need some questions answered which i cannot get

[halleyc]

Good day
I am trying answer some questions but despite long hours of researching i cannot find them so i am hoping someone here can help me.

I have to find the maximum parameters in each of these 4 functions.

getline
substr
find
erase

If anyone could help me it would be great

There's a good language reference on this site - assuming you're looking for string functions, these are the pages.

http://www.cplusplus.com/reference/string/string/getline/
http://www.cplusplus.com/reference/string/string/substr/
http://www.cplusplus.com/reference/string/string/find/
http://www.cplusplus.com/reference/string/string/erase/

@ wildblue I did look at those pages but none of the number of parameters given are the same as the answers i have to choose from. Thats why i was wondering if i had missed something

[mikeal200]

is one of the answers to choose from for getline 2 or 3 give us the answers you have to choose from please

[halleyc]

for all of them the answers to choose from are the same (given below)

1. 0
2. 1
3. 2
4. 3

What number of parameters are you seeing for getline, just to take the first one, in what you've looked up?

The question is a bit underspecified.

The interface changes with time, and the full names of the APIs are not given.
There are at most 3 arguments to std::getline().
There are at most 2 arguments to whatever std::xxx::substr for whatever valid xxx as of now. There is no std::substr().
There are at most 3 arguments to std::find(), until C++17 when std::find() gains a fourth argument.
There are at most 2 arguments to std::xxx::erase() for whatever valid xxx as of now. There is no std::erase().

The answers may be different pre-C++11: I didn't check.
