error: too few arguments to function 'char* gets_s(char*, rsize_t)'|

这个错误是因为你调用了gets_s函数，但是没有传入足够的参数。gets_s函数是一个安全的读取字符串函数，需要传入两个参数，第一个参数是一个字符型数组指针，用于存储读取到的字符串，第二个参数是一个rsize_t类型的整数，用于指定读取的最大长度。你需要确认你的函数调用中是否传入了这两个参数，并且第二个参数的值是否合理。同时，建议使用更安全的替代函数fgets()。

my_sql.c:6:24: error: too few arguments to function ‘mysql_real_connect’ 6 | MYSQL* mysql = mysql_real_connect(NULL,"192.168.0.249","root","LZGlzg,199228","mydb",3306,NULL); | ^~~~~~~~~~~~~~~~~~ In file included from my_sql.c:2

这个错误提示是因为 `mysql_real_connect` 函数的参数不足导致的。它需要传递的参数如下：

`mysql_real_connect(MYSQL *mysql, const char *host, const char *user, const char *passwd, const char *db, unsigned int port, const char *unix_socket, unsigned long clientflag)`

所以你需要检查一下你调用 `mysql_real_connect` 函数时传递的参数是否正确，尤其是最后一个参数 `clientflag` 是否传递了正确的值。如果你仍然无法解决问题，可以贴出你的代码让我帮你检查。

too many arguments to function 'char* malloc()'

This error message typically occurs when you are trying to allocate memory using the malloc() function and you are passing too many arguments to the function.

The malloc() function takes only one argument, which is the size of the memory block you want to allocate in bytes. If you pass more than one argument, you will get this error.

For example, if you try to allocate memory like this:

char* str = malloc(100, sizeof(char));

You will get the "too many arguments" error because you have passed two arguments to the malloc() function.

To fix this error, simply pass only the size argument to the malloc() function like this:

char* str = malloc(100 * sizeof(char));

This will allocate 100 bytes of memory for the string.
