Return Values
Functions return a value or return void. Void is a signal to the compiler that no value will be returned or NULL.
To return a value from a function, write the keyword return followed by the statement you want to return. It can be a number, but most of the time it will be an expression. For example:
 | | | | |
return 8;
return (Num1 + Num2);
return (function()); |
| |
|
These are all working return statements When the return keyword is encountered, the expression following return is returned as the value of the function. Program execution returns immediately to the calling function, and any statements following the return are not executed.
