COMPRO1 Hands-on Exam (Set A) - Answer Key

Problem:

Write a program to require an integer input between 1 to 10. Vary and display the control variable of a for-loop statement from 1 to 10 and put a dollar sign ($) in place of that number.

Sample Output #1:
Enter a number between 1 and 10: 6
$$$$$6$$$$

Sample Output #2:
Enter a number between 1 and 10: 2
$2$$$$$$$$

Sample Output #3:
Enter a number between 1 and 10: 9
$$$$$$$$9$

Solution:

 #include <iostream>
using namespace std;

int main(){
  int n;

   cout << "Enter a number between 1 and 10: "
   cin >> n;
  for (int i=1; i<=10; i++)
   {
        if (n==i)
            cout << "$";
       else
           cout << i;

   }

   return 0;
}
