win7, vc6；新建一个控制台程序；代码如下 ；

#include <afx.h>
    #include <stdio.h>
    
    int main()
    {
    	int			lo, hi;
    	CString		str;
    	CStdioFile	pFile;
    	
        pFile.Open("test1.txt", CFile::modeWrite |
    						   CFile::modeCreate|
    						   CFile::typeText);
    	
        str.Format("%s/n", "Fibonacci sequencee, less than 100 :");
        printf("%s", (LPCTSTR) str);
        pFile.WriteString(str);
    	
        lo = hi = 1;
    	
        str.Format("%d/n", lo);
        printf("%s", (LPCTSTR) str);
        pFile.WriteString(str);
    	
        while (hi < 100)
        {
            str.Format("%d/n", hi);
            printf("%s", (LPCTSTR) str);
            pFile.WriteString(str);
            hi = lo + hi;
            lo = hi - lo;
        }
    	
        pFile.Close();
        return 0;
    }

构建；出错如下；

工程做如下设置；

好了；

创建文件并写入内容；这是用mfc类做的；
