C Language | Hello World a start with programming

C language is a basic programming language used to create simple to complex programs. C has different kinds of commands such as pre-processors, arrays, strings, if else statements and switch case statements. During my first lecture in this subject, programming, my professor introduce to us C language using the well known Hello World program. So, to introduce to you C language I will show you the Hello World program.

In this program, we used simple codes. We have there the pre-processor command which is the #include and the header files stdio.h and conio.h. There is also our command for output which is the printf. Lastly, to terminate the program getch(); is the key for that. It prompts user to input any character that will not show but rather to terminate the program. Check out the codes below.

   1:  #include <stdio.h>

   2:  #include <conio.h>

   3:   

   4:  int main()

   5:  {

   6:  printf("Hello World!");

   7:  getch();

   8:  }
