偶数和奇数的数组

Question

我有一个问题，请帮我创建2 array s。
1）偶数阵列
2）奇数阵列

在拉布勒我看到一切正常。阵列很好。但它们并非如我所料。

和阵列2

我的阵列码是

for (indexi = 2; indexi < masivi1.Length; indexi = indexi + 2) 
{ 
    masivi1[indexi] = indexi; 

} 
for (k = 2; k < masivi1.Length; k = k + 2) 
{ 


    label2.Text += masivi1[k].ToString; 
} 

第二阵列

for (indexi1 = 0; indexi1 < masivi2.Length; indexi1++) 
{ 
    if (indexi1 % 2 != 0) 
    { 
     masivi2[indexi1] = indexi1; 
    } 
} 
for (k1 = 0; k1 < masivi2.Length; k1++) 
{ 
    if (k1 % 2 != 0) 
    { 
     label3.Text += masivi2[k1].ToString() + " | "; 
    } 
} 

有人可以帮助解决显示正确地创建数组作为

2,4,6 ...
1,3,5 ......

Answer 1

您可以填写两个数组奇数，偶数这样

var evenArray = new int[10]; 
var oddArray = new int[10]; 

for (int i = 0, even = 0; i < evenArray.Length; i++, even += 2) 
{ 
    evenArray[i] = even; 
} 

for (int i = 0, odd = 1; i < oddArray.Length; i++, odd += 2) 
{ 
    oddArray[i] = odd; 
} 

产品

evenArray = [ 0, 2, 4, 6, 8, 10, 12, 14, 16, 18 ] 
oddArray = [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 ] 

Answer 2

不知道你正在尝试实现但这看起来错误：

for (indexi = 2; indexi < masivi1.Length; indexi = indexi + 2) 
{ 
    masivi1[indexi] = indexi; 
} 

因为你只把东西放到每第二个数组元素，即2，4，6，...

也许这是你想要什么：

for (indexi = 0; indexi < masivi1.Length; ++indexi) 
{ 
     masivi1[indexi] = 2*indexi + 2; 

} 

第二个数组有同样的问题：

for (indexi1 = 0; indexi1 < masivi2.Length; indexi1++) 
{ 
     if (indexi1 % 2 != 0) // This line means that you only put 
           // elements in the array when index1 = 1, 3, 5, ... 
     { 
      masivi2[indexi1] = indexi1; 
     } 
} 

Answer 3

for (int indexi = 0; indexi < masivi1.Length && indexi < masivi2.Length; ++indexi) 
{ 
    if (indexi % 2 == 0) 
    { 
     masivi1[indexi/2] = indexi; 
    } 
    else 
    { 
     masivi2[indexi/2] = indexi; 
    } 
}
