Language bug

A bug in user code is not a bug: the InitIndicators(CIndicator *) method is missing

The error in the user code is not a bug: the InitIndicators(CIndicator *) method is missing

The letter s is missing, but the compiler message is erroneous, so the SD has taken to fixing it.

fxsaber:

The SDs have taken up the task of fixing it.

You can't fix something that doesn't contain an error. Look in the file <Indicator.mqh> - there will be class CIndicator without letter s

Write to the SR about it. They claim (not me) that there is an error and it will be corrected.

You originally stated the bug - can you explain what it is? What is wrong with it? Here is the simplified code:

class A1 {}; //Indicators
class A2 {}; //Indicator
class BB {
public:
    void f( A1 * ) {}
};
class B : public BB {
public:
    void f( A1 * ) {}
};
void OnStart()
{
    A2* a;
    B b;   
    b.f( a ); //error: 'f' - no one of the overloads can be applied to the function call
}

The compiler's errormessage is not quite correct.

The compiler treats virtual method override as an overload, we will fix it.

Is this the correct compiler message?

int Tmp = 2;
  
if (Tmp % 2) // expression not boolean

[fxsaber]

Is it a bug?

// Добавление элемента в конец произвольного массива
template <typename T>
void AddArrayElement( T &Array[], T Value, const int Reserve = 0 )
{
  const int Size = ArraySize(Array);
  
  ArrayResize(Array, Size + 1, Reserve);
  
  Array[Size] = Value;
}

class A {};
class B : public A {};

void OnStart()
{
  A* Array[];
  
  A* a = new B; // no problem
  AddArrayElement(Array, (A*)(new B)); // no problem
  
  AddArrayElement(Array, new B); // template parameter ambiguous, could be 'A*' or 'B*'
}

[fxsaber]

How do I know the name of a file from its handle?

[fxsaber]

Limitation of language or syntax?

struct A
{
  int i;
};

struct B
{
  const A a;
  
  B() : a({0}) // 'a' - constructor not defined
  {
    const A b = {0}; // no problem
  }  
};
