default initialization for built in data types

Question

Hi,

I have studied that each built-in data type supports a special constructor syntax to initialize its object to zero.

XML

For example:
// sets ival to 0, dval to 0.0
int ival = int();
double dval = double();
In the following definition,
// int() applied to each of the 10 elements
vector< int > ivec( 10 );

But when I tried this on my

MSIL

Microsoft Visual Studio 2008
Version 9.0.21022.8 RTM
Microsoft .NET Framework
Version 3.5
Installed Edition: Professional
Microsoft Visual C++ 2008

compiler,I am getting a linker error which states the following:
Error 1 error LNK2019: unresolved external symbol "int__cdecl MyNumber(void)" (?abc@@YANXZ) referenced in function _main

Please help me out,
Thanks in advance.

This error means that you have a function that you used that is not defined anywhere. See if you're missing the function definition for MyNumber().

Solution 2

Hi,
I got the solution,changed the code from

int MyNumber();cout << MyNumber;

to

int MyNumber=int();cout << MyNumber;

Now I am able to get the MyNumber initialized to 0.Thank you both for your replies.

Well thats not at all the code you've provided in your question.
If you would have, it would have been pretty clear what went wrong from the beginning.

Yes,I would keep that in mind!

int MyNumber() doesn't make sense, the error you received was because the compiler/linker assumed that MyNumber() was a function (as did I).
