Question

Why we use Multidimensional Arrays?? I can't understand it... It looks like make more complexes

Answer 1

Basically multi dimension arrays are used if you want to put arrays inside an array.

Say you got 10 students and each writes 3 tests. You can create an array like: arr_name[10][3]

So, calling arr_name[0][0] gives you the result of student 1 on lesson 1. Calling arr_name[5][2] gives you the result of student 6 on test 3.

You can do this with a 30 position array, but the multi dimension is:

1) easier to understand

2) easier to debug.
