mystrcpy 的两种方式

#include <string>
#include <iostream>
using std::cin;  
using std::cout;
using std::endl;
using std::string;
void mystrcpy(char *to,char *from)
{
     for(;*from!='\0';from++,to++)
     *to = *from;
     *to='\0';
}
void mystrcpy1(char to[],char from[])
{
     int i=0;
     for(;from[i]!='\0';i++)
     {
        to[i] = from[i];              
     }
     to[i]='\0';
}
int main()
{
    char s2[] ="abcdefg",s1[1000];
    cout<< strlen(s2)<<endl;
    //mystrcpy(s1,s2);
    mystrcpy1(s1,s2);
    puts(s1);
    system("pause");
    return 0;  
}
