C++ for loop using for auto

//I think this is a better way for a for loop
//for like going through arrays or something
//hope you like it :)
//be sure to do #include <set>
int main()
{
  set<char> letters = {'A', 'B', 'C'};
  for (auto itr = letters.begin(); itr != letters.end(); ++itr){
    cout << *itr << endl;
  }
}

c++ auto

//When using auto variables, the data type is decided in initialisation

#include <iostream>
using namespace std;

int main() {
    auto IntegerVar=25;   //creates integer type variable
    auto FloatVar=26.77;  //creates float type variable
    auto StringVar="Hello";  //creates string type variable
    auto CharVar="C";   //creates char type variable
  
    cout<<"CREATING VARIABLES USING AUTO DATA TYPE

";
    cout<<"Integer: "<<IntegerVar<<endl;
    cout<<"Float: "<<FloatVar<<endl;
    cout<<"String: "<<StringVar<<endl;
    cout<<"Char: "<<CharVar;
    
    cout<<"

";
    return 0;
}

auto in c++

int foo = 0;
auto bar = foo;  // the same as: int bar = foo; 
// type of bar is the type of the value used to initialize it

for auto c++

for (auto&& [first,second] : mymap) {
    // use first and second
}

c++ auto loop

for(auto x: myVector){
	cout<< x << " ";
}
