//This is the code from eclipse,once i copy and paste in visual studio 2013 it's  working,but if i try to enter
 //everything manualy -create class/constructors,i stack on the creatring constractor
 //function line-Animal(const string & n, const string & t, const string & s)
 // and so on,can some one explaine how to manualy enter everything in visual studio 2013.Thank you.

Specify your question a little more. Are you asking how to start and create a c++ file in visual studio or if when you write this code an error appears when debugging it but not when you paste the same code?

[aluhnev]

The question is how to create class and enter that costructors,in visual studio,but not to type everything on one page.the problem is to create costructor with wizard.

[NathanOliver]

Go to Project -> Add Class. That will create a new class and bring up the class wizzard.

[aluhnev]

Thats good ,i now,but i mean how to create that costructor-Animal(const string & n, const string & t, const string & s)I enter class name,than how to finish that line typing in wizzard? Thanks

[NathanOliver]

Honestly I never use the wizzard. I just write the code.
