Question

write a c++ program to add two matrices

Answer 1

#include <iostream> using namespace std; int main() { int r, c, a[100][100], b[100][100], sum[100][100], i, j; cout << "Enter number of rows (between 1 and 100): "; cin >> r; cout << "Enter number of columns (between 1 and 100): "; cin >> c; cout << endl << "Enter elements of 1st matrix: " << endl; // Storing elements of first matrix entered by user. for(i = 0; i < r; ++i) for(j = 0; j < c; ++j) { cout << "Enter element a" << i + 1 << j + 1 << " : "; cin >> a[i][j]; } // Storing elements of second matrix entered by user. cout << endl << "Enter elements of 2nd matrix: " << endl; for(i = 0; i < r; ++i) for(j = 0; j < c; ++j) { cout << "Enter element b" << i + 1 << j + 1 << " : "; cin >> b[i][j]; } // Adding Two matrices for(i = 0; i < r; ++i) for(j = 0; j < c; ++j) sum[i][j] = a[i][j] + b[i][j];
