    You don't need cin>>fullname and getline(cin,fullname). Try -

    Code:
    #include <iostream> 
    #include <string> 
    
    using namespace std; 
    int main () 
    { 
    string fullname; 
    
    cout<< "Please enter you first and last name:"; 
    
    getline(cin,fullname,'\n'); 
    
    int spaceposition; 
    
    spaceposition= fullname.find(" ",0); 
    
    string fname; 
    
    fname=fullname.substr(0,spaceposition); 
    
    string lname; 
    
    lname=fullname.substr(spaceposition,fullname.size()); 
    
    cout << "First Name: "<<fname<< endl; 
    cout << "Last Name: " <<lname<< endl; 
    
    return 0; 
    }
