Question

我似乎无法编译我的代码 - 这是我得到的错误：

6 \ problem11.cpp（21）：错误C2660：'calcScore'：函数不带0参数

解决此问题的任何帮助或建议？这是一个家庭作业问题，我似乎无法弄清楚如何修复错误。我们暂时不允许使用数组。

#include <iostream>

using namespace std;

void getJudgeData(int);
void calcScore(float, float, float, float, float);
float findHighest(float, float, float, float, float);
float findLowest(float, float, float, float, float);

        getJudgeData(3);
        getJudgeData(4);
        getJudgeData(5);
        calcScore();

        system("pause");
        return 0;
    }

    void getJudgeData(int jnumber)
{
    float score1, score2, score3, score4, score5;

    switch(jnumber)

        return;
}

float findHighest(float high1, float high2, float high3, float high4, float high5) // find highest score 
{
    float high = 10;

        if (high1 > high)
        {
             high1 = high;

        else if ( high2 > high)

Answer 1

你有一行

calcScore();

但是函数需要参数（如在代码的其余部分中声明和定义的那样）。

添加参数！

Answer 2

calcScore();

你不能这样做，因为该函数需要4个参数，正如编译器所说。

让我看看我是否明白你想做什么。进行这些更改

float getJudgeData(int jnumber) //return the score
{
    float score; // only one score neeeded

    ...
    //calcScore(score1, score2, score3, score4, score5);
}

您可以删除自

以来的最后calcScore行

a）无论如何都不会到达，它是在交换机内的休息声明之后 b）此时你将获得一个分数。

int main()
{
    float score1, score2, score3, score4, score5;
    score1=getJudgeData(1);
    score2=getJudgeData(2);
    score3=getJudgeData(3);
    score4=getJudgeData(4);
    score5=getJudgeData(5);
    calcScore(score1, score2, score3, score4, score5);
    ...
}

这可能只是做你想要的 - 获取每个浮动，并在它们上面调用calcScore。
