std in class Distance does not name a type

Jaif (9)
Hello,

I am getting error:'std' in 'class Distance' does not name a type... and if I use "using namespace std;" in both header and cpp file it will put out error:ostream in class Distance does not name a type.

In .cpp line 87 there error is happening

Is there any fix for this?

Remove Distance:: from line 87.

 
 
Distance::std::ostream& operator<<( std::ostream &os, const Distance& d){

If I do so, I get all these error's:


86 error: 'get_judze' was not declared in this scope|

87 error: 'get_jardi' was not declared in this scope|

98 error: 'get_peda' was not declared in this scope|

|89| error: cannot bind 'std::ostream {aka std::basic_ostream<char>}' lvalue to 'std::basic_ostream<char>&&'|

|96| error: cannot bind 'std::ostream {aka std::basic_ostream<char>}' lvalue to 'std::basic_ostream<char>&&'|

|101| error: cannot bind 'std::ostream {aka std::basic_ostream<char>}' lvalue to 'std::basic_ostream<char>&&'|

It's because you forgot to use the Distance object d when calling the functions. You also need to put parentheses after the function names.

if(d.get_judze() == 0){

That's right. Function in total should be:

std::ostream& operator<<( std::ostream &os, const Distance& d)
{
    if(d.get_judze() == 0)
    {
        if(d.get_jardi() == 0)
        {
            if(d.get_peda() == 0)
            {
                os << d.get_colla();
            }
            else
            {
                os << d.get_peda() << "’" << d.get_colla() << "”";
            }
        }
        else
        {
            os << d.get_jardi() << "y" << d.get_peda() << "’" << d.get_colla() << "”";
        }
    }
    
    else
