针对你遇到的问题“no template named 'vector' in namespace 'std'”,这里有几个可能的解决步骤和检查点,帮助你定位并解决问题: 检查头文件包含: 确保你的代码中包含了正确的头文件<vector>。这个头文件是C++标准模板库(STL)的一部分,提供了std::vector容器的定义。示例代码如下: cpp #include <ve...

I am writing some simple shader compilation code and during one point I use a vector of chars to store an error log if things go wrong. The problem is of course that the compiler refuses to accept that vector is in std:: (this is a probl...

在编程语言中,命名空间是一种特殊的作用域,它包含了处于该作用域中的所有标示符,而且其本身也是由标示符表示的。命名空间的使用目的是为了将逻辑相关的标示符限定在一起,组成相应的命名空间,可使整个系统更加模块化,最重要的是它可以防止命名冲突。就好比在两个函数或类中定义相同名字的对象一样,利用作用域标示符...
