the fuction is mean,what's read his for binary 's principle

tm -= tm % 44;

1.int GetPrices(int &m, int &a, int &b) This is a fucion of get price,buy i can't understand the "&" is mean,why add the symb 2. int start = FileOpenHistory(Symbol() + Period() + ".hst", FILE_BIN|FILE_READ ); int

i define a array[10], but if iwant use the arraay[10],i must use for(i=0;i<10 i++) array[i]= 0 initial,mt4 have auto initial 's fuction

//+------------------------------------------------------------------+

i can't understand WindowExpertName()'s mean,please help me

int fuction(string a) { int b; for (int i = StringLen(a) - 1; i >= 0; i--) { b = StringGetChar(a, i); if ((b > '`' && b < '{') || (b > '? && b < 256)) a = StringSetChar(a, 1, b - 32); else if (b > -33 && b
