How ca I return a value from a function
- by Shadi Al Mahallawy
I used a function to calculate information about certain instructions I intialized in a map,like this
void get_objectcode(char*&token1,const int &y)
{
map<string,int> operations;
operations["ADD"] = 18;
operations["AND"] = 40;
operations["COMP"] = 28;
operations["DIV"] = 24;
operations["J"] = 0X3c;
operations["JEQ"] =30;
operations["JGT"] =34;
operations["JLT"] =38;
operations["JSUB"] =48;
operations["LDA"] =00;
operations["LDCH"] =50;
operations["LDL"] =55;
operations["LDX"] =04;
operations["MUL"] =20;
operations["OR"] =44;
operations["RD"] =0xd8;
operations["RSUB"] =0x4c;
operations["STA"] =0x0c;
operations["STCH"] =54;
operations["STL"] =14;
operations["STSW"] =0xe8;
operations["STX"] =10;
operations["SUB"] =0x1c;
operations["TD"] =0xe0;
operations["TIX"] =0x2c;
operations["WD"] =0xdc;
if ((operations.find("ADD")->first==token1)||(operations.find("AND")->first==token1)||(operations.find("COMP")->first==token1)
||(operations.find("DIV")->first==token1)||(operations.find("J")->first==token1)||(operations.find("JEQ")->first==token1)
||(operations.find("JGT")->first==token1)||(operations.find("JLT")->first==token1)||(operations.find("JSUB")->first==token1)
||(operations.find("LDA")->first==token1)||(operations.find("LDCH")->first==token1)||(operations.find("LDL")->first==token1)
||(operations.find("LDX")->first==token1)||(operations.find("MUL")->first==token1)||(operations.find("OR")->first==token1)
||(operations.find("RD")->first==token1)||(operations.find("RSUB")->first==token1)||(operations.find("STA")->first==token1)||(operations.find("STCH")->first==token1)||(operations.find("STCH")->first==token1)||(operations.find("STL")->first==token1)
||(operations.find("STSW")->first==token1)||(operations.find("STX")->first==token1)||(operations.find("SUB")->first==token1)
||(operations.find("TD")->first==token1)||(operations.find("TIX")->first==token1)||(operations.find("WD")->first==token1))
{
int y=operations.find(token1)->second;
//cout<<hex<<y<<endl;
}
return ;
}
which if I cout y in the function gives me an answer just fine which is what i need
but there is a problem tring to return the value from the function so that I could use it outside the function , it gives a whole different answer, what is the problem
