一个字符串压缩程序，将字符串中连续出席的重复字母进行压缩，并输出压缩后的字符串

通过键盘输入100以内正整数的加、减运算式，请编写一个程序输出运算结果字符串。输入字符串的格式为：“操作数1 运算符 操作数2”，“操作数”与“运算符”之间以一个空格隔开

#include#includechar a[]={'a','b','a','c','a','c','d','e','k','b'};typedef char key_type;typedef struct node{ key_type key; struct node *next;}node, *pnode;void insert(pnode *root, key_type k

【指针*与&】指针和数组有异曲同工之妙，在前面博客有专门解释过，指针声明用*，凡是在声明一个变量前面加上这个符号，就是说明声明的这个变量是一个指针，它是一个地址，比如：int a = 2;int *p;p = &a;p就是一个指向整型变量的指针，p指向的是整型变量a的地址，而*在使用的时候还有一个别名，解引用，抵消了&引用功能，&在这里是引用a的地址。*p = 1;//其实*p = *(&a)

首先需要先了解结构体的基本知识： 1.结构体定义： struct 结构体名 ｛ ……结构体成员； ｝ 举例：struct student{ char name[10]; int age;}2.结构指针-struct *p 其中，p为指向结构的一个指针，在给p传地址时，要给他传入结构体类型的地址。 举例：struct student *p;st
