Is there a roman numeral for the number zero?

Why does my C++ output doesn't convert a number into a roman numeral?

• include <iostream> #include <string> using namespace std; int main() { int number; string numeral; cout<<"Enter a number: "; cin>> number; if(number ==1) numeral = "I"; else if (number ==5) numeral = "V"; else if (number ==10) numeral = "X"; else if (number ==50) numeral = "L"; else if (number ==100) numeral = "C"; else if (number ==500) numeral = "D"; else if (number ==1000) numeral = "M"; return 0; }

• Answer:

  Add the following line to your program before the "return 0" cout << number << " in Roman is " << numeral << endl;
