CIS 150 C++ Programming Project: Selection, output formatting

Objectives

1. Use selection
2. Get user input
3. Perform calculations
4. Demonstrate output formatting

Program requirements

1. Include documentation comments at the start of the file.
2. Follow the course style guidelines including indentation, naming conventions, spaces instead of tabs, etc.
3. Display a menu with four options as follows:

     Convert inches to:
     1. feet
     2. yards
     3. centimeters
     4. meters
     
     Enter choice: 

4. Get the menu choice from the keyboard.
5. If the user entered a choice not available on the menu, display an error message and end the program.
6. If the user entered a valid choice, prompt the user for and get the number of inches. This should be required to be an integer (NOT a floating point number).
7. Do the appropriate conversion and display the result with a meaningful message. Feet and yards must display integer values. Centimeters and meters must display floating-point values with one digit after the decimal point.

Conversion formulas

• To convert inches to feet the formula is: feet = inches / 12. Use modulus to get the inches left over. Display both feet and inches.
• To convert inches to yards the formula is: inches / 36. Use modulus to get the feet and inches left over. Display yards, feet and inches. Remember that the value for feet should not include those in yards.
• To convert inches to centimeters the formula is: inches / .39370. Display 1 digit to the right of the decimal point.
• To convert inches to meters the formula is: inches / 39.370. Display 1 digit to the right of the decimal point.

Points

• 2 points: Proper documentation comments
• 3 points: Follows style guidelines used in class (indentation, no tabs, variables names start with lowercase letter, etc.)
• 2 points: Menu displays properly (as shown in sample runs)
• 2 points: Program prompts user and gets menu choice from user
• 2 points: Program ends with error message for invalid menu choice
• 3 points: Inches to feet conversion done properly (to feet and leftover inches) and has meaningful result message
• 5 points: Inches to yards conversion done properly (to yards, feet and leftover inches) and has meaningful result message
• 3 points: Inches to centimeters conversion done properly and has meaningful result message
• 3 points: Inches to meters conversion done properly and has meaningful result message
• 4 points: Output formatting is integer for yards, feet, and inches, and has one digit showing after the decimal for meters and centimeters

Example runs

Note: These example runs show several runs of the sample program.

Convert inches to:
1. feet
2. yards
3. centimeters
4. meters

Enter choice: 6
Error: Invalid menu choice

Convert inches to:
1. feet
2. yards
3. centimeters
4. meters

Enter choice: 1
Enter the number of inches: 27
That is 2 feet, 3 inches

Convert inches to:
1. feet
2. yards
3. centimeters
4. meters

Enter choice: 2
Enter the number of inches: 99
That is 2 yards, 2 feet, 3 inches

Convert inches to:
1. feet
2. yards
3. centimeters
4. meters

Enter choice: 3
Enter the number of inches: 27
That is 68.6 centimeters

Convert inches to:
1. feet
2. yards
3. centimeters
4. meters

Enter choice: 4
Enter the number of inches: 27
That is 0.7 meters
