Count--;

}

printf("删除成功!\n");
}

在index=search_salary(salary,name);这里错

Answer 1

在index=search_salary(salary,name);这里错
这比较明显了，你都说了是上面的地方出错，index是int类型的，而函数search_salary(salary,name);是定义成void类型的了，所以会出错。把函数search_salary(salary,name)定义成int类型，具体自己实现。

Answer 2

void search_salary(struct salary_list salary[],char*name);函数没有返回值，怎么能用index来接收函数返回值呢。
