BASICS OF C

Basics of C.

C language consists of datatypes, variables and constants.

Datatypes are those which hold some values during the execution of program. 

For eg. int . int is the datatype which can hold integer values.

Float . it is the datatype which hold the fractional value.

Char is the datatype which can hold the characters.

.

And the most important thing is C is a case sensitive language.

int and Int both have different meanings.

some examples of datatype are .

here is a little illustration of such datatype in C program.

#include<stdio.h>

void main()

{ int a=1;

float b=0.0f;

char c='a';

printf("%d%f%c", a,b,c);

} 

At the top these are header files which contain function printf which is being used in this program.

 The out of the program will be 10.0a.
