c++ help in graph

create graph using randomly generated number for adjacent vertices: rand%s

======

struct node {

int vertex;

bool visited;

node *next;

};

class graph {

private:

node **g; //g is an array of vertex

int size;

public:

graph(int s = 10);

bool isEmpty();

void createGraph();

void print();

~graph();

};

graph::graph(int s) {

g = new node[s];

}

int main(int argc, const char * argv[]) {

}
