The number in parentheses at the end of an exercise refers to the learning objective listed at the beginning of the chapter.

Write C++ statement(s) that accomplish the following: (6, 7)

a. Declare int variables x and y. Initialize x to 25 and y to 18.

b. Declare and initialize an int variable temp to 10 and a char variable ch to 'A'.

c. Update the value of an int variable x by adding 5 to it.

d. Declare and initialize a double variable payRate to 12.50.

e. Copy the value of an int variable firstNum into an int variable tempNum.

f. Swap the contents of the int variables x and y. (Declare additional variables, if necessary.)

g. Suppose x and y are double variables. Output the contents of x, y, and the expression x + 12 / y - 18.

h. Declare a char variable grade and set the value of grade to 'A'.

i. Declare int variables to store four integers.

j. Copy the value of a double variable z to the nearest integer into an int variable x.
