Using char*as a key in std::map 在C++中,std::map是一种关联容器,它提供了一种将键值对映射起来的方式。然而,std::map的键类型必须是可比较的,因此使用char*作为键可能会导致一些问题。 char是一个指向字符的指针,它可以用来表示字符串。然而,使用char作为std::map的键存在一些潜在的问题。首先,char是一...
而C++11中:usingUPtrMapSS = std::unique_ptr<std::unordered_map<std::string, std::string>>; 或许从这个例子中,我们是看不出来明显的好处的(而于我来说,以一个第三者的角度,这个例子也难以说服我一定要用C++11的using)。 再来看下: typedefvoid(*FP)(int,conststd::string&); 若不是特别熟悉函数指针...
