c++ - C ++中数组中的随机字符串

Question

我试图让程序从数组中输出随机攻击，monsterAttack但它一遍又一遍地输出相同的东西，有人可以帮我解决这个问题吗？

我的代码：

/* Skyy Civil
C++ Legend Game
*/
#include <iostream>
#include <cstring>
#include <fstream>
#include <random>
#include <vector>
using namespace std;

/*
Declaring functions
*/
void Menu();
void Login();
void LevelStart();
void GameMenu();

/* No files, struct instead.

structing monsters and hero and damage
*/
struct Monster{
    int monsterCount;
    string monsterType;
    int monsterHealth;
    
};

// Hero
struct Hero{
    int coins;
    int health;
    
};


struct Attacks{
    string attack1;
    string attack2;
    string attack3;
    string attack4;
    int damageAttack1;
    int damageAttack2;
    int damageAttack3;
    int damageAttack4;
};


/*
        The actual level starts here
*/
