C++ Programming (Basic) -Revision

from input until function

Today's topics

• Basic C++ function (input, output)

• Selection control

• Repetition control

• Simple array

• Simple function

Learning outcome 1:

• How to use input\output in a program

• How to use the selection control structures if, if...else, and switch in a program.

Key term for first part

• Input output (cin, cout)

• Selection (if … else, switch, case)

Programming Question 1

Write a program that takes a given length as input expressed in feet and inches. Convert and output the length in centimeters

Convert the length in feet and inches to all inches:

–Multiply the number of feet by 12

Use the conversion formula (1 inch = 2.54 centimeters) to find the equivalent length in centimeters

Question 2

Write a c++ program for currency converter. It can convert Ringgit Malaysia to British pounds, Canadian dollars, and Japanese yen. It should also able to let the user decide which currency they wish to convert. Option menu using the switch statement and the input validation using if..else statement.

Details:

1: Input money using "cin" in a double variable

2: 1 British Pound = 5.87 Ringgit Malaysia

3: 1 Canadian Dollar= 3.37 Ringgit Malaysia

4: 1 Japanese Yen = 0.038 Ringgit Malaysia

5: Include the input validation in the system.
