6.5) Understanding Arrays (cont’d)
Now, this allows you to use variables called person(1), person(2) and person(3) in place of persona, personb, and personc , respectively. For example, you can read in the values from the keyboard to the different variables as:
read *, person(1) read *, person(2) read *, person(3)
Then you could output the values to a file as:
open(33, file=’outputheights.dat’) write(33,*) person(1) write(33,*) person(2) write(33,*) person(2)
Loops and arrays together bring real power into programs so let us now put aside arrays for a minute and look at loops and then after that we will join up loops and arrays.
