    Strings as integers

    Hi, how would I convert a string such as "ThisisASTRing" to an integer. I'm trying to find the key value for a hash table which has a size around 1055 spaces.

    You can't get the integer value for a string. But you can get the integer value for a character.

    You can use atoi...

    int atoi ( const char * str );

    atoi - C++ Reference

    Or parsing it yourself wouldn't be too hard (though a waste of time IMO). Loop through each character, convert it to numerical value from char encoding (probably ASCII), multiply it by the base and accumulate it.

    I suspect what unknown_ is looking for is "string hashing" or "hash function". Searching for those terms using google will provide plenty of information - albeit, like all such things on the internet, a mix of good and bad.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.
