What is the correct order of steps in an algorithm to add two numbers?

Medium 1 Mark

You need the numbers before you can add them.

A Start > Display Sum > Input A > Input B > Compute Sum > End

B Start > Input A > Input B > Compute Sum > Display Sum > End

C Start > Compute Sum > Input A > Input B > Display Sum > End

D Start > Display Sum > Compute Sum > Input A > Input B > End

2

11

What is a key advantage of an interpreter over a compiler?

Medium 1 Mark

Errors are found immediately line by line with an interpreter.

A Faster execution

B Produces executable files

12

What is a key advantage of a compiler over an interpreter?

Medium 1 Mark

After compiling no translation is needed at runtime.

13

When does a compiler display errors in a program?

Medium 1 Mark

A compiler reads everything first then reports errors.
