El lenguaje de programación Go permite usar un bucle dentro de otro bucle. La siguiente sección muestra algunos ejemplos para ilustrar el concepto:
Sintaxis
La sintaxis de un nested for loop declaración en Go es la siguiente:
for [condition | ( init; condition; increment ) | Range] {
for [condition | ( init; condition; increment ) | Range] {
statement(s);
}
statement(s);
}
Ejemplo
El siguiente programa usa un bucle for anidado para encontrar los números primos del 2 al 100:
package main
import "fmt"
func main() {
/* local variable definition */
var i, j int
for i = 2; i < 100; i++ {
for j = 2; j <= (i/j); j++ {
if(i%j==0) {
break; // if factor found, not prime
}
}
if(j > (i/j)) {
fmt.Printf("%d is prime\n", i);
}
}
}
Cuando el código anterior se compila y ejecuta, produce el siguiente resultado:
2 is prime
3 is prime
5 is prime
7 is prime
11 is prime
13 is prime
17 is prime
19 is prime
23 is prime
29 is prime
31 is prime
37 is prime
41 is prime
43 is prime
47 is prime
53 is prime
59 is prime
61 is prime
67 is prime
71 is prime
73 is prime
79 is prime
83 is prime
89 is prime
97 is prime
