**************
This coding is solely of my logic. Here I face problem of updating the current date. I would be thankful if you have any suggestions for that or for anything that I could improve.
Thanks.

Code in C++ to find difference,product,quotient and remainder of two numbers

I suggest all of you to read the below code. These four operations can easily be performed by using the correct operator(i.e, + , - , * , / , %)etc.

To find the difference,    change     s=a-b;
To find the product,        change      s=a*b;
To find the quotient,       change       s=a/b;
To find the remainder,    change        s=a%b;

NOTE: These statements should only be used in the place of s=a+b; . And don't use all of these operations at once or if you want to print all the operations at once , give s=a+b;k=a-b;
etc... i.e, assign these operations to different variables and print them respectively.

Code in C++ to find the sum of two numbers

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int a,b,s;
cout<<"\n Enter the first number : ";
cin>>a;
cout<<"\n Enter the second number : ";
cin>>b;
s=a+b;
cout<<"\n The sum is : "<<s;
getch();
}
