Syntax Problem

Syntax Problem

[Joe Hayes]

I have a header file defined as follows: 

//commodity.h
#include <string>

#ifndef COMMODITY_H
#define COMMODITY_H
class Commodity
{
  long commId;
  string description;
  string manufacturerId;

public:
  Commodity(void);
  Commodity(long cId, string descrip, string mfgId);
  void setCommodityId(long cId);
  void setDescription(string descrip);
  void setManufacturerId(string mfgId);
  long getCommodityId(void);
  string getDescription(void);
  string getManufacturerId(void);
};
#endif

And I have another file that makes use of this header file:

//driver.cpp
#include "commodity.h"
int main()
{
 return 0;
}

But when I try to compile, I receive the error:

syntax error : missing ';' before identifier 'description

Along with many other errors. I have tried everything I can think of, and I
still cannot find the error...any suggestions?


Thanks for your help,
Joe

string lives in namespace std.

Try a replace all of "string" with "std::string"

Or simply use "using namespace std;".

Issue group

[ranjith kumar]

Hi
   1)What is an "issues group" ?

  I think its definition is :
             " Processors contain more than one
execution units like integer execution unit, floating
exection unit, memory read/write execution
units.....etc.
An issue group is a list of assembly instructions
which can be issued simultaneously to different
execution units at same time so that all execution
units are busy."


Am I right???

2) Compilers can make use of it by reodering
instructions so that all execution units are busy.
Is GCC exploiting such feature????

Thanks in advane.

More or less.  An issue group is a group of instructions which can all
be issued at the same time.  It is not a requirement that *all*
execution units be busy.

In general, this is target dependent: it requires somebody to write
the scheduler description in the MD file.  It has been done for most
targets, though, including all popular targets.
