Randomly generates 10 passwords that contain 32-digit digits or characters

As a title, we randomly generate 10 passwords containing 32 digits or characters (numbers and passwords contain at least 1 digits).

The implementation code is as follows:

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

void Generatecode ()
{
	for (int i = 0; I!=. ++i)
	{
		vector<int> State (0);
		Vector<char> Code ("0");
		int sum = 0;
		for (int j = 0; J!= ++j)
		{
			State[j] = rand ()% 2;
			Sum + + state[j];
		}
		if (sum = = | | sum = = 0)
		{
			int r=rand ()% + 1;
			STATE[R] = 1-state[r]; 
		}
		for (int i = 0; I!= ++i)
		{
			if (state[i] = = 0)
				Code[i] = rand ()% + ' 0 ';
			else
				Code[i] = rand ()% + ' a ';
		}
		for (Vector<char>::iterator iter = Code.begin (); Iter!= code.end (); ++iter)
		{
			cout << *iter;
		}
		cout << Endl;
	}
int main ()
{
	generatecode ();
	System ("pause");
	return 0;
}

The experimental results are as follows:
