cpp auto

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

#include <iostream>
using namespace std;

int main() {

    auto FloatVar=26.77;  //creates float type variable
    auto StringVar="Hello";  //creates string type variable
    auto CharVar="C";   //creates char type variable
