Language C

In the present modern age era where so many other languages are available to learn, than why Language C. But why ‘C’ and not Java or Basic or Perl? Mostly because of memory allocation. Unlike most computer languages, C allows the programmer to address memory the way he/she would use assembly language. Languages like Java and Perl shield the programmer from having to worry about memory allocation and pointers. This is usually a good thing. It’s quite tedious to deal with memory allocation when building a high-level program like a quarterly income statement report. C is a remarkable language, it has increased in use until now it may well be one of the most widely written¬†computer languages in the world. The success of C is due to a number of factors, none of them key, but all of them important.

The success of C is really remarkable. The most popular Operating Systems right now are Microsoft Windows, Mac OS, Linux, each is written in C language. The most popular web applications Apache, MySQL, PHP are also written in C Language. Another thing if you want to learn any language it is very important to learn C.

The language C is inter-connected with all other languages of the computer. Whether you learn any language the concepts of C will be available in all languages. Either it is declaration of variables, loops or operators etc., thing some how relate to C Language. If you have learned the C, then basic of any language may be easily understandable.

Can you Learn C yourself?

In the early stages of learning to program you need a protective environment that gives feedback on mistakes and helps you to get results quickly – programs that run, even if they don’t do what you meant. C is not like that! A professional forester would use a chain-saw to cut down trees quickly, aware of the dangers of touching the blade when the machine is running; C programmers work in a similar way. Although modern C compilers do provide a limited amount of feedback when they notice something that is out of the ordinary, you almost always have the option of forcing the compiler to do what you said you wanted and to stop it from complaining. Provided that what you said you wanted was what you really did want, then you’ll get the result you expected. Programming in C is like eating red meat and drinking strong rum except your arteries and liver are more likely to survive it.

Developer Expectations

Developers have expectations about what language constructs mean and how implementations will process them. At the very least developers expect a translator to accept their existing source code and generate to a program image from it, the execution time behavior being effectively the same as the last implementation they used. Implementation vendors want to meet developer expectations whenever possible; it reduces the support overhead and makes for happier customers. Authors of translators spend a lot of time discussing what their customers expect of their product; however, detailed surveys of customer requirements are rarely carried out.

Three commonly encountered expectations are good performance, low code expansion ratio, and no surprising behavior; the following describes these expectations in more detail.

C has a reputation for efficiency. It is possible to right programs that come close to making optimum usage of processor resources. Writing such code manually relies on knowledge of the processor and how the translator used maps constructs to machine code. Very few developers know enough about these subjects to be able to consistently write very efficient programs. Your author sometimes has trouble predicting the machine code that would be generated when using the compilers he had written. As a general rule, your author finds it safe to say that any ideas developers have about the most efficient construct to use, at the statement level, are wrong. A cost-effective solution is to not worry about statement level efficiency issues and let the translator look after things.

C has a reputation for compactness. The ratio of machine code instructions per C statement is often a small number compared to other languages. It could be said that C is a WYSIWYG language, the mapping from C statement to machine code being simple and obvious (leaving aside what an optimizer might subsequently do). This expectation was used by some members of WG14 as an argument against allowing the equality operator to have operands with structure type; a single operator potentially causing a large amount of code, a comparison for each member, to be generated. The introduction of the inline function-specifier has undermined this expectation to some degree (depending on whether inline is thought of as a replacement for function-like macros, or the inlining of functions that would not have been implemented as macros).

C has a reputation for being a consistent language. Developers can usually predict the behavior of the code they write. There are few dark corners whose accidental usage can cause constructs to behave in unexpected ways. While the C committee can never guarantee that there would never be any surprising behaviors, it did invest effort in trying to ensure that the least-surprising behaviors occurred.
