It will associate a new type alias for the given structure, and we’d need to specify only the new alias name in the function prototype. Now, functions in C can return thestructsimilar to the built-in data types. In the following example code, we implemented aclearMyStructfunction that ...
Syntax of a function declaration returning structure Following is the syntax of a function declaration that will return structure. returnType functionName(dataType paramName, ...); Example: struct student getDetail(void); In the above example we have a function by the namegetDetail. The parameter...

一. 结构(Structure) 什么是结构(Structure)?在C#里,Struct是一种值类型,通常用来封装小型相关变量组,和类有很大的相似度.同类一样,它不但可以包含不同数据类型数据。还可以包含复合类型(数组,结构,DateTime等等)除了以名字/值方式出现还可以有属性和方法,所以说结构是一种强大的复合型数据。
请注意,在bPrintSetupOnly设置为FALSE的情况下调用构造函数时,会自动使用PD_RETURNDC标志。 调用DoModal、GetDefaults或GetPrinterDC后,将在m_pd.hDC中返回打印机 DC。 必须由CPrintDialog的调用方通过DeleteDC调用来释放此 DC。 示例 C++ // Display the Windows Print dialog box with "All" radio button// initi...
