Question: How do I find my posts in MQL4 forum? About two years ago a thread was created with attached code and this code has now become interesting, but forum search is silent. If I go into my publications, this topic is not there. (deleted?)

As far as searches go, the best helper here is... Google.

Use the built-in search on mql4.com by entering your login in the author field

It's probably not me who needs to answer, but the person who asked the question. I understand that he tried to do it and failed.

I have a different question now. Is there another indexing engine at mql4.com, different from local one? Is it better?

[Renat Fatkhullin]

The engine is the same one that searches its data

It is not possible to specify a default parameter value in the function template:

template<typename T>
void Func1(T t1, T t2 = 0)     // error: '0' - illegal operation use
{
}

template<typename T>
void Func2(T t1, T t2 = T())   // error: 'T' - function not defined
{
}

Cannot specify default parameter type:

template<typename T = int>   // '=' - syntax error
void Func3(T t)
{
}

A What result do you expect?

template<typename T>
string Func1(T t = NULL) { return typename( T ); }
void OnStart()
{
        Print(Func1(   )); //какой ожидается результат?
        Print(Func1( 1 )); //нормально
}

A100:
And what result do you expect?

As in sys - initialization by default type constructor:

#include <iostream>
using namespace std;

template<typename T>
void Func(T t1, T t2 = T())
{
        cout << "t1 value: " << t1 << endl;
        cout << "t2 value: " << t2 << endl;
}

int main()
{
        Func(1);      // t1 value: 1    t2 value: 0
}

And in MKL it doesn't compile:

template<typename T>
void Func(T t1, T t2 = T())    // 'T' - function not defined
{
        Print("t1 value: ", t1);
        Print("t2 value: ", t2);
}

void OnStart()
{
        Func(1);

}

PS. In the previous example I threw too much out of the code and left only one parameter in the functions, this was really wrong. Corrected.

Thank you, it will be fixed.
