本文演示了如何使用strcpy和strcat函数来构建一个完整的字符串。通过具体的C语言代码示例，展示了这两个函数的基本用法及注意事项。

strcat is short for string catenate.

// crt_strcpy.c
// compile with: /W1
// This program uses strcpy
// and strcat to build a phrase.

#include <string.h>
#include <stdio.h>

int main( void )
{
   char string[80];

   // Note that if you change the previous line to
   //   char string[20];
   // strcpy and strcat will happily overrun the string
   // buffer.  See the examples for strncpy and strncat
   // for safer string handling.

   strcpy( string, "Hello world from " ); // C4996
   // Note: strcpy is deprecated; consider using strcpy_s instead
   strcat( string, "strcpy " );           // C4996
   // Note: strcat is deprecated; consider using strcat_s instead
   strcat( string, "and " );              // C4996
   strcat( string, "strcat!" );           // C4996
   printf( "String = %s\n", string );
}
