DATA TYPE,VARIABLES,INPUT AND OUTPUT

DATATYPE: C has five types of basic Data.such as int,double,float,char and void.Today we are going to learn int Type data programming.int stand for integer.Integers are 0,1,2,3......

VARIABLES: A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in C has a specific type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable.

The name of a variable can be composed of letters, digits, and the underscore character. It must begin with either a letter or an underscore.Upper and lowercase letters are distinct because C is case-sensitive.

Now write this program on your compiler:

code:

           #include <stdio.h>

           int main()

           {

               int x,y;

               x = 5;

               y = 6;

               printf("%d",x);

           return 0;

           }

Output: 5

Description of the program: Here i wrote int x,y;. int stand for integer and here i declared two variables x & y.You can declare many variables.You can not write variables like 1x,$a,#x,+y,show-ans etc.You can use this operators or signs or numbers (1,$,+,#) after characters.And you can use show_ans.
In printf function i used "%d" for showing integer which i mentioned after it.

Can you do summation,subtraction,multiplication and division by C?See in my next post.
