Question

Write assignment statements that perform thefollowing operations with the variables a, b, and c.
a) Adds 2 to a and stores theresult in b.
b) Multiples b times 4 andstores the result in a.
c) Divides a by 3.14 and storesthe result in b.
d) Subtracts 8 from b andstores the result in a.

Answer 1

Answer:

An assignment statement's overall syntax is-

                   variable = expression ;

Where the variable must be declared; the variable may be a simple name, or an indexed location in an array, or an object's field (instance variable) or a class static field; and the expression must result in a value that is compatible with the variable type. In other words, it must be feasible to cast the expression to the variable type.

Examples: int i =4;

a) b=(a+2);

(a+2) is the expression for adding 2 to a, whereas b equal to the result of (a+2).

b) a=b*4;

(b*4) is the expression for multiples b times 4,whereas a equal to the result of (b*4)

c) b=(a/3.14)

(a/3.14) is the expression for divides a by 3.14,whereas b equal to the result of (a/3.14)

d )a=(b-8)

(b-8) is the expression for Subtracts 8 from b,whereas a equal to the result of (b-8)
