give me a c++ program to find the matrixes of order 2by2 & 3by3. and explanin its working.

2by2  Matrix

#include<stdio.h>

#include<conio.h>

void main(){
 
int arr1[10][10], arr2[10][10];
 
int arr3[][3]={
  
   {0,0,0},

   {0,0,0},

   {0,0,0}

   };

 int i, j;

 clrscr();

 printf("Enter 3x3 array 1:\n");

 for(i=0;i<3;i++){

  for(j=0;j<3;j++){

   printf("Enter element %d x %d:",i,j);

   scanf("%d",&arr1[i][j]);

  }

 }

 printf("Enter 3x3 array 2:\n");

 for(i=0;i<3;i++){

  for(j=0;j<3;j++){

   printf("Enter element %d x %d:",i,j);

   scanf("%d",&arr2[i][j]);

  }

 }

 for(i=0;i<3;i++){

  for(j=0;j<3;j++){

   arr3[i][j]=arr1[i][j] + arr2[i][j];

  }

 }

 printf("Addition of Array 1 and Array 2 is: \n");

 for(i=0;i<3;i++){

  for(j=0;j<3;j++){

   printf("\t%d",arr3[i][j]);

  }

  printf("\n");

 }

getch();

}

Output:

Enter 3x3 array 1:

Enter element 0 x 0:1
                                                         
Enter element 0 x 1:1 
                                                        
Enter element 0 x 2:1 
                                                        
Enter element 1 x 0:1
                                                         
Enter element 1 x 1:1   
                                                      
Enter element 1 x 2:1 
                                                        
Enter element 2 x 0:1 
                                                        
Enter element 2 x 1:1 
                                                        
Enter element 2 x 2:1    
                                                     
Enter 3x3 array 2: 
                                                           
Enter element 0 x 0:1 
                                                        
Enter element 0 x 1:1
                                                          
Enter element 0 x 2:1 
                                                        
Enter element 1 x 0:1  
                                                       
Enter element 1 x 1:1 
                                                        
Enter element 1 x 2:1 
                                                        
Enter element 2 x 0:1 
                                                        
Enter element 2 x 1:1   
                                                      
Enter element 2 x 2:1   
                                                      
Addition of Array 1 and Array 2 is:
 2       2       2
 2       2       2
 2       2       2
