show alle the pairs of a hash <map>

[THEARTOFWEB]

Hi,

I have an associative array made up like the following:

map<string, string> hash;

I'd like to use a for() to show all the pairs...how can I do that?

thanks

map<string, string>::iterator iter;
for(iter = map.begin();iter!=map.end();++iter)
print(iter->first,iter->second);


where print is your own printing function.

For all STL all containers, there are iterators (or constant iterators) defined that you can access like this (m is a variable of type map<string, string>):

for(std::map<string, string>::iterator it = m.begin(); it!=m.end(); ++it)
{
}

for(std::map<string, string>::const_iterator it = m.begin(); it!=m.end(); ++it)
{
}
