我写了个简单的求平均数的程序,调试的时候弹出一个错误提示,选择忽略可以继续运行
...个人估计是32行      delete [] ptemp;有问题,内存上的错,但是不知但改怎样,修改.
请大家帮忙,谢谢
#include <iostream>
#include <iomanip>

using std::cout;
using std::cin;
using std::endl;
using std::setw;

int main()
{
    int arraySize = 5;
    int count = 0;
    double value = 0.0;
    double* pvalueBox = new double[arraySize];
    double* ptemp;

    for(;;)
    {
        cout << endl << "Please input a value or enter 0 to end." << endl;
        cin >> value;
        if (value == 0)
            break;
        if (count > arraySize)
        {
            arraySize += 5;
            ptemp = pvalueBox;
            pvalueBox = new double[arraySize];
            for (int i = 0; i < count; i++)
                pvalueBox[i] = ptemp[i];
            delete [] ptemp;
        }
        pvalueBox[count] = value;
        count++;
    }
    
    double sum = 0;
    for(int i = 0; i < count; i++)
    {
        sum += pvalueBox[i];
        cout << setw(9) << pvalueBox[i];
        if ((i+1)%5 == 0)
            cout << endl;
    }

    cout << endl << "The average is " << setw(10) << (sum/(count)) << endl;

    return 0;
}

顶下,希望有人解答.

if (count >= arraySize)

#include <iostream>
#include <iomanip>

using std::cout;
using std::cin;
using std::endl;
using std::setw;

int main()
{
    int arraySize = 5;
    int count = 0;
    double value = 0.0;
    double* pvalueBox = new double[arraySize];
    double* ptemp;

    for(;;)
    {
        cout << endl << "Please input a value or enter 0 to end." << endl;
        cin >> value;
        if (value == 0)
            break;
        if (count >arraySize-1)
        {
            arraySize += 5;
            ptemp = pvalueBox;
            pvalueBox = new double[arraySize];
            for (int i = 0; i < count; i++)
                pvalueBox[i] = ptemp[i];
            delete [] ptemp;
        }
        pvalueBox[count] = value;
        count++;
    }
   
    double sum = 0;
    for(int i = 0; i < count; i++)
    {
        sum += pvalueBox[i];
        cout << setw(9) << pvalueBox[i];
        if ((i+1)%5 == 0)
            cout << endl;
    }

    cout << endl << "The average is " << setw(10) << (sum/(count)) << endl;

    return 0;
}数组越界了..和删除没什么问题

哦,谢谢ls的白兔..按你说的解决了

同时也谢谢红头发的帅哥..

要是没掉线就好了...被疯子崇拜者抢了先....哎...
