11.1 字符串和指针

关于指针输出字符串

const char *p = "something is pointing at me.";puts(p);

将字符串看作指针

#include<stdio.h>int main(){    printf("%s  %p  %c\n","we","are",*"space farers");}//输出we 0x100000f61 s

使用指针表示法创建字符串

const char *p = "something is pointing at me .";//下面的声明和上面几乎相同const char ar1[] = "something is pointing at me .";

数组和指针的区别、数组名heart 是常量，指针名head 是变量（壳进行递增操作）

char heart [] ="i love you !";const char *head = "i love you !";//使其等价head=heart;

指向字符串的指针数组和char类型数组的数组

const char *myarray[LIM]={"adding number swiftly","understanding ins"};char youarray[LIM][SLEN]={"walking in a straight line","sleeping letters"};
