Split an Array Like below

Pruthvi Patel

This is different than previous uploaded question please see carefully.

I have one array called ans[i].

ans[i]={1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16} //n no.of inputed element.Not fix array

and i want to split in group of 3 and stored it in array.

Like this if x=2 the it should store the summation of 1+4+7+10+13..like below.

res[0]= 35 //1+4+7+10+13

res[1]=40 //2+5+8+11+14

res[2]=45 //3+6+9+12+15

if x=3 then,

res[0]=1+5+9+13

res[1]=2+6+10+14

res[2]=3+7+11+15

res[3]=4+8+12+16

if x=1 then

res[0]=1+3+5+7+9+11+13+15

res[2]=2+4+6+8+10+12+14+16

if x=4,5... for n no of input for n size of an array.

please give code for this.

Hello Parthiv,
You can use code.
int[] marks = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };
List list = new List();
int rArrray = Convert.ToInt32(textBox1.Text); // textBox1.Text is your number
int looplen= marks.Length/(rArrray+1) ;
looplen=looplen*(rArrray+1);
num2 = 16 / 3;
int j = 0;
for (int i = 0; i < rArrray+1; i++)
{
int num1 = 0;
j = i;
while (j < looplen)
{
num1 = num1 + marks[j];
j = j + rArrray+1;
}
list.Add(num1);
}

Hi Pruthvi,
use below code snippet for your output,
int[] arr = new int[] {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16};
int x = 1;
List resarr = new List();
int sum = 0;
for (int j = 0; j <= x; j++)
{
for (int i = j; i < arr.Length; i += x)
{
sum += arr[i];
i++;
}
resarr.Add(sum);
sum = 0;
}
