A. Declaring, Initializing, and Printing Variables

The following program contains missing code. Specifically, you are to fill in the missing code as directed below:

• Declare variable var1 as an integer, var2 as a character, and var3 and var4as floating point numbers, but do not initialize these variables yet.

• Next, assign 25 as the value of var1.

• Then, assign var2 to be the uppercase first letter of your last name. Now, assign

  var3 to be the floating-point number 2.5.

• Finally, seeing as the var4 contains the result of an arithmetic expression, print

  out the result of var4 to the terminal. Be sure to print a newline after the result.
