运行策划程序时出现Cygwin错误

Cygwin Error When Running Mastermind Program

本文关键字：Cygwin 错误 程序 运行      更新时间：2023-10-16

我正试图为我的编程类编写一个程序，该程序成功运行一个以数字1-6作为输入而不是颜色的游戏。当我尝试测试程序时，我得到消息

" 0 [main] Lab16 9828 cygwin_exception::open_stackdumpfile: dump stack trace to Lab16.exe.stackdump"

注释掉部分代码似乎没有多大帮助。我对这一切都是新手，所以任何经验教训都很感激。

任何帮助/建议都是非常感谢的!谢谢你阅读我的问题!

当您默认初始化它们时，假设所有向量都有四个元素。vector的默认初始化产生零元素的vector，因此当您访问vector的第一个到第四个元素时，就超出了vector的边界。

这是我正在谈论的一个简短的例子:

std::vector<int> myvector;
myvector[1] = 3; // oh no!

您有三个选项来修复此问题。也可以预先定义vector的大小:

std::vector<int> myvector(4);
myvector[1] = 3; // ok

或者您可以在填充时将其更改为适当的大小:

std::vector<int> myvector; // elsewhere
myvector.resize(4);
myvector[1] = 3; // okay

或者你可以在填充数组时动态调整数组的大小:

std::vector<int> myvector; // elsewhere
for(size_t index = 0; index < 4; ++index){
    myvector.push_back(someNumber); // also okay
}

使用所有的语法，一旦您填充了向量，您就可以使用operator[]以您期望的方式访问元素。只是要确保不要超过向量的边界!您可以像这样调用size来检查向量有多大:myvector.size();
