strcpy.c

几个C++库函数,也是经常用来测试编程实力的函数!

///////    Copying strings    ///////
#include <iostream>
#include <string.h>
char *strcpy(char *s, const char *cs)
{    char *tmp;
     tmp = s;
     while (*cs != '\0')
             *tmp++ = *cs++;
     *tmp = '\0';
     return s;
}

int main()
{    char a[]="abcdef";
     char b[7];
     strcpy(b,a);
     std::cout << "len=" << strlen(a);
     std::cout << "copy is " << b << std::endl;
     return 0;
}
