The second generation language programmers.

No. It would be a third generation programming language.

Yes.

Third generation. All high level languages are third generation. Assembly language and low-level symbolic languages are second generation languages. Machine code is the only first generation language. Although some languages have been described as being fourth or fifth generation, the terms have no official meaning (they were originally used by marketing types but are in fact meaningless).

There is no such thing as a fourth generation language.

Machine code is the first generation (the native language of the computer). Assembly language is the second generation (low-level symbolic language). All high-level (abstract) languages are third-generation.

Although some languages claim to be fourth-generation or even fifth-generation, they are meaningless terms used by marketing types that tell you nothing about a language's capability.
