Lesson objectives

10.4.1.1 Write code in a programming language using functions and procedures

Success criteria
Describes the function / procedure parameters
Uses function / procedure when solving problems
Creates its own function / procedure to solve practical problems

4

Write a procedure called “Display” that will prompt the user to enter two integer numbers n and m, and will display all the numbers from n until m. i.e.
If n = 4, m = 9 it will display: 4 5 6 7 8 9
Also, write the main program to call the procedure “Display”.
Draw the flowchart of the above program.

Descriptors:
Student
correctly writes a procedure and the main program;
correctly draws the flowchart of program.

5

Write a procedure called “Sum” that will prompt the user to enter two integer numbers n and m, and will display the sum of all the numbers from n until m. i.e.

If n = 2, m = 6 it will display: 20
since 2 + 3 + 4 + 5 + 6 = 20
