Question

它一直在说标识符＆＃34; posi＆＃34;由于某种原因未定义，搜索它但发现没有相似之处，任何人都可以帮忙吗？代码如下，我不熟悉编程，而不熟悉c ++，请帮助，谢谢。

#include "stdafx.h"
#include <iostream>
#include <math.h>

using namespace std;

const int num = 10;

int max[num], sum[num], min[num];
int total(int sum[], int num);
int maximum(int max[], int num, int posi[]);
int minimum(int min[], int num, int posi[]);

int main() {
    int i, pnum, psum, pmax, pmin;
    cout << "Give 10 positive integer values, one-by-one: " << endl;
    while (num > 0) {

        for (i = 0; i < 11; i++) {
            cout << "Enter Number" << i << ":";
            cin >> pnum;

        }

    }
    psum = total(sum, num);
    cout << "The sum is " << sum;
    cin >> sum[i];
    pmax = maximum(max, num, posi);
    cout << "The maximum value is " << max << ", and it is in position " << 
    posi << endl;
    cin >> max[i] >> posi[i];
    pmin = minimum(min, num, posi);
    cout << "The minimum value is " << min << ", and it is in position " << 
    posi << endl;
    cin >> min[i] >> posi[i];
    system ("pause");
    return 0;
    }

        int maximum(int max[], int num, int posi[]) {
        int posit = 0, maxi = 0, numb,i;
        maxi = numb;
        while (numb > 0) {
            for (i = 0; i < 11; i++) {
                if (numb > maxi) {
                    maxi = numb;
                    posit = i;

                }
                i = i + 1;
            }
            return maxi;
        }
        }

它说它未定义，因为你从未定义它。在此函数中调用pmax = maximum(max, num, posi);，您将posi传递给最大值，但您还没有定义它！您调用maximum而不是minimum的错误的原因可能是因为编译器在遇到未定义的引用时停止编译。如果您移除了对maximum的来电，那么当您尝试cin >> max[i] >> posi[i];时，它会给您一个错误。如果您删除该行，那么当您致电minimum,时，它会给您一个错误，依此类推。我建议查看一些基本的C ++教程，these ones非常好。特别是Variables and Types部分。
