Three programming languages

Answer 1

1GL or first-generation language was (and still is) machine language or the level of instructions and data that the processor is actually given to work on (which in conventional computers is a string of 0s and 1s). 2GL or second-generation language is assembler (sometimes called "assembly") language. A typical 2GL instruction looks like this: ADD 12,8 An assembler converts the assembler language statements into machine language. 3GL or third-generation language is a "high-level" programming language, such as PL/I, C, or Java. Java language statements look like this: public boolean handleEvent (Event evt) { switch (evt.id) { case Event.ACTION_EVENT: { if ("Try me" .equald(evt.arg)) { A compiler converts the statements of a specific high-level programming language into machine language. (In the case of Java, the output is called bytecode, which is converted into appropriate machine language by a Java virtual machine that runs as part of an operating system platform.) A 3GL language requires a considerable amount of programming knowledge. 4GLor fourth-generation language is designed to be closer to natural language than a 3GL language. Languages for accessing databases are often described as 4GLs. A 4GL language statement might look like this: EXTRACT ALL CUSTOMERS WHERE "PREVIOUS PURCHASES" TOTAL MORE THAN $1000 5GL or fifth-generation language is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. Visual programming allows you to easily envision object-oriented programming class hierarchies and drag icons to assemble program components.

Answer 2

If you have to ask, you don't.

It takes a tremendous lot of thought, knowledge, experience , time and effort to create

a programming language and then there is the question - why? Will your language really be

any better than the existing languages? Even if it is, will anybody want to learn it--

will anybody want to buy it?

Answer 3

There is no such thing as a 5GL language. The term 5GL is used by marketing types to make their products seem superior to rival products but it has no actual meaning since no such definition ever existed. Languages are defined by their paradigms and/or by the types of problems they were intended to resolve.

Answer 4

That depends on who you speak to. Some people regard the first generation as being raw machine code, the second generation being the low-level assembler languages while the third generation covers all high level languages.

However, historically, there was no such thing as first or second generation languages until the introduction of the third generation hardware. At this point the high level languages shifted their focus, favouring the programmer rather than the computer, easing the burden on the programmer. These languages became known as the third generation languages to coincide with the hardware shift, while older high level languages became the second generation and assembly language reflexively became the first generation.

Answer 5

Machine Language is an example of first generation programming language.

Fortran is an example of second generation. It allowed the language to be written more towards how a programmer thought and then compiled. Also called a High Level programming language.

C, Pascal and Basic are examples of third generation languages where getting away from hardware dependence was important.

RPGII and Clipper are an example of fourth generation languages that were designed with set of design patterns for development of commercial business software.

Prolog is an example of a fifth generation language based on solving problems using constraints given to the program.

Answer 6

First generation programming languages are referred to as machine language. The primary advantage of machine language is that unlike in higher level languages, it does not have to be compiled or assembled.
