Question

Given that arrayIntValues [MAX_ROWS][MAX_COLUMNS] is a 2 dimensional array of positive integers, write a C++ function howManyEven to find the total number of even elements in the array. It should have input parameter array arrayIntValues. The function should return an integer.

Answer 1

Follows are the method definition to this question:

int even(int A[MAX_ROWS][MAX_COLUMNS], int length,int width)//defining a method even,that accept 2D array and two integer variables

{

int E_num = 0;//defining an integer variable E_num that holds a vlue 0

for (int i = 0; i < length; ++i)//declare for loop for row count

{

for (int j = 0; j < width; ++j)//declare for loop for column count

{

if(A[i][j]%2 == 0 )//use if block that check even number in array

{

E_num++;//incrementing the value of E_num

}

}

}

return E_num;//return E_num value

}

Step-by-step explanation:

In the above code, a method "even" is defined, which accepts a 2D array "A" and two integers " length and width" in its parameter.

Inside the method, an integer variable "E_num" is defined that uses two for loop and an if block for the count the even numbers which are available on the 2D array.
