In this program, we have defined a function
addMatrices that takes two 2D integer arrays
m1 and
m2 as input and computes their sum, storing the result in another 2D integer array
result.
We have also defined a function printMatrix that takes a 2D integer array matrix as input and prints it to the console.
In the main function, we have declared two 2D integer arrays matrix1 and matrix2 and initialized them with some values. We have also declared an empty 2D integer array result.
We then call the addMatrices function, passing matrix1, matrix2, and result as arguments.
Finally, we print the original matrices and the result matrix using the printMatrix function.
Output:
Matrix 1:
1 2 3
4 5 6
Matrix 2:
6 5 4
3 2 1
Result:
7 7 7
7 7 7
As we can see, the program successfully computes the sum of the two matrices and stores the result in result.
