Multi dimensional arrays in c++

Question

How to perform operations like multiplication addition subtraction division on 2-D and 3-D array

Answer 1

Lets suppose you have:
Int x[2]{2,3};
Int y[2]{2,3};
Int z[2]{1,4};
Now you want to sum 2 + 3, and multiply it for 4 and print the answer:
Int number = (x[0] + y[1]) * z[1];
cout<<number<<endl;
