在C中存储令牌字符数组

Question

我在尝试打印一个包含令牌（tok）的字符数组（存储）时遇到了一些问题。每当我打印数组时，我都会得到一个奇怪的符号。

while(1) 
{
    printf("repl>");
    char storage [30];
    char* tok;
    char g;
    char buffer[20];
    int pos = 0, i;
    size_t bufferlength = 20;
    fgets(buffer,sizeof(buffer),stdin);

     tok = strtok(buffer," ");
     while (tok != NULL) 
     {
         storage[pos] = tok;
         tok = strtok(NULL," ");
         pos++;
     }

     printf(" %c\n", storage[0]);
}
