1. C语言动态分配二维数组 
(1)已知第二维Code-1
char (*a)[N];//指向数组的指针 


a = (char (*)[N])malloc(sizeof(char *) * m); 
printf("%d/n", sizeof(a));//4，指针 
printf("%d/n", sizeof(a[0]));//N，一维数组 


free(a);

一、RTP 是进行实时流媒体传输的标准协议和关键技术
实时传输协议（Real-time Transport Protocol，PRT）是在 Internet 上处理多媒体数据流的一种网络协议，利用它能够在一对一（unicast，单播）或者一对多（multicast，多播）的网络环境中实现传流媒体数据的 实时传输。RTP 通常使用 UDP 来进行多媒体数据的传输，但如果需要的话可以使用 TCP 或者 ATM 等其它协议。

相同点：
1，无论是文本传输还是二进制传输，其实均是将被传输对象转化为二进制字节进行传输的，很多人认为文本传输，顾名思义，就是网络直接传输文本，，，，这是不对的。。。。。
2，无论是文本传输还是二进制传输，均是需要有一定的编码方式的。如果一个被传输对象是utf8格式的字符串，那么无论是文本传输还是二进制传输给客户端，客户端解析也必须使用utf8进行decode来获得该字符串。
 
不同点：
