Loops

mientras (while)

Executes the block while the condition is true.

// While loop
entero var iterador_mientras = 0
mientras (iterador_mientras < 10) {
    consola.mostrar("Iteration: " + iterador_mientras.texto())
    iterador_mientras++
}

hacer ... mientras (do…while)

Evaluates the condition at the end of the block, guaranteeing at least one execution.

// Do-while
entero var iterador_hacer = 0
hacer {
    consola.mostrar("This message prints at least once.")
    consola.mostrar("Iteration: " + iterador_hacer.texto())
    iterador_hacer++
} mientras (iterador_hacer < 3)

para (for)

Exists in two variants:

1. Classic with initialization, condition, and increment.

   // For loop
   para (entero var i = 0; i < 5; i++) {
       consola.mostrar("For loop, iteration: " + i.texto())
   }

2. Iteration over collections using en or cada.

   // For-in loop
   lista<entero> lista_numeros = [10, 20, 30, 40, 50]
   para (entero var valor_numero en lista_numeros) {
       consola.mostrar("Current value: " + valor_numero.texto())
   }
   
   // For-each loop
   para (entero var valor_numero cada lista_numeros) {
       consola.mostrar("Current value: " + valor_numero.texto())
   }

Both forms create a new scope for loop variables.

Loop Control

• romper (break): terminates the current loop.
• continuar (continue): skips the current iteration and evaluates the next one.

// Exit any loop with 'romper'
entero var contador = 0
mientras (contador < 10) {
    consola.mostrar("Counter: " + contador.texto())

    si (contador == 5) {
        consola.mostrar("Counter reached 5, exiting loop!")
        romper
    }

    contador++
}

Recommendations

• Avoid infinite loops by verifying that the condition changes in each iteration.
• Use list methods (sumar, promedio, buscar) when they simplify code instead of manual iterations.
• If you need to accumulate results, initialize variables outside the loop and document the intent with brief comments.
