strtok函数const char指针错误

Question

我一直收到以下错误

passing argument 1 of 'strtok' discards 'const' qualifier from pointer target type [enabled by default]

通过这一行

for (char *p = strtok(season_info,"\n"); p != NULL; p = strtok(NULL, " "))

ps：season_info的定义如下：  const char * season_info

Answer 1

strtok需要对字符串进行更改，因此无法对const char*参数进行操作。在将该字符串发送到strtok之前，您需要复制该字符串。
