}


老手


#include <stream.h>

const int MAXLEN = 80;

class outstring;
class outstring {
private:

int size;
char str[MAXLEN];

public:
outstring() { size=0; }
~outstring() { size=0; }
void print();
void assign(char *chrs);
};
void outstring::print() {
int in;
for (i=0; i<size; i++)
cout << str[i];
cout << "\n";
}
void outstring::assign(char* chrs) {
int i;
for (i=0; chars[i]!='\0'; i++)
str[i] = chrs[i];
size=i;
}

main (int argc, char **argv) {
outstring string;
string.assign("Hello World!");
string.print();
}
