Constantes: Guia para Iniciantes na Programação

Confira como funcionam as constantes na programação!

O que são constantes?

são valores fixos que são atribuídos a uma variável uma única vez. Não pode ser alterada durante o programa.

Como declarar Constantes?

Em linguagens como C, C++ e Java, é necessário usar a palavra-chave "const" antes da declaração da variável.

Exemplo de declaração de constantes:

C: const int Juros = 10; Python: JUROS = 0.1 JavaScript: const JUROS = 0.1

Utilizando Constantes no Código

Constantes não podem ser modificadas. Isso pode causar erros no código se você tentar mudar o valor de uma constante.

Constante e Variável.

A diferença é que variáveis podem ser alteradas em qualquer momento e as constantes não podem ser mudadas.
