Description : The map::find() is a function which returns an iterator through which the key and value pair can be accessed. If not found the iterator returns map.end()
Example :
// Demonstrates find()
#include <iostream>
#include <map>
int main() {
// declaration of map container
std::map<int, int> mymap;
mymap[0] = 10;
mymap[1] = 11;
mymap[2] = 12;
mymap[3] = 13;
// using find() function
auto itr = mymap.find(1);
std::cout << "The value at position " << itr->first << " is " << itr->second << "\n";
return 0;
}
