Error: 找不到类型,或者它不是编译时常数: Vector. 或者Type was not found or was not a compile-time constant: Vector. 搞了好一会,以为是flex版本的问题. sdk3.2换成了3.5了, 还是一样的... 这 是因为编译时,默认支持的Flash Player的版本是9.0.124.遇到这种错误时,需要修改flex-sdk/frameworks/flex-config.xml, 将<target-
std::vector是我在标准库中实用最频繁的容器.总结一下在遍历和创建vector时需要注意的一些地方. 在不考虑线程安全问题的前提下,在C++11中有五种遍历方式. 方式一 for (size_t i =0; i < vec.size(); i ++) { int d = vec[i]; } 方式二 size_t len = vec.size(); for (size_t i =0; i < len; i ++) { int d = vec[i]; } 方式三 for (auto it
