Without them you wouldn't be able to program :P. Besides that though, each programming language has a different level of abstraction, meaning how closely they resemble machine code. Low-level programming languages closely resemble machine code while high-level languages more closely resemble actual words and are more intelligible. Low-level languages are generally considered harder to learn than high-level languages and take more instructions to do something than a program made in a high-level language made to do the same task.
why do we have diffrent programming laungage
Programming languages (or natural languages) cannot be downloaded.
Programming languages (or natural languages) cannot be downloaded.
You cannot install programming languages (or natural languages, either) on your computer. You can install compilers for programming languages, though.
high level programming languages are languages that are given by the programmer to the system as a input and they are understandable by a programmer
No.
Common questions about syntax in programming languages include: "What is syntax and why is it important?", "How does syntax differ between programming languages?", "What are some common syntax errors and how can they be avoided?", and "How can I improve my understanding of syntax in a programming language?"
There are no 'partial' programming languages.
actually oop concept have some disadvantage when compared to structured programming
Programming languages such as COBOL and FORTRAN are examples of procedure languages.
No, but of course there is a programmers' slang. And programming is done with so-called 'programming languages'.
Yes, that is the standard in many programming languages.Yes, that is the standard in many programming languages.Yes, that is the standard in many programming languages.Yes, that is the standard in many programming languages.
