How can I make a number an object instead of a number in C++?

Question

I want to do this....
int p = 5;
cout << p * 5;

I want the result to be:
55555
How can I do it?

Answer 1

I guess you could make it a string object and overload * to work with strings like you want it to? but this begs the question as to why would you want to do this? couldn't you just make a function like this

string duplicateChar(char toDupe, int times)?

Answer 2

#include <string>
Function:

int join(int a, int b) {
//convert to string
string strA = to_string(a);
string strB = to_string(b);
//back to int
return stoi(strA + strB);
}

int p = 5;
p = join(p, 5);
//55
p = join(p, 5);
//555...

stoi and to_string are in the string library. They convert to and from string.
