蓝桥杯：基础练习杨辉三角形【JAVA算法实现】题目描述杨辉三角形又称Pascal三角形，它的第i+1行是(a+b)i的展开式的系数。它的一个重要性质是：三角形中的每个数字等于它两肩上的数字相加。下面给出了杨辉三角形的前4行： 1 1 1 1 2 1 1 3 3 1 给出n，输出它的前n行。输入格式输入包含一个数n。输出格式输出杨辉三角形的前n 阅读详情

蓝桥杯基础练习杨辉三角形 java Basic6 基础练习杨辉三角形题目如下: 这道题其实是很经典的，身为基础题，讲道理是很好做的，但今天不知道为啥，磨叽了很久才写好这道题的解法是这样的，这里运用了双数组来解决，array1就代表着当前那层的数，而array2就是通过当前层得到的下一层的数，因为数据也是一层层输出的，所以这样写比较好。所以算法的核心就是两层循环，第一次循环代表着层数，就是从第一层到第n层，第二层循环就是输出当前层的数以及得到下一层数的一个过程。坑点有两个，第一个就是array.length可不是你填的数的个数，而是阅读详情

或者重载那两个函数自己写！
参考：
void CMyPlayerDlg::OnButtonOpen()
{
// TODO: Add your control notification handler code here
CString strFilter = "Mp3 File(*.mp3)|*.mp3|";
strFilter += "MPEG File(*.mpg;*.mpeg)|*.mpg;*.mpeg|";
strFilter += "Wave File(*.wav)|*.wav|";
strFilter += "AVI File(*.avi)|*.avi|";
strFilter += "All File(*.*)|*.*|";
CFileDialog dlgOpen(TRUE,NULL,NULL,OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_ALLOWMULTISELECT,strFilter,this);
DWORD MAXFILE = 2412; // allocate enough memory space
dlgOpen.m_ofn.nMaxFile = MAXFILE; // set the buffer size
CString strFileName;
char* buf = new char[MAXFILE];
dlgOpen.m_ofn.lpstrFile = buf;
dlgOpen.m_ofn.lpstrFile[0] = NULL;
if(IDOK == dlgOpen.DoModal())
{
POSITION pos = dlgOpen.GetStartPosition();
while (pos != NULL)
{
strFileName = dlgOpen.GetNextPathName(pos);
// get the individual file name
m_SourceFileList.InsertString(m_SourceFileList.GetCount(),strFileName);// add to Mp3 ListBox
}
}
delete [] buf;
}

CDocTemplate::GetDocString
virtual BOOL GetDocString( CString& rString, enum DocStringIndex index ) const;

Return Value

Nonzero if the specified substring was found; otherwise 0.

Parameters

rString

A reference to a CString object that will contain the string when the function returns.

index

An index of the substring being retrieved from the string that describes the document type. This parameter can have one of the following values:

CDocTemplate::windowTitle Name that appears in the application window’s title bar (for example, “Microsoft Excel”). Present only in the document template for SDI applications.

CDocTemplate::docName Root for the default document name (for example, “Sheet”). This root, plus a number, is used for the default name of a new document of this type whenever the user chooses the New command from the File menu (for example, “Sheet1” or “Sheet2”). If not specified, “Untitled” is used as the default.

CDocTemplate::fileNewName Name of this document type. If the application supports more than one type of document, this string is displayed in the File New dialog box (for example, “Worksheet”). If not specified, the document type is inaccessible using the File New command.

CDocTemplate::filterName Description of the document type and a wildcard filter matching documents of this type. This string is displayed in the List Files Of Type drop-down list in the File Open dialog box (for example, “Worksheets (*.xls)”). If not specified, the document type is inaccessible using the File Open command.

CDocTemplate::filterExt Extension for documents of this type (for example, “.xls”). If not specified, the document type is inaccessible using the File Open command.

CDocTemplate::regFileTypeId Identifier for the document type to be stored in the registration database maintained by Windows. This string is for internal use only (for example, “ExcelWorksheet”). If not specified, the document type cannot be registered with the Windows File Manager.

CDocTemplate::regFileTypeName Name of the document type to be stored in the registration database. This string may be displayed in dialog boxes of applications that access the registration database (for example, “Microsoft Excel Worksheet”).

* sOPath = dlg.GetPathName();//full file path
