#include <stdio.h>
#include <string.h>

void trim(char * str1)
{
    char *temp = (char *)str1;
         if(temp)
         {
               temp++;
         }
    return ;
}

void main()
{
    char *str = "yinlang";
    printf("str = [%s]\n", str);
    trim(str);
    printf("str = [%s]\n", str);
}
我想要的结果是
str = [yinlang]
str = [inlang]
但是实际的结果是
str = [yinlang]
str = [yinlang]
为什么，怎么才能我要的答案呢，trim的返回值还必须是void；请高手帮忙！
