 hi,friendz,how are you? now i'm showing how solve The addition, subtruction, division and multiply of Matrix via programming C.To solve this problem , you need to know about for loop and array.At first try to solve it .then if you don't solve it see this. If you want to be a good programmer "there is no alternate way of practices"
The solution:
