3.7.8 Conditionals
The middle operand in a conditional statement can be omitted, if the result is to be the
same as the test, for example:
i i : j;
This is most useful if the test modifies the value in some way, for example:
i++ : j;
where i++ comes from a macro. If you write code in this way, then i++ is evaluated only
once.
If the original value of i is nonzero, the result is the original value of i. Regardless of
this, i is incremented once.
3.7.9 Initializers
As in standard C++ and ISO C99, the elements of an aggregate initializer for an
automatic variable are not required to be constant expressions.
Mode
Supported in GNU mode only for C90.
Example
float Initializers_0 (float f, float g)
{
float beat_freqs[2] = { f-g, f+g };
float aLocal;
int i=0;
}
for (; i
