Passing Arrays as a parameter to the Function || PF A

Passing Arrays as a parameter to the Function

Objective of this lab Manual is to get hands on experience of Passing Arrays as a parameter to the Function in C++. Get familiar with the syntax, Errors, and implementations.

Background: Passing Arrays as Function Parameters In C++, arrays are always passed by reference by default.  Whenever an array is passed as a parameter, its base address is sent to the called function. Generally, functions that work with arrays require 2 items of information as actual parameters: the beginning address of the array (in memory), and the number of elements to process in the array. For example (Function PrintArray): 

void PrintArray(int Array[], int ArraySize)

 {     for (int i = 0; i <= ArraySize - 1; i++)       

cout << "array[" << i << "] = "<< Array[i] << endl;

 }

Pre-lab: student should have implemented the Arrays and functions in C++.

The student must know how to

• Write functions and call them

• Trace and try to find output

Assessment tools:

The assessment is according to the student participation in the lab if the student solves the exercise, he will get the participation mark for this lab.

Lab Assignments:

Q1- write a program in C++ to take input in integer array and print the whole array’s values on the console using functions only?

Q2- write a program in C++ to take input in the array and check using Functions if there is negative value or not if negative value is found then your function should return true and if not then return false?

Q3- write a program in C++ to take input in character array using function and print on the console?

Q4- Write a program to take input in the array and create a function name find Vowels() which check the whole array and print the vowels founded in the array?

Q5- Write a program in C++ to take input in the double datatype array of any size and then pass it to the function and check for the values which is greater than 10 and print to on the console found or not found?

Q6- Write a program in C++ to swap to variable’s values using functions?

Note: should pass values to the functions using value by reference if failed to do so no marks will be awarded.

Q7- Write a program in C++ to change the value of a variable declared and initialized in the main function by using function named changeValue()?

Q8- Write a program in C++ to sum two variables using function named Sum()?

Q9- Write a program in C++ to solve the equation  using functions only?

Q10- Write a program in C++ to solve the Equation  using function and your function should not return anything and the result should print in the main function only?

Note: use value passing by reference.
