Solutions:

The value of x 
 

int x, y = 4, z = 6;
x = (y++) * (++z);

is 28.

y++ evaluates y, then increments it (post incrementation)

++z increments z, then evaluates it (pre incrementation)

so 

y=4, y++

z=6, ++z which will first increase z value from 6 to 7

z=7

x=4*7

x=28

Hope this solution will help.
