3.17.2.Use do while loop to read a number

#include <iostream> 

using namespace std; 

 

int main() 

{ 

  int num; 

 

  do { 

    cout << "Enter a number (100 to stop): "; 

    cin >> num; 

  } while(num != 100); 

 

  return 0; 

}

Enter a number (100 to stop): 1
Enter a number (100 to stop): 2
Enter a number (100 to stop): 3
Enter a number (100 to stop): 100
