我有一个两人猜随机数游戏；游戏开始时随机生成玩家编号（1 0r 2），并提示输入玩家编号。如果输入的玩家编号与随机玩家编号不匹配，则应打印“您必须等待轮到您”并返回输入玩家编号提示。我的程序直接进入玩家要猜测的随机数，而不是先询问玩家号码，然后再要求输入轮到玩家猜测的随机数。在继续之前，我如何让它回到询问正确的玩家号码。

还输入了一个正确的玩家号码；每个玩家可以选择通过连续两次输入“PASS”，并在整个游戏生命周期中三次输入“PASS”。我如何使这些条件在游戏中发挥作用。在此先感谢大家。

这是代码：

#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <malloc.h>

int main(void) { 

    int player_num = 0; int number = 0; int player_input = 0;
    int guess = 0; char input; char str[6] = {0}; int Player_1 = 1;
    int Player_2 = 2; int Pass_1 = 3; int Pass_2 = 3; int i = 1;
    int player_turn = 0; int turn = 0;

    srand(time(NULL));  player_num = 1 + rand() % 2; /* Random number is generated */
    srand(time(NULL));  number = 0 + rand() % 100; /* Random number is generated */

    while(number != guess) {

        printf("\nIt's player's %d turn\n", player_num);
        printf("Player Number?\n");
        scanf("%d", &player_input);

        while (player_num != player_input) {
            printf("You Have to wait your turn.\nPlayer number?\n");
        }

        if (Player_1 != player_num)
            Player_2 = player_num;

        if (i%2 == 1) {
            player_num = Player_1;
        } else {
            player_num = Player_2;
        }

        i = i+1;

        printf("Enter Your Guess, 0 - 100 or Pass: ");

        scanf("%s", str);

        if (strcmp(str, "pass") == 0){
            if (player_num == Player_1){
                Pass_2 = Pass_2 -1;
                printf("Player 2 has %d more 'Pass' left!\n", Pass_2);
            }   
            else {
                Pass_1 = Pass_1 -1;
                printf("Player 1 has %d more 'Pass' left!\n", Pass_1);
            }
        } else {
            guess = atoi(str);
            if(guess < number) /* if the guess is lower, output: the guess is too low */
                printf("Your guess was to low.\n ");

            else if(guess > number) /* if the guess is higher, output: the guess is too high */
                printf("Your guess was to high.\n ");

            else /* if the guess is equal to the random number: Success!! */
                printf("Yes!! you got it!\n");

        }
    }
    return 0;
}

首先，srand只需要在程序开始时调用一次。

其次，scanf在第二个 while 循环中移动，以强制用户输入正确的玩家号码或继续询问，直到他/她正确为止。

以下代码修复了上述所有问题。请阅读代码中的注释以查看更改原因：

#include <stdio.h>
#include <time.h>
#include <string.h>
#include <stdlib.h>
#include <malloc.h>

int main(void) { 

 int player_num = 0; int number = 0; int player_input = 0;
 int guess = 0; char input; char str[15] = {0}; // size was increased to compensate for pass pass input
 int Player_1 = 1;
 int Player_2 = 2; int Pass_1 = 3; int Pass_2 = 3; int i = 1;
 int player_turn = 0; int turn = 0; int alternate=0;
 int player1Flag=0,player2Flag=0;

 int lastPlayer=0;

 srand(time(NULL));  
 player_num = 1 + rand() % 2; /* Random number is generated */
 lastPlayer = player_num;
 number = 0 + rand() % 100; /* Random number is generated */

  while(number != guess) {

      while (player_num != player_input)    {
           printf("\nIt's player's %d turn\n", player_num);
           printf("Player Number?\n");
           scanf("%d", &player_input);
           getchar();// to get rid of \n after the input

           if(player_input!=player_num){
               printf("You Have to wait your turn.\n");
           }

      }

      if (Player_1 != player_num) Player_2 = player_num;


      printf("Enter Your Guess, 0 - 100 or Pass: ");

      scanf("%s",str);

     if (strcmp(str, "pass") == 0){
        if (player_num == Player_1){

您需要在 while 内添加一个输入。换句话说，而不是：

   while (player_num != player_input)    {
     printf("You Have to wait your turn.\nPlayer number?\n");
   }

尝试这个：

while (player_num != player_input)    {
   printf("You Have to wait your turn.\nPlayer number?\n");
   scanf("%d", &player_input);
}
