Write a program to subtract two matrix.

Given a two matrix we have to calculate the subtract of two matrix and stored the result into a resultant matrix.

Subtraction of two matrix is same like we subtract two integer.C=A-B.

Example:

input:
10 9
8 7

3 4
5 6
output:
7 5
3 1 

Logic

add the value of first matrix of same row column to second matrix of same row column.

#include<bits/stdc++.h>
using namespace std;
int main() {
    int matrix1[10][10],matrix2[10][10] ,subtract[10][10];
    int row, col, i, j;
    cout<<"Enter rows and columns: "<<endl;
    cin>>row>>col;

    cout<<" Enter matrix1 elements:"<<endl;
    for (i = 0; i < row; ++i)
    {
        for (j = 0; j < col; ++j) 
        {
         cin>>matrix1[i][j];
        }
    }

 cout<<" Enter matrix2 elements:"<<endl;
  for (i = 0; i < row; ++i)
    {
        for (j = 0; j < col; ++j) 
        {
         cin>>matrix2[i][j];
        }
    }

   
    for (i = 0; i < row; ++i)
    {
        for (j = 0; j < col; ++j) {
         subtract[i][j] = matrix1[i][j]+matrix2[i][j];
        }
}
   
    cout<<"subtraction of the matrix:"<<endl;
    for (i = 0; i < col; ++i)
    {
        for (j = 0; j < row; ++j) {
            cout<<subtract[i][j]<<" ";
            if (j == row-1)
            {
                cout<<endl;
            }
     }   }
    
}

Output:

Enter rows and columns: 2 2
 Enter matrix1 elements: 10 9 8 9
 Enter matrix2 elements:5 6 7 8
subtraction of the matrix:
5 3 
1 1

Time Complexity=O(N*N)

Space Complexity=O(N*N);
