Question

你好我在尝试将一些变量输出到屏幕时得到负值。

我看了这个，在大多数情况下它是一个未初始化的变量，但我找不到任何错误。

说我有太多的代码到文本比例，但我真的不知道如何重申，所以继承人有些填充。

#include <iostream>
#include <string>

using namespace std;


int main()
{

    int Input;
    int WepType;
    string Weapon;
    string WeaponType;

    int Stats[3];
    int AtkStats[4];


cout << "Pick your weapon.\n" << endl;
cout << "{===================================================}\n";
cout << "[                                                   ]\n";
cout << "[  Iron Longsword              Sharp Fishing Spear  ]\n";
cout << "[         1                                         ]\n";           
cout << "[                                                   ]\n";     
cout << "[              Ornate Hunting Bow                   ]\n";
cout << "[                                                   ]\n";
cout << "{===================================================}\n";

//Weapon Selection
 cin >> Input;

    if(Input == 1)
    {
     WepType     = 1;
     Weapon      = "Iron Longsword";
     WeaponType  = "OneHanded";
     Stats[0]    = Stats[0] + 10;
     Stats[1]    = Stats[1] + 0;
     Stats[2]    = Stats[2] + 0;
     AtkStats[0] = AtkStats[0] + 10;
     AtkStats[1] = AtkStats[1] + 0;
     AtkStats[2] = AtkStats[2] + 0;
     AtkStats[3] = AtkStats[3] + 0;


    cout << "Weapon      = " << Weapon      << endl;
    cout << "Weapon Type = " << WeaponType  << endl;
    cout << "Health      = " << Stats[0]    << endl;
    cout << "Physical    = " << AtkStats[0] << endl;
    cout << "Light       = " << AtkStats[1] << endl;
    cout << "Dark        = " << AtkStats[2] << endl;
    cout << "Temporal    = " << AtkStats[3] << endl;
    }



      return 0;
    }

问题在于：

int Stats[3];
int AtkStats[4];

你应该这样做：

int Stats[3] = {0, 0, 0};
int AtkStats[4] = {0, 0, 0, 0};

或者正如BlastFurnace在评论中指出的那样（我忘了）：

int Stats[3] = {}; // Initialize all elements to zero.
int AtkStats[4] = {};

为了初始化值。现在它们只是随机垃圾，所以当你分配时，你会得到错误。
