Basic of c language

The general syntax of c language is-

#include <stdio.h>
int main()
{
   
}

Firstly we should know about the data type

There are several data type

1.int

Int is used for integer variable

2.char

Char is used for char value

3.float -

Float is used for decimal value

Basically they define what type of data .And then do operation on it.

Variables -

Variable is a word that store value.

Header file-

For example-

#include <stdio.h>

It means that what type of operation

We do and that operation is define in that header file

Terminating semicolons-

; Is mean that statement is end.

Int main( )

Is should be added in every c program.

Size of data type-

Type	Storage size	Value range
char	1 byte	-128 to 127 or 0 to 255
unsigned char	1 byte	0 to 255
signed char	1 byte	-128 to 127
int	2 or 4 bytes	-32,768 to 32,767 or -2,147,483,648 to 2,147,483,647
unsigned int	2 or 4 bytes	0 to 65,535 or 0 to 4,294,967,295
short	2 bytes	-32,768 to 32,767
unsigned short	2 bytes	0 to 65,535
long	4 bytes	-2,147,483,648 to 2,147,483,647
unsigned long	4 bytes	0 to 4,294,967,295

Keywords-

Keywords is that word whose meaning is already define in c .
