A 'C' Compiler should break down the elements of the 'for' statement into logical parts.

Assuming the following items are to be used...

#define X x=0
#define Y x<5
#define Z x++
#define F x+=2

The following 'for' statement...

for (X; Y; Z)
{
F;
}


is identical (logically) with...

X;
while (Y) {
F;
Z;
}
