/* c++ is world popular language you can do every thing with the help of this
but after learning it
today  lecture is on making calcultor but its mini hahahha

c++ have some Arthmetic operator  like + ,- ,*, /, % today i will teach you how
to use these operator in c++*/
#include<iostream>
#include<conio.h>
using namespace std;
main()

{
int r;  // declaring variable of data type int

r=2;    // assigning values to that variable

int b;  //declaring another varaible ;

b=4;    // assigning value to that variable

int sum; // declaring another varaible to hold the sum of the two variables

sum=r+b;  // here i am adding these two variables

cout<<sum;  //here is output of sum variable
}
/* CONCEPT:

you are aware of assigning values to variable but here is another concept
 on line 21 i declare int sum on line 23 the addition of both r and b are assign
 to the sum and at the end sum is out put

 so here a single variable is holding a combination of two variable

 Practise:
 
  write a program to perform the arithmetic operation by using all the operator
  also print result of all these operation
