#include<iostream>
#include<ctime>// The function uses the current system time to generate random numbers , Prevent random numbers from being the same
using namespace std;

int main(void)
{
    srand((unsigned int)time(NULL));
    int num = rand() % 100 + 1;
    cout << " Please enter 0 - 100 The random number guessed by :";
    int num2;// The user enters the created variable
    int num3 = 0;
    while (1)
    {
        cin >> num2;
        if (num2 > num)
        {
            cout << " Small handkerchief , The guessed number is greater than the random number ：";
            num3++;
        }
        else if (num2 < num)
        {
            cout << " Small handkerchief , The guessed number is less than the random number ：";
            num3++;
        }
        else
        {
            cout << " It was used "<< num3 <<" Second guess right , Small handkerchief , No way ！";
            break;//break Used to skip the loop
