if then Ternary Operator in C++ [duplicate]

  c++, visual-c++

I need to confirm this but is it possible to have a Ternary Operator in an if-then statement in C++ without the else?

For example:

if (ShowDebug) 

… would be:

ShowDebug ? DebugRender(); 

… but I get a:

error C2059: syntax error: ';'

… then I thought maybe I could avoid a compiler error with having the right syntax but nothing in the else part:

ShowDebug ? DebugRender():; 

… and I still get a:

error C2059: syntax error: ';'

Any suggestions? Or is it simply not supported?
