9/28 Write a program to swap the values of two variables

Question

Write a program to swap the values of two variables. The program will ask the user to input variables x and y with numerical values. You must write code that exchanges their values: the value of x after your code runs must equal the value that y had before your code ran, and the value of y after your code runs must equal the value that x had before your code ran.
