用C语言编写一个通讯录管理系统

C语言编写一个通讯录管理系统的源代码如下：

#include<stdioh>

#include<stringh>

#include<stdlibh>

/定义保存通迅录的信息/

structfriends

{

charname[20];/名字/

charprovince[20];/省份/

charcity[20];/所在城市/

charnation[20];/民族/

charsex[2];/性别M/F/

intage;/年龄/

}

扩展资料

1、在C++中应该使用inline内连函数替代宏调用，这样既可达到宏调用的目的，又避免了宏调用的弊端。

2、在C语言两个函数的名称不能相同，否则会导致编译错误。在C++中，函数名相同而参数不同的两个函数被解释为重载。

3、在大型程序中，使函数名易于管理和使用，不必绞尽脑汁地去处理函数名。

这是我以前写的一个串口通讯文件，全部贴出来了，希望对你有帮助，包括设置，发送，接受数据，你可以好好看看，祝你成功
