Hello World

This is the basic step of every programming languages. Hello world may the first step.
In C language we use stdio.h (header file) for standard input and output. The header file stdio includes "printf" function. printf is used to print output.

#include <stdio.h> main() { printf("Ajmal Joshi Greets You"); getch(); }

Now check the above first code.

#include : is used to import the header files. Here I want to print a function so I need to import the header file for print function. stdio.h is the header file which includes print function.

main() :Tells the computer program starts.

{ (Opening brace) : Opening brace is the starting place of Declaration and Execution part.

} (Closing brace) : It is the ending place of Declaration and Execution part.

printf : printf is used to print message.

getch() : getch() is used to open compiled file in a stable console

     How to make printf some more advanced.

#include <stdio.h> main() { printf("Ajmal Joshi Greets You"); printf("Good Morning"); getch(); }
Here I used two printf functions. My target is to print "Ajmal Joshi Greets You" in one line and "Good Morning" in another line. But result of this code is "Ajmal Joshi Greets YouGood Morning".
We can use the "\n" for solve this problem.

#include <stdio.h>main() { printf("Ajmal Joshi Greets You"); printf("\n"); printf("Good Morning"); getch(); }

Yeah solved that. But we can use this in one printf function.

#include <stdio.h> main() { printf("Ajmal Joshi Greets You\nGood Morning"); getch(); }

Solved this problem in One line.
