Can I extend conditional expression in C++

Can I make conditional expression with more than one else if:

Casual condition:

int number = 50;
if (number > 23) cout << "The variable number is greater then 23 " << endl;
else cout << "23 is greater then variable number"  << endl;

Conditional expression:

 int number = 50;
 cout << (number > 23 ? "The variable number is greater then 23 " : "23 is greater then variable number")<< endl;

Is it possible to add more "else if" in this second case or it's only possible to add one condition consisting from "if and else"

No there's no way to have an else-if in an inline conditional ('?:' syntax). You could maybe approach this with nested '?:s' with parentheses, but it'd be ugly.

Edit: looking at the other answer, i guess you can and it's not that ugly! But I haven't seen this pattern in practice.

Similar to an else if, you could just have the else case be another conditional:

condition1 ? val1 :
condition2 ? val2 :
condition3 ? val3 :
val4

which is kind of equivalent to

if (condition1)
    val1
else if (condition2)
    val2
else if (condition3)
    val3
else
    val4
