c++ - 用于 Xcode 4.x 的 CS106B 库

Question

是否有适用于 CS106B 的斯坦福 C++ 库版本可用于 Xcode 4.x。iTunes U 视频已有大约 4 年历史，讲义中提到的库与 Xcode 4.x @ 10.7.3 不兼容。

我已经尝试安装 Xcode 3，但它在启动时崩溃，所以这不是一个选项。

也许那里有一些提供类似功能的等效库？

有什么建议吗？

库在这里可用: http://see.stanford.edu/materials/icspacs106b/CS106Libs_for_Xcode.zip

#include "genlib.h"
#include "simpio.h"
#include <iostream>


int main(int argc, const char * argv[])
{
    // insert code here...
    std::cout << "Hello, World!\n";
    return 0;
}

编译错误:

我遇到了同样的问题。解决这个问题的方法不是下载旧的 XCode(它会崩溃)或更新版本的斯坦福库(它不存在)——首选的方法是使用新的分配文件(每个文件都带有附加的必需库文件)并通过在每个文件夹中打开 xcode 项目文件直接在 XCode 4 中打开这些文件。您可以在当前类(class)网站中找到这些文件: http://www.stanford.edu/class/cs106b/

不幸的是，您无法直接获取这种格式的旧作业文件。鉴于此，您可以 1) 遵循当前类(class)网站上的新练习，或 2) 使用空白项目文件夹并稍微调整以遵循旧作业。
