When a dual option selection statement is needed. The program uses an:
If Then Else
If Then
Nested If
None of these are correct
When a single option selection statement is needed, it would be best to use an:

IF-THEN
Nested IF
None of the above
Where more than two options are required in a selection statement, the best approach would be to use a:
IF-THEN-ELSE
IF-THEN
Nested IF
None of the above
What signifies then end of a program?
end
end.
end;
Exit

is a miscellaneous variable
This flowchart is made to ...
find out which of two numbers is the biggest
add two numbers together and output the larger result
input two numbers and expand them
This flowchart has a major flaw. It is
