while loop

Go doesn’t have while loops because they can be written as for loops.

For example, this C++ while loop:

    int n = 0;
    while (n < 3) {
        printf("n: %d\n", n);
        n++;
    }

can be written as for loop:

main.go

	n := 0
	for n < 3 {
		fmt.Printf("n: %d\n", n)
		n++
	}

Output:

n: 0
n: 1
n: 2

A more concise version:

main.go

	for n := 0; n < 3; n++ {
		fmt.Printf("n: %d\n", n)
	}

Output:

n: 0
n: 1
n: 2
