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"
};
