Question 1 edit

Assume that w=6, x=10, y=6 and z=3. What are the truth values of the following statements?

w<9
w!=y
z>x
z<=y
x-6>y*2

Question 2 edit

With the same values of w,x,y and z, what are the values of the following combinations?

w<9 && w!=y
x+7>2 || x==6
!(x-9>1)
!((x>y) && (x<z))
(x>7) && !(x>7)
(x>7) || !(x>7)

Question 3 edit

Under what values of x, y, and z do the following numbered statements get executed? Give the answers in forms like x>y>z.

if(x==y){
  statement 1;
  statement 2;
}
else if(y>z){
  statement 3;
  if(x==z){
    statement 4;
    if(y<z){
      statement 5;
    }
  }
}
else{
  statment 6;
}

Question 4 edit

Under what values of x do the following numbered statements get executed?

switch (x){
case 0:
  statement 1;
  break;
case 1:
  statement 2;
case 2:
  statement 3;
case 4:
