C程序骰子游戏

Question

rollDice（ ）应使用兰德（ ）随机生成介于1-6之间的数字

返回兰德（ ）生成的数字

3）实现一个功能，功能原型为Int ；Playgame（ Void ；）； 

根据用户的赢或输的次数给用户一个适当的消息

返回值为EXIT_SUCCESS

这里是我现在拥有的，但它告诉我有错误。有谁能帮我完成这个任务吗？

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

#define WON 0
#define LOSE 1

int rollDice(void);
int playGame(void);

int rollDice(void) {
    return ((rand() % 6) + 1);
}

int playGame(void){
  int dice_1 = 0;
  int dice_2 = 0;
  int sum = 0;
  time_t t;
  srand(time(&t));
  printf("ROLL THE DICE WITH [ENTER]\n");
  dice_1 = rollDice();
  dice_2 = rollDice();
  sum = dice_1 + dice_2;
  if (sum == 7 || sum == 11){
   printf("Congratulations you roll %d and WON at your first try!", sum);
  }
  else {
    printf("Your roll was %d ,you lose try agian.\n", sum);
  }
  return 0;
}

int main (void){
  playGame();
}

X.C:10:1:错误：程序中杂散“\240”

X.C:12:1:错误：程序中杂散“\302”

X.C:16:1:错误：程序中杂散'\240'

Answer 1

这里有几件事不对。

1. 您没有读取/使用playgame()中的返回值。您应该存储结果并对其执行操作。
2. 您的逻辑不完整，因为“为点而打”和输的标准是一样的。
3. 您没有强制程序等待用户按Enter的任何内容。

我在下面为您包含了一个完整的代码列表。

ROLL THE DICE WITH [ENTER]

D1: 3 - D2: 5 - Sum: 8
Playing for point:8. Please hit enter.

D1: 3 - D2: 1 - Sum: 4
Please roll the dice again with [ENTER].

D1: 3 - D2: 2 - Sum: 5
Please roll the dice again with [ENTER].

D1: 1 - D2: 5 - Sum: 6
Please roll the dice again with [ENTER].

D1: 3 - D2: 2 - Sum: 5
Please roll the dice again with [ENTER].

D1: 2 - D2: 6 - Sum: 8
You won the game.
