Variable And INT

#include<iostream>     // it is  a library used for display
#include<conio.h>      // its is also a library used for input output statement
using namespace std;

main()

{
int a;  
                        /* what is (int) here and what is (a) here
                   the two question which was in mind of me
                   when i was in first semester*/
                 

}

/* Here there are two thing

2) int

1) a:
is basically a Variable which represent a storage or memory in computer

like if we define (int a) then a memory is located in computer to store
the value of a
it can be changed during execution of program but i will define it later

2) int

2) INT :
int basically specifies the type of data that can be stord
in it Each variable is declared by its types
like
i)int =  can hold integers like 22 is an integer so it will be good to
store it in (int)

ii) float= can store float values like 22.5 22.1 or every float value

iii) char = can store character like A to Z values
 There are 5 data type but main are above
 Hope this question will not be ariesed in your mind now
