 | >#include <getch> [b]If[/b] your compiler supports getch, it will most likely be in conio.h. But because getch is not a standard function, cin.get() is recommended instead: [code] #include <iostream> using namespace std; // Any other headers you need int main() { // Your program here cin.get(); } [/code] This will …  |

| | > while(!cin.eof() ) This is a bad idea and will probably result in you processing the last line of the file twice. A better method is to use your input as the condition: [code] while ( cin >> numGold >> numSilver >> numBronze ) [/code] Without knowing the format of … |

| | Consider your boundary conditions. For each digit, unless the next outer loop is on the last iteration, you want to print 0 through 9. Otherwise you print 0 through the digit value. There isn't a very clean solution; you either use conditional expressions or long and redundant if sequences: [code] … |
