帶分段的客戶端服務器代碼錯誤錯誤

Question

我正在編寫客戶端服務器的網絡編程項目Rock Paper Scissors代碼。我完成了代碼，在測試過程中它運行良好，然後將此行添加到代碼中。

findWinner(gameType,pcChoice); 

當我將代碼行添加到代碼時，代碼開始給我一個關於來自服務器端的分段錯誤的錯誤。這是我添加該行的地方。

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中的一個熟人，不知道該怎麼做。

int pcChoice; 

它是一個整數，以保持一個隨機整數1至3個（巖紙或剪刀）

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)); 

} 

其他事情可能是有問題的是：

嘗試顯式null終止char*

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

你確定玩家從不消極或大於3嗎？

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