I got a couple of errors when I tried to compile it as follows:

Line 47:
cin >> s This created an error " error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
I did #include <string> and that sorted the problem.

Line 56
This created the error error C2360: initialization of 'iter1' is skipped by 'case' label
Enclose the code for the case:6 inside brackets like this to stop this error:

case 6: 
{
	inpout1();
	cout<<"enter the searched item:::"<<endl;
	cin>>s;
	string search_item(s);
	typedef multimap<string,string>::size_type sz_type;
	sz_type entries=ckt.count(s);
	multimap<string,string>::iterator iter1=ckt.find(s);
	for(sz_type cnt=0;cnt != entries;++cnt,++iter1)
	{
		cout<< "the elements are:::::::::"<<iter1->second <<endl;
	}
				
	break;
}
		

Line 51,52,53,54 - I'm not an expert on containers but this loop does not seem right (maybe someone else can help you out here).

If you would post the errors you (srinivas) get, we could better help...
Line 51..54 don't look so bad, although it is always dangerous to mix iterator increments and a loop based on size / counting - you may end up with an iterator incremented beyond the size of the container.
