Write a program to implement following main() function:

int main() { string str2(“MCKVIE”);string str3=str2;cout<<str3; return 0; }

#include<iostream.h>
#include<conio.h>
#include<string.h>

 class string{
public:
char str[100];
string(char *);
string operator=(const string);
friend ostream &operator<<(ostream &output,const string s){
output<<s.str<<endl;
return output;
}
};

string::string(char *s){
strcpy(str,s);
}
string string::operator=(const string s){
string s1("");
strcpy(s1.str,s.str);

return s1;
}

void main()
{
  //  int a=0;
    string str2("MCKVIE");
    string str3=str2;
    clrscr();
    cout<<str3;
    getch();
}
