Chapter 3, Problem 1P

Explanation of Solution

Program code:

//include required header files

#include <iostream>

using namespace std;

//define the function main()

int main()

{

//declare the required variables

int r, c, a[100][100], b[100][100], sum[100][100], i, j;

//prompt the user to enter the number of rows

cout << "Enter number of rows (between 1 and 100): ";

//scan for the value

cin >> r;

//prompt the user to enter the number of colomns

cout << "Enter number of columns (between 1 and 100): ";

//scan for the value

cin >> c;

//prompt the user to enter the elements of the matrix

cout << endl << "Enter elements of 1st matrix: " << endl;

//iterate for loops

for(i = 0; i < r; ++i)

for(j = 0; j < c; ++j)

{

// Storing elements of first matrix entered by user.

cout << "Enter element a" << i + 1 << j + 1 << " : ";

        cin >> a[i][j];

}

//prompt the user to enter the elements of the matrix

cout << endl << "Enter elements of 2nd matrix: " << endl;

//iterate for loops

for(i = 0; i < r; ++i)

for(j = 0; j < c; ++j)

{

// Storing elements of second matrix entered by user.

cout << "Enter element b" << i + 1 << j + 1 << " : ";

cin >> b[i][j];

    }

// Adding Two matrices

//iterate for loops

for(i = 0; i < r; ++i)

for(j = 0; j < c; ++j)

//add the components

sum[i][j] = a[i][j] + b[i][j];

// Displaying the resultant sum matrix...
