strcpy 与 strcat的用法

[110199]

大家好，我在vc自带的帮助MSDN中找stract 与strcpy的用法，根据我的理解strcpy(a,b)就是把b的内容拷贝到a中，那么strcat(）的用法呢？？
------------------------------------------------------------------------
我在vc自带的帮助MSDN中找stract 与strcpy的用法，并且运行了MSDN自带的例子
#include <string.h>
#include <stdio.h>

void main( void )
{
char string[80];
strcpy( string, "Hello world from " );
strcat( string, "strcpy " );
strcat( string, "and " );
strcat( string, "strcat!" );
printf( "String = %s\n", string );
}
---------------------------------------------
运行时出错
D:\myproject\example\example.cpp(6) : error C2065: 'strcpy' : undeclared identifier
D:\myproject\example\example.cpp(7) : error C2065: 'strcat' : undeclared identifier
Error executing cl.exe.

example.obj - 2 error(s), 0 warning(s)

------------------------------------------------

我的问题是1.stract 与strcpy的用法(重点是strcat)
2.运行时出错信息说strcpy,strcat末定义，我应在哪定义呀？？

你是 vc几啊，是不是.net？

我vc++6可以的。

1.stract 与strcpy的用法(重点是strcat)

怎么用我觉得还是自己去测试一下比较好。


2.运行时出错信息说strcpy,strcat末定义，我应在哪定义呀？？

strcpy( string, "Hello world from " ); //string为"Hello world from "
strcat( string, "strcpy " );//string为"Hello world from strcpy"
strcat( string, "and " );//string为"Hello world from strcpy and "
strcat( string, "strcat!" );//string为"Hello world from strcpy and strcat"

[闻缺陷则喜何志丹]

strcpy( string, "Hello world from " ); //string为"Hello world from "
strcat( string, "strcpy " );//string为"Hello world from strcpy"
strcat( string, "and " );//string为"Hello world from strcpy and "
strcat( string, "strcat!" );//string为"Hello world from strcpy and strcat"

strcat是将一个字符串加到一个字符串后,得到一个新的字符串.
如:
strcpy( string, "Hello world from " );
strcat( string, "strcpy " );

strcpy相当于给字符串变量赋值.
字符串开始是"Hello world from " ,strcat函数将"strcpy " 加到其后,得到新的字符串
"Hello world from strcpy "
