What is programming?

program = data structures + algorithm

The first algorithm does not have to be the best. Think of problem solving as a series of iterative improvements.

Computer programming as manipulating information in memory (analogous to boxes)

Physical demonstration of the technique of swapping two variables with the use of a temporary variables.

Lab
