Computer Science for IGCSE & O level - Algorithm Design And Problem Solving (Section 6 - No. 43)
What is the difference between an algorithm and a program?
They are the same thing.
An algorithm is written in machine code, while a program is not.
An algorithm is the design or blueprint, and a program is the implementation of that design.
A program is written to run the algorithm.
Explication
An algorithm is the design and a program is the implementation.
