这个自定义菜单应该没有那么难弄吧?首先你要有这个权限,认证的订阅号和服务号吧。后来我用的侯斯特,特别省事就创建好了。

方法是在定义变量的同时给其一初始值。结构体变量的初始化,遵循相同的规律。 简单变量的初始化形式如下: 数据类型 变量名=初始化值; 例如,定义整型变量a,并给其初始化值10的语句如下 int a=10; 数组的初始化,需要通过一常量数据列表,对其...

定义了char number[3],所以只保存前三个字符,而你printf时却要输出6个,就连名字那前三个字符也输出了。比如第一个信息,学号只存成了B13,后面写的没有存入,姓名存了SDF,因为name跟在number之后,所以你在输出六个字符,就成了B13SDF

typedef struct { student stu[listsize]; int length; }sqlist; int isEqual(const student *st0,const student *st1) /* 比较函数 */ { if(st0->num!=st1->num){return 0;} if(0!=strcmp(st0->name,st1->name))return 0; if(st0-> gender!=st1...

struct student { student(); char number[10]; char name[31]; float math; float english; }; student::student() { cout number >> name >> math >> english; } int main() { student stu; stu.math = 0.6*stu.math; stu.english = 0.4*stu.e...
