Here you will get a C++ program to find the addition of two matrices. We can add two matrices only if they have similar dimensions.
For example:
Matrix A:
3 7
2 5
Matrix B:
5 6
1 4
The addition of A and B is:
8 13
3 9
Let us see the code for matrix addition in C++.

Output:
Enter no. of rows and columns of matrix A:2
2
Enter no. of rows and columns of matrix B:2
2
Enter matrix A row wise:2 2
3 3
Matrix A:
2 2
3 3
Enter Matrix B row wise:2 2
3 3
Matrix B:
2 2
3 3
Sum of Matrices A and B:
4 4
6 6
