Question

Which statement is generally false?

a. Statements preceding a for and statements in the body of a for should typically be merged into the for header.

b. Limit the size of control statement headers to a single line, if possible.

c. Initialization of a for loop control variable can occur before the for loop executes and not in the loop itself.

d. The increment portion of a for header can be a decrement.

Answer 1

Answer:       (a)   Statements preceding a for and statements in the body of a for should typically be merged into the for header.

Reason:       Statements in the body of for can never be merged into the for the header. The body of the for is enclosed within {} and can be not written somewhere else.

Also,       (b)   Limit the size of control statement headers to a single line, if possible.
           It is possible, this is why for loop can be implemented in a single line.

       (c)   Initialization of a for loop control variable can occur before the for loop executes and not in the loop itself.
           It is also true, loop variable can be initialized before the loop starts.

       (d)   The increment portion of a for header can be a decrement.
           It is also true, by changing the update expression in a loop.
