Programming with C++ Lab - Lab 1 (10 points)

Part A: Area / Volume

Program Instructions:

GOAL 1:

• A complete C++ Program has been provided for you as a text file.
• This program prompts the operator to enter length and width, calculates the area of a rectangle, and displays the result.
• Access this code file in volume.txt
• Copy and paste it into your compiler.
• Build and execute it.

GOAL 2:

• Change the program to calculate the volume of a box.
• Declare double data objects for length, width, height, and volume.  (You will no longer need a data object for area).

SUBMIT:

• Document (MS Word or something similar) that contains:
  • Source Code: volume.cpp (Goal 2 only)
  • Logic Plan:  Flowchart or pseudocode.
  • Output: Screenshot of program execution.

Lab 01 -- Part B: Miles per Hour

 

DESCRIPTION:

• This program uses console I/O to calculate average speed.
• INPUT
• Number of miles driven -- data type?
• Hours elapsed -- data type?
• OUTPUT
• Average speed (MPH) displayed in a complete sentence.
• PROCESSING
• Formula for calculating MPH:   mph = miles / hours

PROGRAM INTERACTION:

Enter miles driven:
282.6

Enter driving time (hours):
4.5

The vehicle drove 282.6 miles in 4.5 hours.
Average speed is 62.8 miles per hour.

TEST DATA SETS:
 

Miles Driven	Driving Time	MPH
282.6	4.5	62.8
1741.0	32.0
31.8	.6

LOGIC:

• Prior to coding, develop your logic plan to do the following:
1. Prompt for miles and hours.
2. Calculate average speed using the formula provided.
3. Display output as shown in Program Interaction (above).

 

CODING:

• Start a NEW C++ program - speed.cpp. See Suggested Program Structure below.
• Select identifiers and data types for the data objects.

SUBMIT:

• Document (MS Word or something similar) that contains:
  • Source Code: speed.cpp (Goal 2 only)
  • Logic Plan:  Flowchart or pseudocode.
  • Output: Screenshot of program execution.
