1. A. Consider the following program written in C syntax. Transform it to C# and test it using arguments with passed by value, passed by reference (use ref keyword) and passed by value-result (use out keyword).

void swap(int a, int b){ int temp; temp = a; a = b; b = temp; }

Guideline: Use the ref keyword for pass by reference, and the out keyword for the pass by value-result.

B. Using generics in C#, re-write the swap function above. Test the function by using two different data types.
