define a vector in a class? and put this class in another vector?

[northfly]

First this is my code:

#include <iostream>
#include <vector>
#include <cstdlib>

using namespace std;

class pore_t {
	int T[4];
};

class throat_t {
	int P[2];
};

class cluster_t {
	vector<pore_t> P;
	vector<throat_t> T;
};

int main() {
	vector<cluster_t> C;

	cout<<"Input Cluster Numbers:"<<endl;

	int clusterN;
	cin>>clusterN;
	for(int i=0; i<clusterN; i++) {
		cluster_t currentC;

        srand(i);
		int dimension=rand()%10+1;

		for(int j=0; j<dimension; j++) {
			currentC.P.push_back(j);
			currentC.T.push_back(j);
		}

		C.push_back(currentC);
	}
	cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
	return 0;
}

the blacked content got problems: the error messages are the throat_t::P or throat_t::T is inaccessible. How to fix this? Thanks.

classes default to private members. If you want access to them from outside the class you need to make them public:

class pore_t{
{
public:  // <- need this
    int T[4];
};

// repeat for your other classes 

Also... your P and T vectors are of pores and throats... not of ints. 'j' is an int... so you can't push_back j into those vectors. You need to push_back a pore_t or a throat_t.

You haven't declared your access specifyors to be able to access your T and P class members from outside you need to declare them as public:

class pore_t
{
public:
   int T[4];
};

class throat_t
{
public:
   int P[2];
};

class cluster_t
{
public:
   vector<pore_t> P;
   vector<throat_t> T;
};
