Question

A line in my c++ code reads:

cout<<(i%3==0 ? "Hello\n" : i) ;//where `i` is an integer.

But I get this error:

operands to ?: have different types 'const char*' and 'int

How can I modify the code (with minimum characters)?

Ugly:

i%3==0 ? cout<< "Hello\n" : cout<<i;

Nice:

if ( i%3 == 0 )
   cout << "Hello\n";
else
   cout << i;

Your version doesn’t work because the result types of the expressions on each side of : need to be compatible.
