See, if prefix and postfix (x++, --x) are nothing , they are just increasing the value by one or decreasing the value by one. prefix: ++x: it means the value of x increase by one first than we perform the calculation ex: x=0 ; y=2+(++x); the y=3 and x=1; x++: it means you do calculation first then increase the value of x by one ex: x=0; y=2+(x++); y=2 and x=1; same for decrement: --x: it means first decrease x by one then perform the calculation : ex: x=2; y=2+(--x) ; then y=3 and x=1; x--; it means first perform the calculation and then decrease the value by one: ex: x=2; y=2+(x--) then y=4 and y=1; I hope you got it.

Then clarify your problem, try doing it yourself, and ask for help when you will have tried solving it yourself
