Question

我一直在查看我的代码一段时间了，我无法弄清楚为什么这个错误会不断出现。它可能非常简单，但我无法理解......

“program.exe中0x00FB59E6处的未处理异常：0xC0000005：访问冲突写入位置0x00000009。”

这是在第三次重复程序时发生的

的main.cpp

#include <iostream>
#include <string>
#include "functions.h"

using namespace std;

int main(){
    RandomArray();
    MinMaxArray();
    SortedArrays();

    cout << "\n\nWould you like to re-run? (Y/N): ";
    cin >> y;

    if (y == "Y" || y == "y"){
        system("CLS");
        main();
    }else{
        system("PAUSE");
    }

  return 0;
}

functions.h

#include <iostream>
#include <time.h>

using namespace std;

int array[50], used[50], sortedArray[50];
int buildSort = 1, genNum, mx = 0, mn = 100;
bool x;
string y;

int RandomArray(){
    srand(time(0));
    for(int a = 0; a < 50; a++){ //array generator
        do{
            genNum = (1+rand()%100); //generate a # between 1-100
            x = false;
    for(int b = 0; b < 50; b++){
        if(genNum == used[b]){ //if the number is already used...
            x = true; 
       }
    }

    }while(x == true);
        used[a] = genNum;
        array[a] = genNum;
    }

    cout << "Random array: " << endl;

    for(int c = 0; c < 50; c++){
        cout << array[c] << " "; //display the random array
    }
    cout << endl << endl;
    return 0;
}

int MinMaxArray(){
    for(int d = 0; d < 50; d++){ //for each number in the array
        if(array[d] > mx){ //check to see if each number is greater than mx
            mx = array[d]; //the max equals that number it picked out
        }
        if(array[d] < mn){ //check to see if theres a number is less than mn
            mn = array[d]; //the minimum equals that number it picked out
        }
    }

    cout << "Maximum: " << mx << endl; //display the max
    cout << "Minimum: " << mn << endl << endl; //display the min
    return 0;
}

int SortedArrays(){
    sortedArray[0] = mn;
    for(int e = mn + 1; e <= mx; e++){ //goes through 1-100 and adds each number to another array in order
        for(int f = 0; f < 50; f++){
            if(array[f] == e){
                sortedArray[buildSort] = array[f];
                buildSort++;
            }
        }
    }

    cout << "Sorted array: " << endl;
    for(int g = 0; g < 50; g++){
        cout << sortedArray[g] << " "; //display sorted from lowest to highest
    }

    cout << endl << endl;
    cout << "Reverse sorted: " << endl;

    for(int h = 49; h >= 0; h--){
        cout << sortedArray[h] << " "; //display sorted from highest to lowest
    }
    return 0;
}

Answer 1

您正在使用第一次初始化的一些变量：buildSort，mx和mn; 在主要开头添加类似

的内容

int main()
{
    buildSort = 1;
    mx = 0;
    mn = 100;

    RandomArray();
    MinMaxArray();
    SortedArrays();
}

再试一次。您的buildSort会让您耗尽阵列。

只是一个建议：尝试更好地编写代码！几乎不可读!!!

Answer 2

不要使用全局变量（至少不是这样！）
您无需使用system功能来处理CLS和PAUSE等基本功能，您可以使用clrscr()或getch()（或相应的功能）
不要递归main - 这不是为了这个目的。虽然没有编译器会抱怨，但这是不好的方法。
