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.

- 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.

- The Issue: You have a function that accepts a variety of parameters. It is impractical to provide them as traditional parameters. So, what are you going to do?arrow_forwardA. Function calling another function You have already seen a function that has called another function, but you may not have paid close attention to it. In order to call a programmer-defined function inside another programmer-defined function, you need to have the declaration of the function that is being called before the declaration of the calling function. In this program you will write a function of void return type named compare that accepts an integer parameter named guess. This function will compare the value of guess with a seeded randomly generated integer between 1 to 100, inclusive, and let the user know what the random number was as well as whether the guess was larger than, smaller than or equal to the random number. NOTE THAT: You will NOT generate a random number inside the compare function. Rather, you will write another function named getRandom of int return type to do it. You will need to call getRandom from compare, no parameters are necessary. Inside your main…arrow_forwardThe terms parameter and argument can be used for the same thing: listed inside the parentheses in the function definition. An argument is the called Number of Arguments By default, a function must be called with the correct the function with 2 arguments, not more, and not that are passed into a function. A parameter is the that is sent to the function when it is Meaning the function expects 2 arguments, once the function calledarrow_forward

- . What is the difference between a function argument and a function parameter? Group of answer choices An argument is a variable that is created in a function to hold a value that has been sent to it and a parameter value is the value that a function returns to the calling routine. An argument is a value that is passed into a function and a parameter is variable that the function defines to hold value of the argument. An argument is a value that is passed into a function and a parameter is the value that a function returns to the calling routine. A parameter is a value that is passed into a function and an argument is the value that a function returns to the calling routine.arrow_forwardMark the following statements as true or false: To use a predefined function in a program, you need to know only the name of the function and how to use it. a. b. A value-returning function returns only one value. Parameters allow you to use different values each time the function is called. C.
