Variables in PSeInt: examples to get started

3 examples

How it works

A variable is a named place where the program keeps a value to use later: an age, a price, a name. You can change its value as often as you like; the variable always remembers the latest one.

Definir says what kind of data it will hold: Entero for whole numbers, Real for numbers with decimals, Caracter for text and Logico for true or false. Depending on your school's profile, Definir may be required.

To store a value you use the <- arrow, read as "gets". The right-hand side is worked out first, so total <- total + precio means "add the price to total".

Short example

The least you need to see it work. Copy it or open it in the editor.

Algoritmo Variables    Definir precio, total Como Real    Definir cantidad Como Entero    precio <- 2.5    cantidad <- 4    total <- precio * cantidad    Escribir "Total to pay: ", totalFinAlgoritmo

What it prints:

Total to pay: 10
