Example 2: how to check the datatype of a variable in c++

#include <iostream>
class someClass { };
int main(int argc, char* argv[]) {
int a;
someClass b;
std::cout<<"a is of type: "<<typeid(a).name()<<std::endl;
// Output 'a is of type int'
std::cout<<"b is of type: "<<typeid(b).name()<<std::endl;
// Output 'b is of type someClass'
return 0;
// on the online compiler it comes as 'i' for int and 'c' for char
