sscanf 你会用吗?
Description
You have just moved from Waterloo to a big city. The people here speak an incomprehensible dialect of a foreign language. Fortunately, you have a dictionary to help you understand them.
Input
Input consists of up to 100,000 dictionary entries, followed by a blank line, followed by a message of up to 100,000 words. Each dictionary entry is a line containing an English word, followed by a space and a foreign language word. No foreign word appears more than once in the dictionary. The message is a sequence of words in the foreign language, one word on each line. Each word in the input is a sequence of at most 10 lowercase letters.
Output
Output is the message translated to English, one word per line. Foreign words not in the dictionary should be translated as "eh".
Sample Input
dog ogday
cat atcay
pig igpay
froot ootfray
loops oopslay
atcay
ittenkay
oopslay
Sample Output
cat
eh
loops
看到这个输入了吗?你有更好的处理方法吗?
说实在的我真的对这个有点蛋庝呀。
然而,自从认识了sscanf以后,心里就爽快多了。
到底如何使用sscanf呢?听我慢慢道来……
就针对第一行了输入dog ogday来说,
我们用gets(c)来存入dog ogday这个字符串,
接下来就该sscanf上场了。
sscanf(c,"%s%s", a, b);
这个时候,我们可以看到a=dog; b=ogday;
对了,被你说中了,sscanf的作用就是拆分。
将c拆分成两个子串。
难道只可以拆成两个个子串吗?
答案是否定的。
要拆成几个就要根据你的输入了。
也就是说可以是三个,四个,五个……
好了,就说到这里吧!
