#include#include #include #include "nf_share_ptr.h" // package library using namespace std; int main() { vector v{ 1, 2, 3, 4, 5 }; NF_SHARE_PTR sp = GetElement(v, 2); if (sp) cout << *sp << endl; // output: 3 return 0; }
#includeIn the above example, we have a map of string and integer key-value pairs, and we are using the GetElement function to get the value of the key "banana" by passing the map and the key to the function. The function returns a shared pointer to the value, which we are dereferencing to get the value of the key. Based on the syntax of the function and the package library included, it appears that NF_SHARE_PTR is part of the library "NF".#include
