C++ Program to calculate a²-b².

Let see the program to calculate a²-b².

Example:
To calculate a2-b2.
Formula: a2-b2=(a-b)*(a+b).
Declare two variables they are integer data types a, b, and store 

the result in the result then declares an int data type.
Declare one int data type and one float datatype, then store float data type.
Declare two float data type, then store float data type.
Declare two integer data types, then store int data type or float data type.
Input a=2,b=3
Then result=(a-b)(a+b)
a2-b2 two numbers result =-5

#include <iostream>

using namespace std;
int main()
{
    int a,b,result;
    cout<<"Enter a value :";
    cin>>a;
    cout<<"Enter b value :";
    cin>>b;
    result=(a-b)*(a+b);
    cout<<" a^2-b^2 of two numbers :"<<result<<endl;
    return 0;
}

Output:

Enter a value :2
 Enter b value :3
 a^2+b^2 of two numbers:-5
