已存在文件file.txt，其内容为sample1234ASDw，请写出程...

语句QEw DB’AsDF’是合法的。( )

此题为判断题(对，错)。

编写一个函数findStr()，该函数统计一个长度为2的字符串在另一个字符串中出现的次数。例如，假定输入的字符串为"asd asasdfg asd as zx67 asd mklo"，子字符串为“as”，函数返回值是6。

函数ReadWrite()的功能是实现从文件in40.dat中读取两个字符串，并调用函数findstr()，最后把结果输出到文件out40.dat中。

注意：部分源程序已给出。

请勿改动主函数main()和其他函数中的任何内容，仅在函数findStr()的花括号中填入你所编写的若干语句。

M: Yeah. But 50% off what?

W: 2,400 dollars.

M: You spent $ 1,200 on a TV?

W: It's got a lot of special features. Look at this remote control.

M: I'm sure. But that's still a lot of money for a television. I didn't think you watch TV that much.
