In C++: By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two; for example, the first 6 Fibonacci numbers are 0, 1, 1, 2, 3, 5. Write a program that asks the user for a number between 5 and 20 (inclusive) and then displays that many Fibonacci numbers. You must use a loop to calculate this! DonA????1t just cout the answer for each of the 15 possible answers. Also: Note that there is no last comma in the list.

Example of runs:

Here's my code so far:

#include <iostream>
#include <cstdlib>
using namespace std;

int main(){
   int x = 0;
   int fibNum = 0;

   cout << "How many Fibonacci numbers do you want? <5 to 20>: ";
   cin >> fibNum;

   while(x <= fibNum){
       x = x +1;
       cout << x << ", ";
   }
  

   return 0;
}

I can't get it to print out: 0, 1, 1, and etc. And I can't get it to not print a ',' at the last number.
