我正在尝试练习我的 C++，以便在类里面更好地理解，因为我是初学者，有点落后，我遇到了一个有人在网上发布的僵尸游戏。
无论如何，我理解大部分代码，但是我不理解“if(rand() & 67 < 10)”。
我可以解释“rand() % 10 + 1”，其中代码将生成一个数字，在本例中为僵尸，介于 1 和 10 之间。
考虑到玩家选择了一个高数字，起初我认为僵尸的上限为 67，但我不相信这是它的功能，但同样，我不完全确定......
这是我正在查看的代码示例:
我确信它很简单，但我仍然对其目的感到困惑。即使在尝试了解它的功能后我也运行了游戏
为了以防万一，这里是完整的代码:
#include <iostream>
#include <stdlib.h>
#include <unistd.h>
#include <time.h>
using namespace std;
int createZombie() { // createZombie function OPEN
if(rand() % 67 < 10)
return 11;
else
return rand() % 10 + 1;
} // createZombie fuction CLOSED
// #################### MAIN FUNCTION ############################
int main() { // main function OPEN
srand(time(NULL));
char enter;
// game stats
int playerAlive = true;
int playerSkill = 9;
int playerScore = 1;
string playerName = "";
int zombieCount = 0;
int zombiesKILLed = 0;
// title
cout << "Welcome to Zombie War." << endl << "Press [ENTER] to start ";
cin.get();
// player name
cout << "Please enter your name: ";
cin >> playerName;
// ask how many zombies
cout << "How many zombies do you wish to fight? ";
cin >> zombieCount;
cout <<"Get ready to fight for you life, " << playerName << "!" << endl;
// main game loop
while(playerAlive && zombiesKILLed < zombieCount) { // while loop OPEN
// create a random zombie
int zombieSkill = createZombie();
// battle sequence
if(zombieSkill > 10) { // if statment OPEN
cout << endl << "Here comes a huge zombie! " << endl;
} // if statement CLOSED
else { // else statement OPEN
cout << endl << "Here comes Zombie " << zombiesKILLed + 1 << endl;
} // else statement CLOSED
cout << "Fighting... " << endl;
sleep(2);
// zombies killed the player
if(playerSkill < zombieSkill) { // if statement OPEN
playerAlive = false;
cout << "You have died." << endl;
} // if statement CLOSED
else { // else statment OPEN
// PLAYER KILLED THE ZOMBIE
if(playerSkill - zombieSkill > 7) { // if statement OPEN
cout << "You wasted the Zombie! " << endl;
playerScore = playerScore * 2;
} // if statment CLOSED
else if (playerSkill - zombieSkill > 5) { // else if statement OPEN
cout << "You decapitated the Zombie!" << endl;
playerScore = playerScore * 2;
} // else if statement CLOSED
else if (playerSkill - zombieSkill > 0) { // else
if statement OPEN
cout << "You Killed the Zombie!" << endl;
playerScore = playerScore * 2;
} // else if statment CLOSED
else { // else statment OPEN
cout << "You killed the zombie, but suffered injuries." << endl;
} // else statment CLOSED
zombiesKILLed++;
} // else statment CLOSE
cout << endl;
sleep(1);
} // while loop CLOSED
if(zombiesKILLed == zombieCount) { // if statement OPEN
// victory
cout <<"Your have survived the onslaught!" << endl;
} // if statement CLOSED
else { // else statement OPEN
// LOST
cout << "You did not survive the zombie war" << endl;
} // else statement CLOSED
cout << "Zombies killed: " << zombiesKILLed << endl;
cout << "Final score: " << playerScore << endl << endl;
} // main function CLOSED
最佳答案
将命令分成两部分以便于理解:
第一部分-
rand() % 67
= generate any random number from 0-66
= remainder of division of any number by 67
= N (say)
第二部分
if( rand() % 67 < 10)
= if( N < 10)
