    scale(Dist &d1, float scalefactor)
    {
        d1.feet= d1.feet*scalefactor;
        d1.inches=d1.inches*scalefactor;
        while(d1.inches>=12)
            {
                d1.inches=12-d1.inches;
                d1.feet++;
            }

};
main()
{
    Dist d1,d2;
    d1.enter();
    d1.scale(d1,0.5);
    d1.display();

} //error is in this line

What I have tried:

I tried to look for any syntax error and commented the whole main function but the error is still there.

You are missing a close curly bracket (and have a spurious semicolon before main
If you sort your indentation out, it becomes more obvious:

C++

class Dist
{
    int feet;
    float inches;
public:
    enter()
    {
       ...
    }
    display()
    {
       ...
    }
    scale(Dist &d1, float scalefactor)
    {
       ...
       while(d1.inches>=12)
       {
          ...
       }
    }
main()
    {
       ...
    }
--- requires a close curly bracket here to end the class definition ---

Solution 3

Well, at a glance, the 'scale' method in the 'Dist' class does not have a closing '}'. Sometimes compiler errors are a bit mysterious and other times, they mean exactly what they say. It is up to you to figure out the difference.

Solution 2

In addition to OG's answer, I think

C++

d1.inches=12-d1.inches;

should read

C++

d1.inches -= 12;

instead.
