What must come before using a variable in C?
Short answer. Declaring it: type, then name.
Does #define need a semicolon?
No, and no equals sign either.
Remember
| Type, name, then value |
| #define: no = and no ; |
In C, you cannot use a variable before declaring it. Write the type, then the name. R holds runs, forty five. PASS is a constant, thirty three. So it prints twelve. Type, name, then value. Hash define needs no equals and no semicolon.
