我制作的基于文本的僵尸游戏。 （HELP！）

Question

#include <iostream> 
#include <cstdlib> 
#include <ctime> 
#include <string> 

using namespace std; 

void divider(); 

int main()

    int cstats, choice;

    do{cin >> cstats; }

    } 
    srand((unsigned)time(0)); 
    rhp = rand()%50 + 60; 
    hp = rand()%20 + 80; 
    while(hp >0 || rhp > 0)

    cout << "What do you want to do? [1] Normal Attack [2] Magic Attack [3] Defend [4] Dodge\n"; 
    do{cin >> choice; }

    mdmg = (atk - magi) - (mdef/atk); 
    if(mdmg = 0) 
    {

    } 
    rhp = rhp - mdmg; 
    cout << "You did " << mdmg << "damage to the zombie!\n";

    if(rhp <1) 
    { 
     cout << "You killed the Zombie! Congratulations, You won with " << hp << "hp left.\n"; 
     cin.get(); 
     system("pause>0"); 
     return 0; 
    } 
    cout << "The Zombie now has " << rhp << "hp left.\n"; 
    dmg = (matk - agi) - (def/matk); 
    if(dmg < 0) 
    { 
     dmg = 0; 
    } 
    hp = hp - dmg; 
    cout << "The Zombie hit you for " << dmg << " damage.\n"; 
    if(hp < 1) 
    { 
     cout << "You dided. The Zombie still has " << rhp << "hp left.\n"; 
     cin.get(); 
     system("pause>0"); 
     return 0; 
    } 
    cout << "You now have " << hp << " hp left.\n"; 
} 
} 
} 
void divider() 
{ 
    cout << "*************************************\n"; 
} 

所以，是的。这是我制作的游戏。所有的东西都在工作，但是损坏的东西没有工作。我不知道我是否犯了错误。我在这里找不到什么错。我的眼睛现在准备好睡觉了。 O.O我现在连续3天没有体面的睡眠。提前致谢！

if(mdmg = 0)应该是布尔if(mdmg == 0)。您将其分配为0而不检查它是否为0。
