The document outlines an instructional approach to programming, highlighting the differences between low-level and high-level programming languages, such as Assembly and Python. It discusses practical applications, algorithm representation through flow charts, and the use of pseudocode for problem-solving. Additionally, it describes how to build a program for determining exam grades based on provided marks.

Real-life applications of programming

3. Low Level programing language
Assembly language – a low-level chip/machine
specific programming language that uses mnemonics
total = first + second + third

4. Low Level language - Example
total = first + second + third

5. High Level programing language
High-level language programs are machine
independent, portable and can be run on any type of
computer/chip, provided there is a compiler or
interpreter available. For example, Java, Python and
Visual Basic® (VB) are high-level languages often used
for teaching programming.

6. High Level programing language
Python code:
total = 0
first =10
second =20
third =40
Total = first + second + third
Print (“Total = ”, total )

7. Problem Description
Build a program to get the exam grade for provided marks.
Mark < 40 then the Grade is Fail
Mark < 60 then the Grade is Pass
Mark < 80 then the Grade is Merit
Mark > 80 then the Grade is Distinction

8. Flow Charts
shows diagrammatically, using a set of symbols linked
together with flow lines, the steps required for a task
and the order in which they are to be performed. These
steps, together with the order, are called an algorithm

9. Flow Charts

10. Pseudo Code
Pseudocode is a method of showing the detailed
logical steps in an algorithm, using keywords,
identifiers with meaningful names and mathematical
operators to represent a solution
