程序停止而不运行while循环

我的while循环不起作用。该代码可在Codecademy website编译器上正确运行。然后,我用Visual Studio对其进行编译,在命令提示符下运行它并输入一个数字。即使号码正确,程序也会过早停止。

#include <cstdlib>
#include <iostream>

int main() {

  int answer = 8;
  int guess; 
  int tries;

  std::cout << "I have a number between 1-10.\n";
  std::cout << "Please guess it: ";

  std::cin >> guess;  

   while (guess != 8 && tries < 50) {    
    std::cout << "Wrong guess, try again: ";
    std::cin >> guess;   
    tries++;
  }
   if (guess == 8) {   
    std::cout << "You got it!\n";
  }  
}

正如@rsjaffe和@Ken White在评论中所说,android.widget变量已单位化,这意味着该变量指向的内存位置为“垃圾”(留在内存中)。尝试给它一个初始值,就像这样:

tries

它将实例化并初始化int tries = 0; 变量。
