Transcribed Image Text:Swapping Values
Summary
In this lab, you complete a C++ program that swaps values stored in three int
variables and determines maximum and minimum values. The C++ file
provided for this lab contains the necessary variable declarations, as well as
the input and output statements. You want to end up with the smallest value
stored in the variable named first and the largest value stored in the variable
named third. You need to write the statements that compare the values and
swap them if appropriate. Comments included in the code tell you where to
write your statements.
Instructions
1. Ensure the Swap.cpp file is open in your editor.
2. Write the statements that test the first two integers, and swap them if
necessary.
3. Write the statements that test the second and third integer, and swap
them if necessary.
4. Write the statements that test the first and second integers again, and
swap them if necessary.
5. Execute the program by clicking the Run button at the bottom of the
screen using the following sets of input values.
