Can I initial a static global variable by calling a function in C language? -


Can I start a stable global variable by calling a function in C language? For example: 

  Fixed int var_01 = funny ();

When I use it in VC6, it succeeds. But it failed in GCC 4.6.1. it's so weird. I think this experiment is illegal in C89? Or is the reason for this reason?

In C99 and as far as I know in C89 draft C99 standard section 6.7 .8 Start :

An object with a static storage period from the draft must be either a continuous expression or string literal.

All expressions in the initialization for the constant frequency object will be constant expressions or string literals.

>

When they are contained within a subexpression that has not been evaluated. 9 8)

Both GCC generates the same error using -std = c99 and -std = C89 , notice that I am using the following flag -Wall -Wextra -pedantic .

This version of the Visual Studio compiler does not work in C ( ) in modern versions, but it works in C ++. That's why you may be compiling it in Visual Studio as C ++.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
