Re: [algogeeks] I am new to CPP STL please help
strcmp is for C-style strings. Use in-built compare function of C++ strings
( http://www.cplusplus.com/reference/string/string/compare/ ), or why not
simply '==' operator.

In this i have deleted key abc first from hash table name_age in the
next hash table index_namei have abc as value i want to erase the abc
entry from index_name table too,
The idea is to first iterate on hash_map index_name when found abc
delete the entry from index_name but how to compare abc in index_name map.
as we cant do if (strcmp((*it).second, abc) ==0 ) in this , how do i do
the comparision please help

Re: [algogeeks] I am new to CPP STL please help
Iterate through index_name, for each value you traverse, now try to find
inside name_age by calling find on it. Now if it is found, put it temporary
map.
Now the iteration is over, clear index_name map. Put all the values from
temporary map into _name map.

Re: [algogeeks] i am new
This is a great group. Here, we share our knowledge and get to know a lot of new algorithmic techniques.
