Question

我需要在数组中显示偶数（在Psuedocode中），我完全不知道如何做到这一点。

据我所知：

Begin write_evens(in numbers As Array of Integers, in array_size As Integer)
    Declare count As Integer
    Set count ← 0
While count < size
*******I'm stuck on what to do in the loop*****
Set count ← count + 1

{编辑}

我在这里：

Begin write_evens(in numbers As Array of Integers, in array_size As Integer)
    Declare count As Integer
    Set count ← 0
    While count < size
    If array_size % 2 == 0 
    Write array_Size
End if
    Set count ← count + 1
End

Answer 1

使用modulo来测试数字是否均匀。所以类似于：print＆lt; - 如果MOD（numbers [count]）== 0

Answer 2

这是一些应该按要求做的伪代码。如果您需要任何澄清，请与我们联系。

function write_evens(A array of integers)
    int i = 0;
    while i < A.length
        if (i%2 == 0)
           print A[i] + " "
        i++
