Help with "identifier not found" error.

[zeebo17]

Hi,

I have a function get_array_data in a visual C++ code which is defined here:

int CCleanViewDlg::get_array_data (float range_input, float sobp_input, float total, float delivered, int spread);
 

and defined in the header file here:

int get_array_data(float range, float sobp, float total, float delivered, int spread);
 

and called here:

int m_depth_bin = get_array_data(range, sobp, total_mu, delivered_mu, spread);
 

and is giving the error " 'get_array_data': identifier not found" but I can't figure out why. Is there any other part of the code that might be relevant? Any suggestions would be greatly appreciated!

Thanks!

Both of your first two code snippets look like function declarations (that is, function prototypes). The function definition has the body of the function enclosed in braces. Where is your function definition? Notice that the function definition never has a semicolon after the closing parenthesis while a function declaration always has a semicolon after the closing parenthesis.

This answer is accurate for C. Perhaps C++ does things differently.

Oops sorry I pasted that wrong, the function is defined as

int CCleanViewDlg::get_array_data (float range_input, float sobp_input, float total, float delivered, int spread){
...BLAH.... ;
}

Your function definition is prefaced by CCleanViewDlg:: but the declaration and invocation aren't. Might that be part of your problem?

Disclaimer: I'm an unrepentant C programmer. I'm only guessing at this C++ folderol.

By the way, is the header with the function declaration included by the source file with the function invocation?

If your function is CCleanViewDlg::get_array_data, then you need a CCleanViewDlg object in order to call the function. You can't just call it by itself as in C.

Using a scope resolution operator (::) is how C++ lets you have multiple functions with the same name. You can have many get_array_data function as long as each one has a different named scope.
