Question

c++新手编程问题，，求解决，，

#include <iostream>
#include <string>
#include <ctime>

#include <cstdlib>
enum Faces { ONE = 1, TWO, THREE, FOUR, FIVE, SIX };

int frequency1;
int frequency2;
int frequency3;
int frequency4;
int frequency5;
int frequency6;
int total;

void setFrequency( int face );
int rollDie();

int main()
{
int numberOfRolls;
int die1;
int die2;

srand( time( 0 ) );

cout << "\nEnter the number of times to roll the dice: ";
cin >> numberOfRolls;

for ( int i = 0; i < numberOfRolls; i++ )
{
die1 = rollDie();
setFrequency( die1 );
die2 = rollDie();
setFrequency( die2 );

cout << "\nRoll " << i + 1 << endl;
cout << "---------" << endl;
cout << "Die 1:\tDie 2:" << endl;
cout << die1 << "\t" << die2 << endl;
}

total=numberOfRolls*2;

cout << "\nStatistical information:" << endl;
cout << "Frequency for side one: " << frequency1 << endl;
cout << "Frequency for side two: " << frequency2 << endl;
cout << "Frequency for side three: " << frequency3 << endl;
cout << "Frequency for side four: " << frequency4 << endl;
cout << "Frequency for side five: " << frequency5 << endl;
cout << "Frequency for side six: " << frequency6 << endl;
cout << "Total dice rolled: " << total << endl;

cout << "\n"; /
system("pause");

return 0; /

} //

int rollDice()
{
int face;
face=1+rand()%6;
return face;
}

void setFrequency (int face)
{
switch ( face )
{
case ONE:
frequency1++;
break;

case TWO:
frequency2++;
break;

case THREE:
frequency3++;
break;

case FOUR:
frequency4++;
break;

case FIVE:
frequency5++;
break;

case SIX:
frequency6++;
break;
}
}

Answer 1

int rollDie(); 和 int rollDice()
前后写错了！
