C++ Numbers: Exercise-33 with Solution

Write a program in C++ to display first 10 Fermat numbers.

Sample Solution:

C++ Code :

# include <iostream>
# include <math.h>
using namespace std;
int main()
{
    int n=0;
	double result;
 cout << "\n\n Display first 10 Fermat numbers:\n";
 cout << "-------------------------------------\n";
cout << " The first 10 Fermat numbers are: "<<endl;
while (n <= 10) 
		{
            result= pow(2, pow(2, n)) + 1;
            n++;
            cout << result << endl;
        }
}

Sample Output:

 Display first 10 Fermat numbers:                                      
-------------------------------------
