When you say Foo bar; you are declaring the variable `bar' being of type `Foo'
For as long as bar lives, it will be a Foo. It can't be anything else, just Foo.

string dependents = GetInput("Dependent"); //dependents is a string
dependents = atoi(dependents.c_str()); //still a string
Employee1.setDependents(dependents); //still a string 

and you are trying to pass a `string' when your function expected a number.

string dependents = GetInput("Dependent");
Employee1.setDependents( atoi(dependents.c_str()) );

Because doing

std::string s;
s = 'c';

is valid, you didn't receive any complains when assigning the result of atoi()
