which is faster ?++ or +

which one of the following will execute faster?
int p=2;
p++; OR p=p+1;OR p+=1;


and y??
is it p++ bcoz it is a single instruction??...nd the rest r multiple...

yes, from microprocessor point of view short instructions are likely to execute faster but if the instructions is expanded to the actual form and then converted to assembly code then I think there will not be any diff in the execution...
