What is a c#'s analog of std::pair in c++? Every make_pair now becomes calling the inline key function. The difference is that with std::pair you need to specify the types of both elements, whereas std::make_pair will create a pair with the type of the elements that are passed to it,.
Provide a generic class pair for representing pairs of. This is easily worked around by defining your hash class outside of namespace std, and using that hash explicitly in. Unordered map does not contain a hash function for a pair, so if we want to hash a pair then we have to explicitly provide it with a hash function that can hash a pair.
This is a question about the interpretation of the compiler errors (and not a repeat question, as that. Here is my object literal: How can i add field key3 with value3 to the object? Hash<pair<int,int>> depends on primitive and standard library types only.
Just attempting this question i found in a past exam paper so that i can prepare for an upcoming java examination. The main argument is that a class pair doesn't. In a thread on comp.lang.java.help, hunter gratzner gives some arguments against the presence of a pair construct in java. Am i remembering incorrectly, or did java, once upon a time, provide a pair class as part of its api?
