C Language

C program consists of functions and declarations or instructions given to the computer to perform a particular task. The process of writing a program involves designing the algorithm, a flowchart may also be drawn, and then writing the source code, after developing the program you need to test it and debug it if it does not meet the requirement. To make a program you need a text editor and a compiler. You can use any text editor of your choice and a compiler. C compiler converts source code into machine code that consists of zero and one only and directly executed on machine. An IDE or Integrated Development Environment provides a text editor, compiler, debugger etc. for developing programs or projects. Download Codeblocks IDE it provides an ideal environment for development. It can import Microsoft Visual C++ projects, extendable as it uses plug-ins, open source and cross platform.

C Program

A c program must have at least one function which is main, function consists of declaration and statements, a statement is an expression followed by a semicolon, for example a + b, printf("c program examples") are expressions and a + b; and printf("C is an easy to learn computer programming language."); are statements. To use a variable we must indicate its type whether it is an integer, float, character. C language has many built in data types and we can make our own using structures and unions. Every data type has its own size that may depend on machine for example an integer may be of 2 or 4 Bytes. Data is stored in binary form i.e. group of bits where each bit may be '0' or '1'. Keywords such as switch, case, default, register etc. are special words with predefined meaning and can't be used for other purposes. Memory can be allocated during compile time or at run time using malloc or calloc. C language has many features such as recursion, preprocessor, conditional compilation, portability, pointers, multi threading by using external libraries, dynamic memory allocation due to which it is used for making portable software programs and applications. Networking API's are available using which computer users can communicate and interact with each other, share files etc. C standard library offers functions for mathematical operations, character strings and input/output and time. The process of making programs which is known as coding requires knowledge of programming language and logic to achieve the desired output. So you should learn c programming basics and start making programs. Learning data structures such as stacks, queues, linked lists etc. using c programming provides you a greater understanding as you learn everything in detail. General belief is to go for other high level languages but it's a good idea to learn c before learning C++ or Java. C++ programming language is object oriented and it contains all the features of c language so learning c first will help you to easily learn C++ and then you can go for Java programming.
