Have you ever used a calculator before? Remember the ANS button?

Basically variables store information so that you can use them in other places, check their values, and execute other functions based on that value.

char holds a char value. Other variables depend on their types. But i'm not sure what you're confused about here

int = number value, but it's short, so it's maximum isn't very large in comparison to a long int.
char = one character value

That's it, what is the char exactly used for in a program, to understand what someone puts in???
