举一反三
- 打开一个已经存在的非空文本文件，若文件名为stu，则正确的打开语句为() A: FILE*fp； B: fp＝fopen("stu．txt"，"r") C: B．FILE*fp； D: fp＝fopen(stu．txt，r) E: C．FILE*fp； F: fP＝fopen("stu，txt"，"wb") G: D．FILE*fp； H: fp＝fopen("stu．txt"，w
- 若有定义FILE *fp，则下列哪条语句可以实现将以写的方式打开文件d:\\stu.txt文件( ) A: fopen_s(&fp,“d:\\stu.txt”,"w") B: fopen_s(&fp,“d:\\stu.txt”,"w"); C: fopen_s(&fp,“d:\\stu.txt”,"r"); D: fopen_s(&fp,“d:\\stu.txt”,"wb");
- 下列程序的功能是：将数据1,2,..,8写入顺序文件Num. txt中请补充完整。 Private Sub Form_Click ( ) Dim i As Integer Open "Num. txt" For Output As #1 For i = 1 To 8 【13】 Next Close #1 End Sub
- 用（ ）语句打开顺序文件File1.txt后，可以进行写操作 A: Open "File1.txt" For Input As B: 1 C: Open "File1.txt" For Output As D: 1 E: Open "File1.txt" For Random As F: 1 G: Open "File1.txt" For Binary As H: 1
- 要从磁盘上读入一个文件名为"d:\File.txt"的顺序文件,下面程序段正确的是( ). A: Open d:\File.txt For Input As B: 1 C: Open "d:\File.txt" For Output As D: 2 E: Open "d:\File.txt" For Input As F: 2 G: Open "d:\File.txt" For Append As H: 1
