Why C language learning in linux?

 

OK, let's star!

 

Step 1: open terminal and input vi hello. c to create a c source file.

 

Then we enter the VIM editor and write a helloworld code.

 

Input: wq save

 

Then we can compile the program and input gcc hello. c-o hello, which means to compile the previously written hello. c program named hello.

 

Then we run the program named hello to see if "hello world!" is displayed on the screen !"?

 

What if we encounter a compilation error? Or the previous helloworld code. Let's try to get the result of removing a semicolon.

 

As a result, the compiler successfully prompts us where an error occurred.

 

OK. Next, let's try a slightly more complex program:

 

This is the code for finding the maximum common divisor of two numbers. Next we compile and run

 

See how it works.

 

OK. Now, we can successfully start C Programming on linux.
