Split string by single spaces [duplicate]

Answer 1

Can you use boost?

samm$ cat split.cc
#include 
#include 

#include 

#include 
#include 
#include 

int
main()
{
    std::string split_me( "hello world  how are   you" );

    typedef std::vector Tokens;
    Tokens tokens;
    boost::split( tokens, split_me, boost::is_any_of(" ") );

    std::cout << tokens.size() << " tokens" << std::endl;
    BOOST_FOREACH( const std::string& i, tokens ) {
        std::cout << "'" << i << "'" << std::endl;
    }
}

sample execution:

samm$ ./a.out
8 tokens
'hello'
'world'
''
'how'
'are'
''
''
'you'
samm$
