I am currently trying to implement vectors and stacks on a c++ program with the vector declared in the class. When I have the vector defined as: "vector<string> firstName;" in the class under public, I am getting errors C2143, C4430, and C2334. Due to the vector not being able to be used, I also get C2039 throughout the program I am working on. What do you think is the problem? I have included the code for the class that is causing the problem below and if I need to show more, I can do that: class Customers { public : vector <string> firstName; int balance; private: protected: };

#include <vector> #include <string> using namespace std; Do you have the above in your code?

Why am i getting errors C2143, C4430, and C2334?

#include <vector> #include <string> using namespace std;

Do you have the above in your code?

Yes. I currently have those, #include <iostream> and #include <stack>.

confirm you have string included as well or otherwise this might be the problem

Show us all the includes and more of the code. So far we don't have enough information from you.

Here it is so far. I am trying to use the vector I have defined in the class Customers in place of the vector in main. However, I currently am getting the errors listed above. C2143 and C4430 with the vector declaration in the public of the class, then C2039 with the usage of the vector in the class.

include <iostream>

include <stack>

include <string>

include <vector>

include <cstdlib>

include <ctime>

class Customers {
public :
vector <string> firstName;
int balance;
private:

protected:

};

int main()
{
Customers C{};

vector<string> firstName = { "Sam", "Jonathan", "Jacob", "Jim", "Jacob", "Zack", "Alec", "John", "Smith"}; //C.firstName = { "Sam", "Jonathan", "Jacob", "Jim", "Jacob", "Zack", "Alec", "John", "Smith"}; stack<string> names; int value = 0; int n; cout << "Choose the number of iterations <<< "; cin >> n; for (int j = 1; j <= n; j++) { for (int i = 0; i < firstName.size(); i++) { names.push(firstName.at(i)); if (value % 5 == 0) { cout << "The next customer is " << firstName.at(i) << endl; } value += 1; } j++; } return 0;

}

Your code omits using namespace std;.

Insert the using statement after all of the include statements.

I just noticed that as well. It has given me the same error with "using namespace std;" as well.

Where exactly did you place the using statement?

in between class definitions and main(),

I told you to place the using statement right after the include statments!!!
