Question
Chapter 5.2, Problem 12STE
Program Plan Intro
void Functions:
- A function must either return a single or no value.
- A function where no value is returned is termed as “void” function.
- The “void” function is been defined in same way as function that would return a value.
- It implements only subtask for complete problem.
- If a “void” function is called, formal parameters are substituted with arguments.
- The statements in function body are executed.
- The “return” statement specifies value that is been returned.
Call-by-Reference:
- It is a method for substituting arguments.
- The argument is substituted for formal parameter.
- The function call arguments may be a variable.
- This argument variable is substituted for formal parameter.
- It is similar to copying of argument variables into function definition body in place of formal parameter.
- The function body code is been executed once argument is substituted.
- This code can change argument variable value.
- The ampersand sign (&) is attached to end of type name in formal parameter list in both function declaration as well as function header definition.
Call-by-value:
- It copies actual value of an argument into function’s formal parameter.
- The changes made to parameter inside function have no effect on argument.
- This technique is used in default in programs.
- The code within a function could not alter arguments that are used for calling function.

Group of answer choices
A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call.
The parameter is the passed value.
A function’s parameter is referred to as the formal parameter to distinguish it from the value that is passed in during the function call.
The argument is the passed value.
A function’s parameter is used for passing by reference.
The argument is used for passing by value.
A function’s parameter is used for passing by value.
The argument is used for passing by reference.
They are identical but using different terms.
in c++, "Overload of functions"
Write an overloaded function that returns a value based on a set of formal parameters: .
z={ x - a;
x + a - b
