The following code throws up parse errors, can anyone tell me why?

// Demonstration of variables
#include <iostream>
using namespace std;
#include <stdlib.h>

typedef unsigned short int USHORT;  //typedef defined

int main()
{
    USHORT Width = 5,
    USHORT Length;
    Length = 10;
   
    //create an unsigned short and initialize with result
    //of multiplying width by length
    USHORT Area = Width * Length;
   
    cout << "Width: " << Width << "\n";
    cout << "Length: " << Length << endl;
    cout << "Area: " << Area << endl;
    system("pause");
    return 0;
}

USHORT Width = 5,

You have a , instead of a ;

would test that theory, but don't have Dev re-installed yet

P.S.  Dbl clicking on the error/Warning, should highlight the conflicting line.  It also tells you the line #

Yes, Curtis is right on,  fix the , to a ;, and it works perfectly.

Parse errors, for me at least, ase usually missing ; or unpaired {} or ().

This also points our the importance of looking at first errors first, the ; error tripped multiple errors, fixing the ; fixed them all.  Note my compile log with the error:

Ditto. The error messages contain INFORMATION  -don't be scared, read them! (Although I admit, plain English is often not the compiler's strong point - but the line number will tell you where to start looking).

Or, if ytou double click on the error message, it takes you to the line in question.

Note that missing ; can be tricky, the error might show up much later in the code...

It now works fine. I just could not see that "," i must have been going code blind.

Thanks people.

I *never* do anything like that!
