PLEASE SOLVE THIS QUESTION WITHOUT CHANGING THE SOURCE CODE POSTED BELOW. (ONLY ADDING)

#include <iostream>

using namespace std;

const int arrSize = 3;

// QUESTION ii. COMPLETE A displayMatrix(...) FUNCTION HERE

// QUESTION iii. COMPLETE A transposedMatrix(...) FUNCTION HERE

// QUESTION iv. COMPLETE A calculateTotal(...) FUNCTION HERE

int main(){

// variable declaration

int mat[arrSize][arrSize], transMat[arrSize][arrSize] = {0}, total = 0;

// QUESTION i. Prompt user to enter 9 integer numbers and fill in into the matrix

cout << "\nThe original matrix is : \n";

displayMatrix(mat, arrSize); // function called to display matrix

// function called to transpose matrix

transposedMatrix(mat, transMat, arrSize);

cout << "\nThe transposed matrix is : \n";

displayMatrix(transMat, arrSize); // function called to display matrix

calculateTotal(mat, arrSize, total); // function called to calculate total

cout << "\nThe total of the matrix is " << total << endl;

return 0;
