Understanding and Preparing Flowcharts

Flowchart:

• A flowchart is a diagram that shows the steps of a process using symbols and arrows.
• It helps to plan a program before writing code.

Common Symbols in Flowcharts:

• Oval (Ellipse): Start / End
• Parallelogram: Input / Output (data in, result out)
• Rectangle: Process (calculation or action)
• Diamond: Decision (Yes/No, True/False)
• Arrow: Flow of direction

Example: Flowchart to add two numbers

1. Start (Oval)
2. Input two numbers (Parallelogram)
3. Add numbers (Rectangle)
4. Display result (Parallelogram)
5. End (Oval)

Evolution of Programming Language

Programming languages have developed in different generations:

1. Machine Language (1st Generation)
   • Written in 0s and 1s (binary).
   • Very difficult to understand.
   • Example: 10110011.
2. Assembly Language (2nd Generation)
   • Uses short words called mnemonics (ADD, SUB, MOV).
   • Easier than machine language.
   • Needs assembler to convert into machine code.
3. High-Level Languages (3rd Generation)
   • Written in English-like statements.
   • Easy to learn and understand.
   • Needs compiler/interpreter to convert into machine code.
   • Examples: C, BASIC, FORTRAN, Pascal.
4. Very High-Level Languages (4th Generation)
   • Focuses on what to do rather than how to do it.
   • Used in database and application development.
   • Examples: SQL, MATLAB.
5. 5th Generation Languages
   • Based on Artificial Intelligence (AI) and logic.
   • Examples: Prolog, Mercury.

Types of Programming Language

1. Machine Language
   • Binary (0s and 1s).
   • Very fast but hard to write.
2. Assembly Language
   • Uses mnemonics.
   • Easier than binary.
3. High-Level Language
   • English-like words.
   • Portable and widely used.
   • Examples: C, C++, Java, Python.
4. Object-Oriented Language
   • Based on objects and classes.
   • Encourages reusability and modular coding.
   • Examples: Java, C++, Python.

Key Points to Remember – Problem Solving Programming

• Flowchart = diagram with symbols showing step-by-step solution.
• Programming languages evolved from binary → mnemonics → English-like → AI-based.
• Types: Machine, Assembly, High-level, Object-oriented.
