how to split cin input

Question

I am facing problem to split my input in C++, for something similar to the Python split function.
The input is given as 1001-43 1003-45 1008-67 in different lines. I want to know how to take these inputs split by '-' and store them in different variables.

In Python it's:

a, x = input().split('-')

Have a look at boost. The string algorithms library includes most of what you can find in python including a split function which splits a string into an stl container of your choice. For example (lifted from their docs) splitting on dash or asterisk:

std::string str1("hello abc-*-ABC-*-aBc goodbye");

std::vector< std::string > SplitVec; // #2: Search for tokens
split( SplitVec, str1, is_any_of("-*"), token_compress_on );

// SplitVec == { "hello abc","ABC","aBc goodbye" }

int number,digit1,digit2,digit3;
std::cin>>number;
digit1=number%10;
digit2=number%100;
digit3=number%1000;

Personally, I think that `strtok` is a very bad recommendation because of its legacy non-reentrant interface. – CB Bailey Jul 01 '12 at 08:58
`strtok` is a good recommendation for C, but not necessarily for idiomatic C++. – Alex Wilson Jul 01 '12 at 09:04

`strtok` is super-super-awful – Puppy Jul 01 '12 at 09:08
