Go by Example

Example

  • Only looping construct
  • Same as in C

// for is Go’s only looping construct. Here are three basic types of for loops.

// The most basic type, with a single condition.
i := 1
for i <= 3 {
  fmt.Println(i)
  i = i + 1
}
// A classic initial/condition/after for loop.
for j := 7; j <= 9; j++ {
  fmt.Println(j)
}
// for without a condition will loop repeatedly until you break out of the
// loop or return from the enclosing function.
for {
  fmt.Println("loop")
  break
}
// You can also continue to the next iteration of the loop.
for n := 0; n <= 5; n++ {
  if n%2 == 0 {
    continue
  }
  fmt.Println(n)
}
