Learning Objectives: After completing this lab the student will be able to:

$$ Use the relational and logical operators to write conditional expressions.

$$ Write if statements to select a block to be executed when a conditional expression is true.

$$ Write if$-$else statements to select one block or a different block to execute based on the result of a conditional

expression.

Part $1$ Relational Operators and the If Statement

In your C$++$ IDE, create a new project named Lab $5$ Part $1,$ or something similar. Add a C$++$ source code file named lab$5-$

$1.$cpp to the project. Then copy$-$and$-$paste the code below into lab$5-1.$cpp$.$

$//******************************************************************************$

$//$ PROJECT: Lab $5$ Part $1$

$//$ FILE: lab$5-1.$cpp

$//$

$//$ DESCR: This project will help you learn the difference between the C$++$

$//$ assignment operator $=$ and the C$++$ relational equality operator $==.$

$//$ They are completely different operators and they work in completely

$//$ different ways.

$//$
