Consider the following program: 01 y = input("enter a number")
02 x = y MOD 5
03 if x == 0 then
04 print (True)
05 endif

Which programming constructs are not used in this program?
Selection
Sequence
Iteration

Iteration is not used in the program

Explanation:

Analysing the program one line at a time.

The first two lines are:

y = input("enter a number")

x = y MOD 5

The above lines show a sequential control structure. This is so because the first line is executed before the second (i.e. in sequence).

The third to the last lines are:

if x == 0 then

print(True)

endif

When a program includes at least one if statement or condition, this means that the program contains a selection program control structure.

The above lines may or may not be executed depending on the condition  (if x == 0 then)

If the value of x is 0 then, True will be printed. If otherwise, True will not be printed

The program does not use iteration control structure because no part of the code were looped or repeated.
