您如何忽略输入行的其余部分并从下一条输入行开始恢复？

Question

I just started learning C. How do you ignore the rest of an input line and resume on the next input line? For example:

Input:

123456789123456789
hello how are you 

Output:

123456
hello h

Answer 1

Short answer is you can't. When working with input, especially command line and or program input. You have to process it, argument by argument, line by line.

I would suggest that you use delimiters ("$","\\n","&") to better manage your input.

Answer 2

I'm really not sure what's your question, but do you mean something like this?

scanf("%6s%*[^\n]", string);
scanf("%*c%6s", string + 6);
