谢谢楼上的

#include<iostream>
using namespace std ;
int  main()
{
        for(float x=0; x<=1.0; x=x+0.1)
             cout<<x<<\",\";
        cout<<endl;
        bool m = (x<=1.0) ;
        cout << \"x = \" << x << endl ;
        cout.setf(ios_base::boolalpha) ;
        cout << \"x<=1.0 \" << m << endl ;
        bool n = (1<=1.0);
        cout << \"1<=1.0 \" << n << endl ;
        return 0 ;
}
