C++ STL | Copy one vector to another by using vector.assign() function: Here, we are going to learn how to copy one vector to another by using vector.assign() function? Submitted by IncludeHelp, on September 27, 2018 Problem statementGiven a vector and we have to assign copy it to ...
The third member function replaces the controlled sequence with the sequence designated by the enumerator right. You use it to make the controlled sequence a copy of a sequence described by an enumerator. Example 複製 // cliext_vector_assign.cpp // compile with: /clr #include <cliext/vector>...
Question #1 from Page 366: Suppose there is a reduction in aggregate real money demand, that is, a negative shift in the aggregate real money demand function. Trace the short-run and long-run effects on the exchange rate, interest rate, and price level. Answer: A reduction in real money...
