Para que serve o laço de repetição foreach? Essa estrutura é utilizada para iteração de listas, ou seja, é uma estrutura simplificada do laço for quem tem por objetivo tornar o código mais legível e a codificação mais rápida.

Ainda que a estrutura foreach facilite a codificação, em relação a performance nada se altera. Isso porque, a estrutura foreach, nos bastidores, funciona de maneira análoga a estrutura "for". Logo, a única diferença está na forma como codificamos e não na forma como o código é executado.
