Exam 5: Functions for All Sub Tasks

The following is legal in a void function return;

A void function may not be used in an output statement.

What is the output of the following code fragments? Int trial int& a,int b) { Ifb > a) { A=b; Return -a; } Else { Return 0; } } Float x=0,y=10,z; Z=trialy,x); Cout << z << " " << x <<" " << y << endl;

In a function with call-by-reference parameters,the values of the actual arguments are passed to the function.

What type of value does a void function return? ____________

Given the function definition Void something int a,int& b ) { Int c; C = a + 2; A = a * 3; B = c + a; } What is the output of the following code fragment that invokes something? All variables are of type int.) R = 1; S = 2; T = 3; Somethingt,s); Cout << r << ' ' << s << ' ' << t << endl;

Functions can return at most one value.

Testing a function or program using test values that are at or near the values that change the outcome of the program is known as using

A simplified main program used to test functions is called

A simplified version of a function which is used to test the main program is called

If a function needs to modify more than one variable,it must

The values or variables listed in the function declaration are called _________ to the function.

If we want to test if a given function works correctly,we would write a _________ to test it.

A function that does not return a value is known as a ________ function.

What is the output of the following function and function call? Void calculateCostint count,float& subTotal,float& taxCost); Float tax = 0.0, SubTotal = 0.0; CalculateCost15,subTotal,tax); Cout << "The cost for 15 items is " << subtotal << ",and the tax for " << subTotal << " is " << tax << endl; //end of fragment Void calculateCostint count,float& subTotal,float& taxCost) { If count < 10) { SubTotal = count * 0.50; } Else { SubTotal = count * 0.20; } TaxCost = 0.1 * subTotal; }

In a function with call-by-reference parameters,any changes to the formal parameters will change the actual arguments passed to the function.

When a void function is called,it is known as

The variables passed a function are called _________.

If you write a function that should use call-by-reference,but forget to include the ampersand,

What is the correct way to call the following function? _________________________ void setDisplay);
