Lets Start C programming

                  Lets start our first program. Before it you need a compiler to compile our program. Commonly used C compiler is Turbo C (* It's not working in windows vista or windows 7. But can work using some techniques). Click here to download C compiler will not working  in windows 7 or in vista.

First of all we need to know some keywords to communicate with computer.

****The downloaded file must save in c drive of your computer.****
Then open TC/BIN/TC.EXE.

Some basic C commands are :-

 Printf  :- To print something

               eg. printf("Something to display")

Scanf  :- To accept some inputs.

               eg. scanf("%d",a);

               * Here %d is used for show a is an intiger.

Some Data type 

Data Type	Range	Data Type	Range
char or signed char	-128 to 127	unsigned char	0 to 255
int or signed int	-32768 to 32767	unsigned int	0 to 65535
long int or signed int	-2147483648 to 2147483647	unsigned long int	0 to 4294967295

C program

#include <stdio.h>

main ()

{

statements

}

  A basic c program is just like like above. Here the #include<stdio.h> is header file. Here stdio.h is standard input output functions. Many functions are there to work different functions like math.h , conio.h etc..

Then the main() part is to indicate the main function starts here.

We give statements with in { }.
