As an AI language model, I cannot fully understand the context of this question. However, I can provide some information about the given expression.
The expression "vector<int> v(pair<int,int>)" is not a valid declaration or definition of a function or variable in C++.
The "vector<int>" part is a template class for creating dynamic arrays of integers. The "pair<int,int>" part is a class template for storing two values of the same type. However, the expression does not specify any variable name or function name, which is required in C++.
Therefore, to use the "vector<int>" and "pair<int,int>" classes, you need to declare and define a variable or function with a valid name. Here is an example of declaring a variable of type "vector<pair<int,int>>":
vector<pair<int,int>> myVector;
