Rewrite the following expressions as C++ assignment statements that use the conditional operator. (Assume that all variables are declared properly.)

 

//a.

  if (x > y)

    z = x - y;

  else

    z = y - x;

 

 

//b.

  if (hours >= 40.0)

    pay = 40 * 7.50 + 1.5 * 7.5 * (hours - 40);

  else

    pay = hours * 7.50;

 

 

//c.

  if (points >= 60)

    str = "Pass";

  else

    str = "Fail";

Expert Solution
Step 1

The syntax of the conditional operator is as follows:

Expression1 ? Expression2 : Expression3

If Expression1 is true, then Expression2 is evaluated else Expression3 is evaluated.

a. Write the assignment statement for given statements as follows:

z = ( x>y ? x-y : y-x);
