The use of if - else if - else decision construct & importance of planning using examples in coding
The if ... if else ... else decision construct and the need for working out the logic of algorithms through well known examples (in this case, a football scoreline).
A football scoreline has three possible outcomes, so using the if ... if else ... else we can decide this.
Again, there is annotation and please pause the video to read.
