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<stdio.h>

#include<string.h>

#include<stdlib.h>

/*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。

/* HELLO.C -- Hello, world */
