应该是strncpy(a,b,7)吧.
复制b中的前7个字符到a中

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

void main( void )
{
char string[100] = "Cats are nice usually";
printf ( "Before: %s\n", string );
strncpy( string, "Dogs", 4 );
strncpy( string + 9, "mean", 4 );
printf ( "After: %s\n", string );
}

Output

/* STRCPY.C: This program uses strcpy
* and strcat to build a phrase.
*/

#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 );
}

Output

String = Hello world from strcpy and strcat!
