Lesson 4 - If (Strings)

If Statements can work with strings too!

Read the following program then try it:

Notice that putting the comparison you want in quotes is how you can compare string values to a string variable (answer). It will check for exactly what is in the quotes and compare it to your variable.

You can also compare multiple things with BOOLEAN OPERATORS (and, or, not). These will be in blue if you type them correctly. They are case sensitive!

Lesson 4 Assignment:

Make a calculator program that does the following:

• it asks you for 2 numbers
• it asks you if you want to ADD, SUBTRACT, or MULTIPLY the two numbers
• it gives you the result of the math function you chose then ends
• if the user does not enter a word matching the 3 options, it says you did not pick a valid option and ends
• put your name on line 1 in comments
• make the output look EXACTLY like the output below
