public:

{
cout<<"\n\nEnter the string : ";

mystring operator+(mystring);
void disp()
{
cout<<str;
}
};

mystring mystring::operator +(mystring s)
{
mystring temp;

cout<<"\n\nFirst string is  : ";
str1.disp();
cout<<"\n\nsecond string is : ";
str2.disp();
cout<<"\n\nConcatination of two string is : ";
