Let me make this more clear... infact if the case is of
pre-increment:

1- find all the variables of pre-increment, and compute them
2- do the assignment.

for example, what I do:
main()
{
int a=1; // initialization
int b=0; // initialization

b=++a + ++a; // find the pre-increment i.e. 2 increments of
'a' so now 'a' in this step will be incremented by 2 so now
'a' will contain 1+2=3. so now a=3. Again before assignment
compute 'a+a' which is '3+3'=6

printf("%d %d",a,b); //3 6

}

Just a trick:- always compute the pre-increments in the same
step...

If I say b= ++a + ++a; answer is 3 and 6
If I say b= ++a + a++; answer is 3 and 4 because in this
line one pre-increment is there. So now '++a + a++'= "2 + 2"



Thanks!!
