Programming Languages
The following samples demonstrate the differences in programming languages for a similar function: an input, n, is requested from the user (defining the number of entries in a list); the program loop repeats itself n times, asking for an entry and comparing it with the current biggest number entered. The biggest entry entered is then displayed on screen.
