Explain statement in C++?

Question

I don't known the statement:
(a>b?a>c?a:c:b>c?b:c)

Thanks in advances.

Answer 1

Very interesting!

(a > b) ? ( (a > c) ? a : c ) : ( (b > c) ? b : c )

Expanding:

(a > b) ?
(a > c) ?
a
:
c
:
(b > c) ?
b
:
c

Equivalent:

if (a > b)
if (a > c)
a
else
c
else
if (b > c)
b
else
c

Always wrap the related blocks in parenthesis to make it readable.
