Write a C++ program that has three files: header, implementation, and main files. The

header file contains the following functions' prototypes:

1. void readArray(int a[], constint size)

This function reads the elements of the array from user.

2. void printArray(constint a[], const int size)

This function prints the elements of the array to the screen

3. int searchArray(constint a[], const int size, int number)

This function searches for a number in the array and returns its index (or -1 if not

found)

4. void multiplyByN(int a[], constint size, int element, int N)

This function searches for an element in the array and multiplies it by N.

Hint: Call searchArray() in order to find the index to the required element.

5. int sumEvens(constint a[], const int size)

This function calculates and returns the summation of all even numbers in the passed

array.

implementation.cpp file contains the definitions for the functions which their prototypes

are declared in header.h

In main.cpp:

Define local int array of size 10. Give values to its elements using an initializer

list.

Test your functions in the main program. A menu-driven program with the

following menu could be implemented for this purpose.

1. Read Array.

2. Print Array.

3. Multiply an element of the array by N.

4. Summation of all even numbers.

5. Exit.
