我正在尝试创建一个程序,用户可以输入多达100个玩家的名字和分数,然后打印出所有玩家的名字和分数,然后输入平均得分,最后,显示球员的得分低于平均水平。除了最后一部分,我已经设法做到了所有这些,显示低于平均分数。我不确定如何去做。在我的DesplayBelowAverage函数中,我试图让它读取当前玩家的分数并将其与平均值进行比较,以查看是否应将其打印为低于平均值的分数,但它似乎无法识别我创建的averageScore值在CalculateAverageScores函数中。这里是我的代码:在玩家得分程序中显示低于平均分数
#include <iostream>
#include <string>
using namespace std;
int InputData(string [], int [], int);
int CalculateAverageScores(int [], int);
void DisplayPlayerData(string [], int [], int);
void DisplayBelowAverage(string [], int [], int);
void main()
{
string playerNames[100];
int scores[100];
int sizeOfArray = sizeof(scores);
int sizeOfEachElement = sizeof(scores[0]);
int numberOfElements = sizeOfArray/sizeOfEachElement;
cout << numberOfElements << endl;
int numberEntered = InputData(playerNames, scores, numberOfElements);
DisplayPlayerData(playerNames, scores, numberEntered);
CalculateAverageScores(scores, numberEntered);
cin.ignore();
cin.get();
}
int InputData(string playerNames[], int scores[], int size)
{
int index;
for (index = 0; index < size; index++)
{
cout << "Enter Player Name (Q to quit): ";
getline(cin, playerNames[index]);
if (playerNames[index] == "Q")
{
break;
}
cout << "Enter score for " << playerNames[index] << ": ";
cin >> scores[index];
cin.ignore();
}
return index;
}
void DisplayPlayerData(string playerNames[], int scores[], int size)
{
int index;
cout << "Name Score" << endl;
for (index = 0; index < size; index++)
{
cout << playerNames[index] << " " << scores[index] << endl;
}
}
int CalculateAverageScores(int scores[], int size)
{
int index;
int totalScore = 0;
int averageScore = 0;
for (index = 0; index < size; index++)
{
totalScore = (totalScore + scores[index]);
}
averageScore = totalScore/size;
cout << "Average Score: " << averageScore;
return index;
}
void DisplayBelowAverage(string playerNames[], int scores[], int size)
{
int index;
cout << "Players who scored below average" << endl;
cout << "Name Score" << endl;
for (index = 0; index < size; index++)
{
if(scores[index] < averageScore)
{
cout << playerNames[index] << " " << scores[index] << endl;
}
}
}
是的,这个工作。感谢您的帮助。 – jackofblaze
