I'm having some problems with C++ arrays

Question

I just don't know how arrays will be useful for me and I'm not understanding anything
As english isn't my native
Any solution??

Answer 1

If you cant understand english: Use translator.

If you dont understand the sense of arrays: Try to declare and initialise 100 integer variables and print them.
Now use an array with size 100 for the same purpose and use for loop. what was faster?
