Write a program in C++ to find any number between 1 and n that can be expressed as the sum of two cubes in two (or more) different ways

# include <iostream>
# include <math.h>
using namespace std;
int main()
{
    int a,b,c,d,n;
	double result;
	cout << "\n\n Find the numbers between a range that can be expressed as the sum of two cubes:\n";
	cout << "------------------------------------------------------------------------------------\n";
	cout << " The numbers in the above range are: "<<endl;
         n = 100000;  
        for (int a = 1; a <= n; a++) 
		{  
            int a3 = a*a*a;  
            if (a3 > n) break;  
  
            for (int b = a; b <= n; b++) 
			{  
                int b3 = b*b*b;  
                if (a3 + b3 > n) break;  
  
                 for (int c = a + 1; c <= n; c++)

                    int c3 = c*c*c;  
                    if (c3 > a3 + b3) break;  
  
                    for (int d = c; d <= n; d++)

                    }
