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 separa
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 huma
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
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 developme
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 execu
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 you
function. In our example, main function does n't have any parameters. It is mostly defined like that way. B
you want , you can add parameters arcc and arcv whose values is been provided at run time using comma
line arguments. Build and Run are required for the execution of your code. Build asks the. compiler to buil
machine code for the source code we had written. And Run simply runs the code and produces the outpu
you are not making any changes to the code, then you have to build it again and Run. Neso Academy is pr
Make these changes to the code and see what happens. Please make the changes one by one and not all a
same time. Comment out the # include. Remove the semicolon after printf. Remove int return type from m
Instead of 0 in return write any integer value you want. Replace 0 with some character. Characters are usu
written with single quotes.
