What is C Programming Language ?
C is an all-purpose, structured programming language. A programming language is a language you can use to write a computer program that is executable on the computer. C Programming falls under the category of middle level languages—ones that are powerful enough to perform low-level tasks but still easy enough for beginners to learn (which makes it perfect for teaching!). This flexibility allows C to do anything from operating system development all the way up through application development. It also resembles other high level structure programming languages like Pascal and Fortran.
Why to learn C language ?
The language 'C' is the base language of many other programming languages, so learning it will be useful throughout your studies. A number of concepts are shared among these languages, such as data types, operators, control statements, and so forth. C is the world's most widely-used programming language, which means that it has a lot of functionality and also runs at faster speeds. There are a lot of jobs available for a developer who possesses a C-level expertise in today's market.
in 'C' (a structured programming language) programs are composed of modular components that can be written separately and combined to create one program. The architecture makes testing, maintaining, and debugging simpler.
c provides 32 keywords, a variety of data types, and some powerful built-in functions, making programming very efficient.
'C' programming is capable of growing through new functions. A 'C' program is made of various library functions. We can extend our library with our own features and functions. These functions can be accessed and used whenever we want in our program, which simplifies complicated coding.
You can use many different programs, commonly called compilers, in order to execute a program written in this language. C language programs are very portable and can be used on other machines.This feature is essential if we wish to use or execute the code on another computer.
C is a compiled programming language. Compiling a program (using a compiler) translates it into an object file—a kind of code that's readable by the machine but not human beings.Once the compilation process is complete, the linker connects together all the different files to create a single executable file capable of running the software. The following diagram illustrates how this C program runs.
These days, there are plenty of free compilers for C out there for programmers to choose from and although each one may offer slightly different features (depending on what type of software they're designed for), most can work with both C and C++—meaning you don't need multiple copies if you want to develop or experiment with both types of languages.
