Selection sort problem

sorry to keep harassing you guys but this is hopefully my last question... until next week.

Please take a look at my code (where it says "LOOKY HERE!!!!") and tell me why I am getting this error, thanks:

Code:

error C2664: 'binarySearch' : cannot convert parameter 3 from 'char [30][30]' to 'char []'

>int binarySearch(string name[],int numel, string key);


The third parameter in above function declaration is of type string ( char[30])


>string social[30],phone[30],name[30],key[30];


In above statement you have declared 'key' parameter as array of string type

Now when you call

>x=binarySearch(name,numel,key);


Your third parameter is array of string while in declaration you have mentioned it as only string parameter ( not as array of string)

That is the problem !!!!!!!!!!
