C Programming – Features & The First C Program
Most important features of C programming were Portability and less lines of code.
Have you ever wondered why a company like Google for example has separate
departments for carrying out different tasks for the same job ? If the job is to
develop a software, then there might be a separate department for requirement
analysis, a separate. department for. requirement analysis or design phase. This is
the distinction between High level. language and low level language. Abstraction
means hiding system level details. Therefore, high degree of abstraction means less
efforts to the user. C language is called middle level language because it makes
programming simpler for human beings. On the other hand it also allows us to access
system level features such as Direct access to memory through pointers and Bit
manipulation using bitwise operators. This makes programming a cake walk for
programmers and that is obviously a great advantage. I would recommend you to
download Code Blocks IDE to execute code on your own. Code Blocks is an integrated
development environment that helps you in creating C programs efficiently. C
function consists of group of statements intended to solve a particular problem. On
the other hand variables are the entities used to store values which are used
during computation. Compiler actually look forward to this particular function and
it is the starting point of your program. # include simply requests processors to
include the file stdio. h.
The last statement that I have written here is , return 0 It indicates that if your
statements complete execution successfully , then return integer 0 and exit from
the function. After the name of the function, you can see some lists of parameters
which are enclosed within the round brackets. These are called the inputs to your
function. In our example, main function does n't have any parameters. It is mostly
defined like that way. But if you want , you can add parameters arcc and arcv whose
values is been provided at run time using command line arguments. Build and Run are
required for the execution of your code. Build asks the. compiler to build the
machine code for the source code we had written. And Run simply runs the code and
produces the output. If you are not making any changes to the code, then you have
to build it again and Run. Neso Academy is printed. Make these changes to the code
and see what happens. Please make the changes one by one and not all at the same
time. Comment out the # include. Remove the semicolon after printf. Remove int
return type from main. Instead of 0 in return write any integer value you want.
Replace 0 with some character. Characters are usually written with single quotes.
