Programming (Part-2)

Before learning C programming, we need to know how the computer works. The computer works exactly the way the brain works. Just as we can see with regard to the eyes or listen with ears, we can think only about our brain. Then, when the brain reaches a discipline, we effect the brain decision with our hands or legs.

                                                                   

Now let's look at the matter with a computer. Listening with eyes or hearing something with ears means that input is provided. And the decision of the brain is to process. And to solve the work with our own hands is our output. So, any Programming Language from C, even the whole world's work, follows this formula.

                                                   Input -> Processing-> output

What is the need of programming language?

I do not know how the computer works. But why programming language?

Programming language is a language that allows computers to work. Although the fact is that the computer only understands nothing except 0 and 1. Should the computer use all the directions 0 and 1? But then writing the program will become very complex.

It is a matter of confidence that in the beginning, using the program only using 0 and 1, but after the release of this problem, every instruction started using the metaphor (eg ADD, SUB, etc). This is called Assembly Language. Along with this, Assembler is a software that converts metaphor instruction into auto machine language.

But there are problems with this assembly language. To write a program here, people who know a lot about the machine can program. So how do I or you?

For our convenience, developers gradually discover a little high level language such as C, C ++, Java etc. so that our machine does not know much about the details.

Structure of C program

C is a mid-level programming language. The main part of the main part is basically three.

1. Header file

2. main () function

3. Others Function.

The C program is composed of one or more functions. Each C program has a user defined function named main (). A small C program can be written as

main ()

{

            // C is a case sensitive programming language

}

Say good if you write main () in the place of main (), then your compiler (which C will write in the program) will reboot. Again you will have to do semicolon in some places. If you do not give a semicolon space or if you do not give a semicolon, you will get the error.

As you would like to give instructions inside the main () function, the semicolon must be at the end. Suppose you are trying to print a line. In that case, you have to use the printf () function.

As mentioned earlier, a header file is required to declare C program. The process of declaring header files,

#include <header file>

 

Many things we know. Now, running a program should start the programming part. You can start C programming with any compiler. Turbo C, codeblocks anything. If you do not have codebalk software on your computer you can easily take it off the net.

        http://www.codeblocks.org/downloads

You can go to this address and go to download binariae release and install it.

If code-blocks are installed, open a new project and you see a window like this.

From there click on the Console application and save the location by typing the name of the program and the new window to write the program.

Or you can also open a new project from the file.

  

                     The computer only understands nothing except 0 and 1

 

Now we will write a program. The first C program to write to us!

#include <studio.h>

main ()

{

printf ("I am a C programmer");

)

 

By typing in the top and clicking on the top green button you can see the program on a separate screen-

I am a C programmer.

This way you can easily write your first program.

Now hold that you want to write two lines. What will you do? Very simple. The printf will be written twice.

#include <studio.h>

main ()

{

printf ("I am a C programmer");

printf ("I am a C programmer");

)

 

I am a C programmer, I'm a C programmer, there are two line outputs.

But you are looking

I am a C programmer

I'm a C programmer.

In that case you need to add \ naddress to the end of the first line. \ n means new line.

#include <studio.h>

main ()

{

printf ("I am a C programm \ n");

printf ("I am a C programmer");

)

Well, before you connect the second line \ n will you get your desired output? Do not practice yourself ... 😀

In the beginning, the lines will be typed repeatedly without copy paste. And in the next phase, we have come up with some more common topics in C programming. Again, I am going to say that I will try to give some basic concepts of basic programming in Basic C ++, basics, through a few episodes. Through this you can not learn programming. I know. But it also knows that after reading all the episodes, there might be some interest in learning your programming. And if you are interested, you will not learn how fast you will learn programming. 😀

Happy Programming .. 😀
