堆栈被损坏

Question

我有一个循环，直到经修正Y的功能，正回答类型，但在选择结束时，我得到的错误：

Time Check Failure #2 - Stack around the variable 'YESNO' was corrupted. 

香港专业教育学院对谷歌一看，着真的找到任何relivent回答这个错误我的代码如下：

void Mesh_equations(float a,float b,float c,float d,float e,float f){ 

    char YESNO[1];                     //define variables. 
    int loop=0;                     //loop set to zero. 
    while(loop==0){                    //while loop initiated whilst loop is equal to zero. 
    cout <<"\nDo you want to display your coefficients for the mesh equations...(y/n)?"; 
    cin>>YESNO;                     //prompt and cin. 
    if (YESNO[0] == 'Y' || YESNO[0] == 'y'){               //if cin is 'Y' or 'y' 
     system("CLS"); 
     cout<<"Loop One:\n(" <<a <<")" <<"Ix + (" <<b <<")" <<"Iy = (" <<e <<")" <<endl 
      <<"Loop Two:\n(" <<c <<")" <<"Ix + (" <<d <<")" <<"Iy = (" <<f <<")" <<endl<<endl 
      <<setw(5)<<" Where ;\n" 
      <<setw(5)<<"A ="<<a<<endl 
      <<setw(5)<<"B ="<<b<<endl 
      <<setw(5)<<"C ="<<c<<endl 
      <<setw(5)<<"D ="<<d<<endl 
      <<setw(5)<<"E ="<<e<<endl               ////set the field width to 5 characters. 
      <<setw(5)<<"F ="<<f <<endl<<endl;             //display. 
     loop=1;                     //loop is 1, while loop passed. 
     system("pause"); 
    } 
    else if(YESNO[0] == 'N' || YESNO[0] == 'n'){              //if 'N' or 'n', while loop passed. 
    loop=1; 
    } 
    else{                      //if neither y or n is enterred input must be incorrect. 
    cout <<"bad answer, try again\n"; 
    Beep (600,100); 
    loop=0;                      //loop is zero, while loop continues. 
    } 
} 
}

Answer 1

发生这种情况是因为YESNO是一个字符数组，而cin >> YESNO;正在向此数组写入NULL终止符。

将YESNO的声明更改为char YESNO;，并删除数组运算符，并且您很好。

Answer 2

使YESNO变大，即10个字符而不是1.空字符放在数组中的最后一个允许位置之后，这是错误的原因。

Answer 3

如果数组元素被分配到数组的边界之外，那么在运行时会显示消息“堆栈变量已损坏”。因此，要解决此问题，请确保分配的数组大小和分配给它的值。
