1. implement a function of String randomAlphabetic(int count)

Creats a random string whose length is the number of characters specified;

#include <iostream>
#include <string>
#include <time.h>
using namespace std;

string randomAlphabetic(int count)
{
	string str;
	srand((unsigned int)time(NULL));
	int random;
	char randomChar;

	while (count--)
	{
		random = rand() % 26;
		if (rand() % 2 == 0)
		{
			randomChar = 'a' + random;
		}
		else
		{
			randomChar = 'A' + random;
		}

		str += randomChar;
	}

	return str;
}

int main()
{
	int count;
	while (cin>>count)

		string str = randomAlphabetic(count);
		cout<<str<<endl;
	}
