# Add two matrix in C++ by R4R Team

Matrix:
-Multidimensional Array
-Matrix consist of the rows and columns.

Syntax-
array[row][column]
//Matrix with numbers of rows and columns

Condition: order of both matrix must be same

Example-
a[2,3]={1,2,3,4,5,6}
b[2,3]={1,1,1,1,1,1}
Sum={2,3,4,5,6,7}

program:

#include< iostream>
int main()
{
int a[10][10],b[10][10],r1,c1,r2,c2,i,j;
cout<<"Enter rows and columns for Matrix_1"<< endl;
cin>>r1>>c1;
//input in matrix_1
cout<<"Enter "<< r1*c1<<" number in matrix_1"<< endl;
for(i=0;i< r1;i++)
{
for(j=0;j< c1;j++){
cin>>a[i][j];
}
}
cout<<"Enter rows and columns for Matrix_2"<< endl;
cin>>r2>>c2;
//input in matrix_2
cout<<"Enter "<< r2*c2<<" number in matrix_2"<< endl);
for(i=0;i< r2;i++)
{
for(j=0;j< c2;j++){
cin>>b[i][j];
}
}
if(r1==r2 && c1==c2)
{
cout<<"Result is:"<< endl;
for(i=0;i< r1;i++)
{
for(j=0;j< c1;j++)
{
cou<< a[i][j]+b[i][j]<<" ";
}
cout<< endl;
}
}
else
cout<<"Addition of these two matrix is not possible";
}

output-

Enter rows and columns in matrix_1
2 2
Enter 4 number in matrix_1
1 2 3 4
Enter rows and columns in matrix_2
2 2
Enter 4 number in matrix_2
4 3 2 1
Result
5 5
5 5

Enter rows and columns in matrix_1
2 2
Enter 4 number in matrix_1
1 2 3 4
Enter rows and columns in matrix_2
3 3
Enter 9 number in matrix_2
1 2 3 4 5 6 7 8 9
Addition of these two matrix is not possible
