I have checked out lots of sources from the internet but i cant find the exact way how to do it.
But i do found something like this:
I'm a beginner, not sure about it, but i think that is C++.Code:
#include <iostream>
int main()
{
double d;
cin>>d;
if ( !cin.fail() )
cout<<"Valid data type"<<endl;
else
cout<<"Invalid data type"<<endl;
return 0;
}
Is anyone know how to do it in C? Please help. Thanks in advanced!
