Code not recognizing “#include” statements

Question

I'm writing some header files for a project, but for whatever reason, I'm getting the error "Identifier ' ' is undefined. What am I doing wrong? (It won't recognize string or Boolean as correct)

#include <iomanip>
#include <iostream>
#include <string>

class Camper {
private:
    string name;
    boolean paid;
public:
    void setName(string);
    void getName() const;

    void setPaid(boolean);
    void getPaid() const;

    void display() const;
};

Booleans are actually typed as bool in c++ .Also the reason it wont recognize string is that string is part of the std namespace .You either need to add using namespace std; under your includes,or else you need to adress string as std::string .Some more elements from the std namespace are Vector,List,etc.You can take a look at those here

EDIT:Also I just noticed your getter/setter methods.A getter method is used so you can access Object attributes without them being public,it returns a type of that attribute.If you want to access name described as an std::string your method should return std::string .Meaning your 2 getters should look like this:

bool getPaid() const;
std::string getName() const;

As LF pointed out it is not good practice to use namespaces as it can lead to confusing or even conflicting code.The reference is this
