How to print ('0' * 3) as '000' or '9' + '0' = '90' in c++?

Question

1. cout<<'0'*3;

2. string s = "0";
cout<< s*3;

3.char c = '0';
cout<< c*3;

I tried all above things and got huge errors....

Answer 1

std::string has no predefined * operator that will multiply a string by an int, but you can define your own:

but if you want to repeat the character ( char type ) , std::string has a constructor of the form:
"std::string(size_type count, char c);"

Answer 2

I am too naive to understand how made your own string operator but i got the second one...

Thank you :D
