If int a = 25, b = 5, c = 0; what value is stored in c? When c = a % b;

What is the result of the following in Java statement?

int m=8;
m*=8;
System.out.println("The output =" + m);

int m, p;
m = 5;
p = 0;
p = m-- + --m;

The output will be:

int a=7, p=0, q=0;
p= ++a + --a;
q -= p;

The output of q will be:
