Review

• Recall that a void-function is a C++ function that does not return a value

• Syntax: void fun_name(parameter_list);

• Return statements are optional in void-functions, are called without any argument, and are an exit point

  • they’re optional because there is an implicit return statement at the end of the function body just before the }

• It is an error to assign a variable to the result of calling a void-function
