C++ Program to calculate a³ + b³.

Let see the program to calculate a³ + b³.

Example:

To calculate a3 + b3.
Formula: a3 + b3 = (a + b)(a2 - ab + b2) 
Input a=1,b=2
a3 + b3 =9

#include <iostream>

using namespace std;
int main(void)
{
    int a,b,result;
    cout<<"Enter a value :";
    cin>>a;
    cout<<"Enter b value :";
    cin>>b;
    result= (a+b)*(a*a- a*b + b*b) ;
    cout<<" Result a^3 + b^3 = :"<<result<<endl;
    return 0;
}

Output:

 Enter a value :2
 Enter b value :3

 Result a^3 + b^3 = :35

/* C++ Program to calculate a3+ba3 using pow() function. */
#include <iostream>

using namespace std;
#include <math.h>
int main(void)
{
    int a,b,result;
    cout<<"Enter a value :";
    cin>>a;
    cout<<"Enter b value :";
    cin>>b;
    result= (a+b)*(pow(a,2)- a*b + pow(b,2)) ;
    cout<<" Result a^3 + b^3 = :"<<result<<endl;
    return 0;
}

Output:

 Enter a value :3
 Enter b value :4

 Result a^3 + b^3 = :91
