    Need help with String

    for some reason my compiler doesn't see String data type.
    below is my code
    Code:
    #include<iostream.h>
    #include<string.h>
    
    void main()
    {
    
    
    	string name = " ";
    	string nameMin = " ";
    	string nameMax  = " ";
    
    ....
    ....
    ....
    }
    it tells me that string is undeclared identifier.

    Am I declaring it wrong?

    Thanks

    Try using:
    Code:
    char arrayname[max number of charsinarray];
    To code is divine

    Yes, i tried that.

    But isn't there an actual string data type, i.e. string name="John Doe";
    shouldn't it work? it doesn't even turn blue color like other data type.
    am i missing something?

    See if the following works for you:
    Code:
    #include <iostream>
    using std::string;
    
    int main()
    {
    	string s;
    	return 0;
    }

    It works now

    this is what I did

    Code:
    #include<iostream>
    #include<string>
    
    
    using namespace std;
    
    using std::string;
    
    
    int main()
    {
    
    
    	string name = " ";
    	string nameMin = " ";
    	string nameMax  = " ";

    and it worked

    Thanks everybody

    Just to clarify; std::string isn't a 'real' C++ data type. It's part of a Class. That's why it didn't turn blue, like char or int would.

    That's good that you got it working, though.

    it was probably because you kept the ".h" at the end of the headers... you need the following for the string class:

    Code:
    #include <iostream>
    #include <string>
    
    using std::string;
