Swap Two Numbers by Reference

Write a function void swapValues(int &a, int &b) that swaps the two integers using reference parameters. In main, a = 5 and b = 9; call swapValues(a, b) and then print them so the output is exactly what is shown in Expected Output.

Reference parameters (int &a) let the function change the caller's variables.

Expected Output:

a=9 b=5↵

= newline. The output ends with a newline — print one after the last line.
