limited by a value specifying the length, please see this wikipedia page for more information.
