推荐答案

好的...首先你需要确定你输入的字符串：因为你必须处理它们不一样。

替代方案是：总是删除逗号并拆分字符串......所以我们会看一下。

但是......这听起来像是你的作业，所以我会让你写代码！

这并不复杂：

1）分配两个字符串，每个字符串足以容纳整个输入。 （所以如果没有什么可以删除，你只需继续复制即可。）

2）通过输入前进，将每个字符复制到第一个输出 - 除非它是逗号，其中案件不要复制它。当你到达字符串的末尾或句号时，停止。

3）通过输入的其余部分（如果有的话）前进，将其复制到第二个输出，直到结束。



完成！

Ok...first you need to decide which string you have as input: because you will have to process them differently.
The alternative is: always remove the commas and split the string...so we will look at that.
But...this sounds like your homework, so I'll let you write the code!
It's not complex:
1) Allocate two strings, each big enough to hold the whole input. (So if there is nothing to remove, you just keep going and copy it all.)
2) Advance through the input, copying each character to the first output - unless it is a comma, in which case don't copy it. When you hit the end of the string, or a period, stop.
3) Advance through the rest of the input (if any), copying it to the second output, untiul you reach the end.

Done!
