Chapter 3.4, Problem 3.18CP
Explanation of Solution
Difference between pass by value and pass by reference:
| Pass by value | Pass by reference: |
|
A copy of the argument’s value which is passed into the parameter variable is referred as pass by value. |
Pass by reference allows the argument to passed into a special type of parameter called reference variable. |
|
In the pass by value, the called module creates new variables to store the value of the arguments passed to it. |
The reference variables permit the module to access the original argument of the parameter. |
|
The changes made in the formal parameters do not reflect on the actual parameters... |

Students have asked these similar questions
Static Variable: a variable whose lifetime is the lifetime of the program (static int x;)
Dynamic Variable: It is a pointer to a variable (int *x;)
Is this comparison true?
If an argument is given into a reference parameter, it will be treated as if it were a reference parameter.
What is the difference between a reference and a pointer?

- C++ beginnerarrow_forwardLowest Score Drop Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100.arrow_forward# Python 3 def printFunction(num1, num2): num3 = num1 + num2 return num3print(num3) Explanation: Here, num3 is the local variable that is defined in the scope of the function and when it is used outside the function, an error occurs. Print(num3) is the statement which is outside the scope of the function. So, when this statement is executed, there is no variable named num3 to be printed, so it gives an error. The error that occurs is : NameError: name 'num3' is not defined Construct a function that takes an argument. Give the function parameter a unique name. Show what happens when you try to use that parameter name outside the function. Explain the results. Show what happens when a variable defined outside a function has the same name as a local variable inside a function. Explain what happens to the value of each variable as the program runs.arrow_forward
- Please help me in c++ languagearrow_forwardIn C/C++, True or False: A function that changes the value of a variable passed by reference also changes the value of the original variable. A variable's type helps define the amount of memory it takes to hold a value of that type.arrow_forwardpointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.arrow_forward
