函数：

 gets(),puts(),strcat()

strncat(),strcmp(),strncmp()

strcpy(),strncpy()

sprintf(),strchr()

先看gets()和puts()函数吧。

}

 下面再看看还有一些情况要注意的：

char greeting[50] = "Hello, and" "how are" "you" "today!";
这句就是ANSI C会将其串联起来

 还有就是想要输出“的话那么就使用\这个符号

再看一个把字符串看做指针

#include<stdio.h>

int main(void)
{

　　      /*%s格式将输出字符串We，%p格式产生一个地址。*/ 
	printf("%s, %p, %c\n", "We","are", *"space farers");

　　　　　/*这里主要是*后面的那些字符串当做指针，那个就是指向字符串的第一字母，也就是代表第一个字母的地址然后就是取内容了*/
	return 0;
}
