Lab 2 - Variables, cin and Math

Starting with this lab set, points will be deducted for incomplete comments, and for not following the filename conventions in the assignment. You should make sure that the comments that list your name, assignment, etc. at the top are correct, and that you add comments throughout your code.

Each lab in this group will be worth 10 points (except the calculator). 7 points will be for creating a project that works, and 3 points will be for style (comments, following proper indenting rules, etc.)

Lab2_1 (int and float)

• Project name: yourname2_1
• cpp file name: yourname2_1
• Create a program that has one integer variable and one float variable. You can use any name for these variables that you want. Use names that make sense, such as 'x' or 'y', or num1 and num2. Do NOT use silly variable names such as "booger1" or "couchpotato2."
• Initialize the integer variable to 7, and the float variable to 7.987.
• Output each value on its own line.

Lab2_2 (char and bool)

• Project name: yourname2_2
• cpp file name: yourname2_2
• Create a program that has one char variable and two bool variables. You can use any name for these variables that you want.
• Initialize the char variable to 'Y' and one of the bool variables to true, and the other to false
• Output each value on its own line

Lab2_3 (user input - cin)

• Project name: yourname2_3
• cpp file name: yourname2_3
• You must write pseudocode for this project before you begin. Clear your pseudocode with Mrs. Sanchez before beginning your project (pseudocode == 3 points, program = 7 points)
• What is pseudocode?
• Create a program that lets the user input 3 int values and 3 float values.
• Each time the user inputs the value, display it back to the screen.

Lab 2_4 (math + and -) pseudocode: 3 points program: 7 points

• Project name: yourname2_4
• cpp file name: yourname2_4
• You must write pseudocode for this program. Clear your pseudocode with Mrs. Sanchez before you begin.

Create a program that:

• asks the user to input two int values
• Add the two numbers together and output the result
• subtract the second value from the first and output the result
• subtract the first value from the second and output the result

Lab 2_5 (math * and /) pseudocode: 3 points program: 7 points

• Project name: yourname2_5
• cpp file name: yourname2_5
• You must write pseudocode for this program. Clear your pseudocode with Mrs. Sanchez before you begin.ask

Create a program that:

• asks the user to input two float values
• multiply the values and output the result
• divide the first value(denominator) into the second value (the quotient) and output the result

Lab2_Calculator (ongoing project) (20 points)

• Because we will use this calculator program in many labs this semester, it does not have the usual project file name of labx_y. You should name this project "myname_calculator".
• Before you can begin programming your calculator, you *must* write the pseudocode and have it approved by Mrs. Sanchez. If you start early, you will lose points.
• You will not actually start this program until we learn to do "if" loops (next week)
• Right now, your calculator should allow the user to input three integers.
• You will then ask the user what math operation they wish to perform (add, subtract, multiply, or divide)
• After your program does the appropriate calculation, output the answer to the user
