带分段的客户端服务器代码错误错误

Question

我正在编写客户端服务器的网络编程项目Rock Paper Scissors代码。我完成了代码，在测试过程中它运行良好，然后将此行添加到代码中。

findWinner(gameType,pcChoice); 

当我将代码行添加到代码时，代码开始给我一个关于来自服务器端的分段错误的错误。这是我添加该行的地方。

while(1) 
{ 
    int gameType; 
    printf("Paper, Scissors, Rock game start.\n"); 

    rc = read(client_sockfd, &gameType, 1);  
srand(time(NULL)); 
pcChoice = (rand() % 3)+1; 
findWinner(gameType,pcChoice); 
    gameType = pcChoice; 
    write(client_sockfd, &gameType, 1); 

} 

我是C中的一个熟人，不知道该怎么做。

int pcChoice; 

它是一个整数，以保持一个随机整数1至3个（岩纸或剪刀）

findwinner（）：

void findWinner(int player,int pc) 
{ 
const char *items[3]={"Paper","Scissors","Rock"}; 
printf("Client: %s\n",items[player-1]); 
printf ("Computer: %s\n",items[pc-1]); 

switch (player) 
{ 
    case 1: 
     switch (pc) 
     { 
      case 1: 
       printf("it is a DRAW\n"); 
       break; 
      case 2: 
       printf("Computer Wins\n"); 
       break; 
      case 3: 
       printf("Computer Loses\n"); 
       break; 
      default: 
       printf("ERROR\n"); 
       exit(0); 
     }; 
     break; 
    case 2: 
     switch (pc) 
     { 
      case 1: 
       printf("Computer Loses\n"); 
       break; 
      case 2: 
       printf("it is a DRAW\n"); 
       break; 
      case 3: 
       printf("Computer Wins\n"); 
       break; 
      default: 
       printf("ERROR\n"); 
       exit(0); 
     }; 
     break; 
    case 3: 
     switch (pc) 
     { 
      case 1: 
       printf("Computer Wins\n"); 
       break; 
      case 2: 
       printf("Computer Loses\n"); 
       break; 
      case 3: 
       printf("it is a draw\n"); 
       break; 
      default: 
       printf("ERROR\n"); 
       exit(0); 
     }; 
     break; 
    default: 
     printf("ERROR\n"); 
     exit(0); 
} 
} 

Answer 1

while(1) 
{ 
    int gameType; 
    printf("Paper, Scissors, Rock game start.\n"); 

    rc = read(client_sockfd, &gameType, sizeof(gameType));  
    srand(time(NULL)); 
    pcChoice = (rand() % 3)+1; 
    findWinner(gameType,pcChoice); 
    gameType = pcChoice; 
    write(client_sockfd, &gameType, sizeof(gameType)); 

} 

其他事情可能是有问题的是：

尝试显式null终止char*

const char *items[3]={"Paper\0","Scissors\0","Rock\0"}; 

你确定玩家从不消极或大于3吗？

printf("Client: %s\n",items[player-1]); 
printf ("Computer: %s\n",items[pc-1]);
