C编程-从文本文件读取同一行中的2个不同目录

Question

I am trying to read two different file directories from a single line in a text file.

eg// under a given.txt file, there are multiple lines of input directory and output directory with a "space" between them in one line

../input1.txt ../output1.txt

../input2.txt ../output2.txt

../input3.txt ../output3.txt

..... etc. so my goal would be loop reading line by line, fetch input#.txt, manipulate it, then send to output#.txt.

My question is, how to separately read directories in each line with a space between them?

I have tried to google the topic, but all of them are either regarding command prompt argc & argv or reading line by line with one directory in each line. eg// under a given.txt

../input.txt

../output.txt

but these aren't what I am searching for

Thanks for your help.

Answer 1

假设路径中不包含空格，则可以在字符串上拆分字符串（使用字符串操作库），这将返回两个标记：第一个是读取路径，第二个是写入路径。

您可以尝试将fscanf()函数与以下格式的字符串"%s %s" 。
