Counting the number of times a value appears in an array

Question

So what\'s a good, simple algorithm to create a loop in C# where every time a certain value appears in an array it adds 1 to a counter in another array?

For example

Answer 1

your count array has 4 fields ...

one with the index 0, 1, 2 and 3

so what will happen if a number like 4 (or greater) happens to be counted? yor code tries to access index 4 ... which does not exist ...
