2. Generations of
programming languages
• Based on the characteristic of various computers
developed from time to time, they're classified because
generation associated with computers.

3. First generation languages
• The first generation languages, or even 1GL tend
to be low-level languages which are machine
language.
• 1GL or even first-generation language had been
machine language or even the level of instructions
as well as data that the processor is actually given
to work on (which in conventional computers is a
string of 0s as well as 1s).

4. Second generation languages
• The second generation languages, or even 2GL will
also be low-level languages which contain
assembly languages.
• 2GL or even second-generation language is
assembler (sometimes known as "assembly")
language. A typical 2GL instruction looks like this:
• An assembler converts the assembler language
statements into machine language.

5. Third generation languages
• The third generation languages, or even 3GL
are high-level languages known as C.
public boolean handleEvent (Event evt) {
switch (evt.id) { case Event.ACTION_EVENT: {
if ("Try me" .equald(evt.arg)) {

6. Fourth generation languages
• The fourth generation languages, or even 4GL
tend to be languages that consist of statements
similar to statements in a human language.
Fourth generation languages are generally
utilized in database programming and scripts.

7. Fifth generation languages
• The fifth generation languages, or 5GL even
tend to be programming languages which
contain visual tools to assist develop a
program. A example of a fifth generation
language is Visual Basic.

8. Program Development Cycle
1) Analyze: Determine the issue
2) Design: Plan the answer towards the issue
3) Choose the Interface: Find the objects
4) Code: Translate the algorithm into a programming
language.
5) Debug and Test: Locate and also remove any
errors in the program.
6) Complete the Documentation: Organize all the
materials that identify the program.

9. Programming Tools
• Flowchart
• Pseudocode
• Hierarchy Chart (Structure chart)

10. What is a flowchart?
• Logic diagram to explain every action that the
program must perform to arrive at the solution.
• A popular logic tool used for showing an
algorithm in graphics form.
• Programmer prepares flowchart before coding.
• Most typical flowchart symbols tend to be:

11. What is a Pseudocode?
• A program design technique that uses
English words.
• Has no formal syntactical rules.

12. What is a Hierarchy Chart?
• Shows the entire program’s structure.
• Describes what each part, or even module, of
the program does.
• Also how each module relates to other
modules within the program.
