StringTrimLeft and StringTrimRight functions mql5

[Andrei Gabriel]

Hello guys,

I have a problem with StringTrimLeft and StringTrimRight, because they are integers in mql5. In mql4 source code, all is good because they are strings there. How I fix them for exactly solution in mql5 like in mql4?

string exp = FileReadString(handle);

exp =  StringTrimLeft(StringTrimRight(exp));

In MQL5 it's passed by reference, use it like so:

string s = FileReadString(handle);
StringTrimLeft(s);
StringTrimRight(s);
