Which is faster?

>Which is faster? Post Increment or assignment? Why?

Given two tasks, A and B, the C standard does not guarantee anything
about the relative speed of the two, even if B is "repeat A one
billion times". The result is also likely to depend on the instruction
set of the target machine, and the optimization settings of this
invocation of the compiler.

In the case of post increment vs. assignment, it does matter
whether the resulting value is used. The code for:
p++;
vs.
p += 1;
is hopefully identical. However, identical code does not guarantee
identical performance, as the prior state of the cache and execution
state of the processor may change that time.

Those things belong to someone else, and scams with Paypal do
not entitle you to take them.

See those semicolons? They are in there for a reason.
You can't use the value of p++; , an expression like foo(p++;)
won't compile.

Please explain how you can use the value with the semicolons left in.
