Exercise 1:
#include <iostream>
using namespace std;
int main()
{
cout << "Enter a number N: ";
double n;
cin >> n;
double power=1;
while(power<=n)
{
power*=10;
}
cout << "The first power of ten greater than N is: " << power << endl;
}
Exercise 2:
#include <iostream>
using namespace std;
int main()
{
cout << "Enter a number N: ";
double n;
cin >> n;
double power=1;
while(power<n)
{
cout << power << endl;
power*=10;
}
}
