In programming, a "loop" is a piece of code that is allowed to execute repeatedly until a condition is met. Under C, there are "for" and "while" loops. Other languages have "foreach" and "repeat..until" loops.
A "for" loop optionally sets a variable at a certain value, and then executes a block of code while that (and perhaps other variables) meet(s) certain conditions.
"While" loops are simpler types of loops since they only loop while a condition is met - variables are set before the "while" statement.
See the related links below for more information on looping in C.
Programming is a term that describes the usage of a programming language. Programming languages (C++ for example) are languages that create programs, these programming languages should not be confused with scripting languages. Scripting languages are languages that are meant to be interpenetrated by programs. (Written in a programming language)
It depends on the programming language, however most high-level languages will provide some variant of the standard 'for' loop in addition to some variant of the 'while' and 'do-while' loop.

why do we have diffrent programming laungage
Due to the rather large number of high-level programming languages, it's difficult to say with absolute certainty that they all include a while statement. However, as loopingconstructs are fundamentally made up of goto's and labels, I would be pretty amazed to find one that doesn't at least provide an equivalent, particularly as looping is so common.It's interesting to note that there are some languages such as Scheme that are focused on purely functional programming. So even though looping can be done, it would most likely accomplish the same task using recursive functions instead.

Thousands! Programming languages number in the thousands, from general purpose programming languages such as C++, Java, and others, to special purpose languages which are used in one application. They can be ordered by type (structured, object-oriented, functional, etc.) or by history, or syntax. See the related list of programming languages.
Programming languages, like human languages, are defined through the use of syntactic and semantic rules, to determine structure and meaning respectively. Thousands of different programming languages have been created, and new languages are created every year.

Yes, characters can be used as symbols in programming languages to represent data or instructions.
You cannot install programming languages (or natural languages, either) on your computer. You can install compilers for programming languages, though.
