我对如何在C++中检查输入变量的数据类型有一个疑问.

#include<iostream>
using namespace std;
int main()
{
    double a,b;
    cout<<"Enter two double values";
    cin>>a>>b;
    if()        //if condition false then
        cout<<"data entered is not of double type"; 
        //I'm having trouble for identifying whether data
        //is double or not how to check please help me 
}
