Homework #3
For all program assignments in SURE 272, provide the following information with any
program:
• Print your program code and the form image and attach to your report
• Explain how your program works using a pseudo code or a flow chart
• Create a new folder for each program \HMK3\PROG1\
• Save your program project, executable and form on a floppy disk (different
folder for each program and attach the floppy disk to the report binder.
• Declare all your variables in the general declaration section
• Write comments in the body of your program to explain ever step
• Attach the code to the assignment report.
1. Write a program that given a slope distance, and vertical angle, height of the

3. Answer question 5 (page 128) in the programming projects of the course textbook.
Note the algorithm converts the English units into inches and then use the INT
command (INT returns the first integer less than or equal to number)
Total inches = 63360 × miles + 36 × yards + 12 × feet + inches
Total meters = total inches/39.37
Kilometer = INT(meter/1000)
Meters = INT(Total_meters - (km * 1000))
Centimeter = ?
Add another button that converts from metric units to miles, feet and inches.
Total 1 mile = 5280 feet, 1 yard = 3 feet, 1 foot = 12 inch,
1 inch = 2.54 cm, 1 ft = 0.3048 m, 1 mile = 1.60934 km
