所以我的项目是用 C++ 制作一个基于文本的杆位游戏。我的柜台似乎没有工作。它只会增加，但永远不会退缩。现在我只担心左右移动。这是我的代码：

void move(){
system("cls");
    //movement testing
char move = 'l'; 

int posX = 10;
int posY = 0;
int counter = 1;

while (true){

 if (move == 'l')
    counter = counter +1;

 else if (move == 'j')
    counter = counter -1;

 if (counter = 0){
 counter = 0;
  cout <<endl;
 cout <<endl;

 cout <<"   |       [IS A CAR] "<< endl;
 cout <<"   |      O||[]___[]||O "<< endl;
 cout <<"_______________________________________________________________________________" <<endl;
 cout << "Current Position = [" << posX << ","<<posY << "] <Enter a move>";
 cin >> move;
 }



   if (counter = 1){
 system("cls");

像这样的行if (counter = 0)会将计数器设置为零，而不是测试它是否为零。你需要if (counter == 0)改用。

更一般的评论是，你永远不应该有这么多重复的源代码 - 你可以使用一个循环来摆脱所有这些空白 line couts，然后有另一个循环来生成间距以将汽车侧向移动。
