Question

Write a C++ program to demonstrate exception handling by using matrix multiplication
operation. Matrix multiplication function should notify if the order of the matrix is invalid, using exception.

Answer 1

Answer:

#include<iostream>

#include<conio.h>

#include<process.h>

#include<exception>

using namespace std;

void matsum()

{

int m, n, i, j, first[10][10], second[10][10], sum[10][10];

try

{

cout << "Enter the number of rows and columns of matrix ";

cin >> m >> n;

cout << "Enter the elements of first matrix\n";

if (m>10 || n>10)

//exit(0);

throw 1;

}

catch(int)

{

cout<<"subscript invalid";

}

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

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

cin >> first[i][j];

cout << "Enter the elements of second matrix\n";

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

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

cin >> second[i][j];

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

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

sum[i][j] = first[i][j] + second[i][j];

cout << "Sum of entered matrices:-\n";

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

{

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

cout << sum[i][j] << "\t";

cout << endl;

}

}

int main(void)

{

matsum();

getch();

}
