How would I go about adding in the user input?

My C++ code compiles, but I realized after I finished that I need to make the user choose what row and column to get the row total, column total, highest in a row, and lowest in a row.

What do I change to add that into this code?

#include <iostream>

#include <string>

#define ROWS 4

#define COLS 5

using namespace std;

int getTotal(int[][COLS], int, int);

float getAverage(int[][COLS], int, int);

int getRowTotal(int[][COLS], int, int);

int getColumnTotal(int[][COLS], int, int);

int getHighestInRow(int[][COLS], int, int);

int getLowestInRow(int[][COLS], int, int);

int main()

{

int testArray[][COLS] =

{

{ 1, 2, 3, 4, 5 },

{ 6, 7, 8, 9, 10 },

{ 11, 12, 13, 14, 15 },

{ 16, 17, 18, 19, 20 }

};

cout << "The total of the array elements is "

<< getTotal(testArray, ROWS, COLS)

<< endl;

cout << "The average value of an element is "

<< getAverage(testArray, ROWS, COLS)

<< endl;

cout << "The total of row 0 is "

<< getRowTotal(testArray, 0, COLS)

<< endl;

cout << "The total of col 2 is "

<< getColumnTotal(testArray, 2, ROWS)

<< endl;

cout << "The highest value in row 2 is "

<< getHighestInRow(testArray, 2, COLS)

<< endl;

cout << "The lowest value in row 2 is "

<< getLowestInRow(testArray, 2, COLS)

<< endl;

return 0;

}

int getTotal(int array[][COLS], int rows, int cols)

{

int sum = 0;

for(int i = 0; i < rows; i++)

{

for(int j = 0; j < cols; j++)

{

sum = sum + array[i][j];

}

}

return sum;

}

float getAverage(int array[][C
