计数换行符.




您可能会:

Counting newlines.




You might:

1. 用0初始化lineno.
2. 读取一行，递增lineno.
3. 如果在行内找到该字符串，则退出(lineno包含正确的字符串行号)，否则转到第2点.

1. Initialize lineno with 0.
2. Read a line, increment lineno.
3. If you find the string inside the line the exit (lineno contains the correct string line number) else go to point 2.

请注意，您还应该处理在找到字符串之前结束文件"的情况.

Note you should also handle the ''end-of-file before the string is found'' condition.
