Multidimensional Arrays

Question

Hey guys, when should I use Multidimensional Arrays or why people use it?

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
