Assignment in PSeInt: what the <- arrow means

Stores a value in a variable. Read the arrow <- as "gets": the right side is worked out first and the result goes into the box on the left, replacing whatever was there.

Worked example

A complete algorithm, ready to copy and run.

Algoritmo Example    puntos <- 10    puntos <- puntos + 5    Escribir puntosFinAlgoritmo

Output

puntos ends up as 15.

This is what the console shows when the example runs.

15

Common mistake

It isn't a maths equation: puntos <- puntos + 5 means "add 5 to puntos".

Good to know

Besides <-, := is accepted too. Some profiles also let you assign with =, but <- avoids mixing it up with a comparison.

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.

puntos ← puntos + 5
In the flowchart. Flowchart: a process rectangle reading "puntos ← puntos + 5", with one arrow in and one arrow out.
