PSeInt Dimension: how to create an array

Creates an array: a row of numbered boxes sharing one name. Use it when you need to keep many values of the same kind, like a class's grades, without inventing a variable for each.

Worked example

A complete algorithm, ready to copy and run.

Algoritmo Example    Dimension notas[5]    notas[1] <- 18    Escribir notas[1]FinAlgoritmo

Output

Creates 5 slots (notas[1] to notas[5]) and stores 18 in the first.

This is what the console shows when the example runs.

18

Common mistake

Depending on the profile, slots start at 1 or at 0.

Some details depend on your school's profile. See the language profiles.

In a flowchart

This is how it appears in a flowchart, with the same shapes Codoritmo draws.
