Chapter 4.1, Problem 2SCP

Explanation of Solution

Given value of variables:

int x=4;

int y=-3;

int z=4;

a)

• x == 4:
• result of the given expression is: true
• in this case, the value assigned to x is 4

b)

• x == y
• result of the given expression is: false
• in this case, the value of y is -3 and value of x is 4, which are not the same.

c)

• x == z
• result of the given expression is: true
• in this case both the variables are assigned with the value 4.

d)

• y == z
• result of the given expression is false
• y is assigned with the value -3 and z is assigned with the value 4, which means both are not equal.

e)

• x + y > 0
• result of the given expression is true
• the result of “x+y” is “1” and therefore greater than zero...
