关于使用c++定义学生对象数组问题，懂的大佬速来~

Question

定义一个学生类，学生包含的特征信息有学号、姓名、性别和年龄等；功能（函数）包括获取学生姓名、性别和年龄等。在主函数中定义学生对象数组（长度不少于5），分别统计男生的平均年龄和女生的平均年龄（借助指针），并输出。请示范一下
分3部分 头函数
功能函数
主函数

Answer 1

class student{public：char *xuehao;char *name;char *sex;int age;public:char *getName(char *xuehao){return .......}char *getSex(char *xuehao){return .......}int getAge(char *xuehao){return .......}}
