Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
(Practice) For the following function headers, determine the number, type, and order (sequence) of values that should be passed to the function when it’s called and the data type of the value the function returns: a. int factorial(int n) b. double volts(int res, double induct, double cap) c. double power(int type, double induct, double cap) d. char flag(char type, float current, float time) e. int total(float amount, float rate) f. float roi(int a, int b, char c, char d, float e, float f) g. void getVal(int item, int iter, char decflag, char delim)
Which of the following is not a step in the function-calling process?a) The calling program suspends.b) The formal parameters are assigned the value of the actual parameters.c) The body of the function executes.d) Control returns to the point just before the function was called.
Which of the following is false?a. A function can receive information either by value or by reference.b. When a function ends, any variables listed in the function’s parameterList can be used by the statement that invoked the function.c. The variables listed in a function’s parameterList have procedure scope.d. A function uses the Return statement to return a value to the statement that invoked it.
Which statement of the following is the most appropriate? Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.

The first argument will be the default argument.C. The middle argument will be the default argument.D. All the argument will be the default argument.
To determine whether a variable is being passed to a function by value or by reference, you will need to examine_________ .a. the statement that invoked the functionb. the function headerc. the statements entered in the functiond. either a or b
what if you want to call global variable with same name as local inside a function? Use global keyword to express code.
Give the function header for each of the following: a) Function change that takes two double arguments a and b and returns a double. b) Function largest that takes three integers, x, y and z, and returns an integer. c) Function display that does not receive any arguments and does not return a value. How do you call the function display?
2. If a function have all the default arguments but still some values are passed to the function then _________.

What statement about the print() function is true? A. print() has a variable number of parameters. B. print() can have only one parameter. C. print() can be used to obtain values from the keyboard. D. print() does not automatically add a line break to the display. After a function calculates a value, how does it return that value to main program where it was called? A. By including that value in a return statement. B. By using the print() function C. By storing the value in a local variable. D. Since function variables are destroyed when the function call is completed, the calculated values are destroyed as well. Where in a program should a function be defined? A. At the very end B. Immediately after the first call to the function C. Near the top of the program D. Functions do not have to be defined to be used
