loop through map c++

for (auto i = myMap.begin(); i != myMap.end(); ++i) {
  cout << i->first << ": " << i->second << endl;
  
}

c++ map iterator

#include <iostream>
#include <map>
 
int main() {
  std::map<int, float> num_map;
  // calls a_map.begin() and a_map.end()
  for (auto it = num_map.begin(); it != num_map.end(); ++it) {
    std::cout << it->first << ", " << it->second << '
';
  }
}

cpp map iterate over keys

#include <iostream>
#include <map>

int main()
{
    std::map<std::string, int> myMap;

    myMap["one"] = 1;
    myMap["two"] = 2;
    myMap["three"] = 3;

    for ( const auto &myPair : myMap ) {
        std::cout << myPair.first << "
";
    }
}

c++ iterate map

// C++17 and above
for (auto const& [key, value] : map)
{
  // do something
}

c++ map loop through key value

#include <iostream>
#include <map>

int main() {
    std::map<std::string, int> myMap;

    myMap["one"] = 1;
    myMap["two"] = 2;
    myMap["three"] = 3;

    for ( const auto &[key, value]: myMap ) {
        std::cout << key << '
';
    }
}

c++ iterate map

// C++11 and onwards
for (auto const& keyValue : map)
{
  keyValue.first; // Key
  keyValue.second; // Value
}

iterate through map c++

    for (auto i : m)
        cout << i.first << "   " << i.second
             << endl;

looping in map c++

void output(map<string, int> table)
{
       map<string, int>::iterator it;
       for (it = table.begin(); it != table.end(); it++)
       {
            //How do I access each element?  
       }
}
