Replicate the standard string library function strcpy().
  #include <stdio.h>

void fnstrcpy(char *, char *);

int main(void)
{
char name1[40], name2[40];
clrscr();
printf("Enter a name : ");
gets(name1);

fnstrcpy(name2, name1);

printf("\nname2 = %s", name2);

return 0;
}

void fnstrcpy(char *dest, char *src)
{
for( ; *src != '\0' ; src++)
{
*dest = *src;
dest++;
}
*dest = '\0';
}
