The first problem is you need a cout statement for your 100
1 2 3 4 5 6 7 8
int Count_For_Cal;
int Count_For_Output;
int First_Number = 100;
cout << First_Number << endl; //Like so...
for ( Count_For_Cal = 1; Count_For_Cal <= First_Number ; Count_For_Cal++)
}
//and your other stuff...
The other problem lies in one of your for loops take note that the output you got had an extra value thus suggesting your loop went longer then needed. I am not entirely sure how you worked the logic in these for loops, but my guess the problem is your first for loop due First_Number being constantly changed. I would suggest watching the counter values and ensure they are behaving in the manner you wanted to.
