I want to shift the elements of a 2D array by n-elements to the right. My array has 26 Elements.
This doens't seem to work, and I don't know why.

i = 2;

c = 0;

for (i; i < 26; i++)

{

  array[1][i-1] = array[1][c];

  c++;

}

But I am overwriting every Element at Index i with the element of the array[0][0] and not with the next elemetn.

The indexvariable c doesn't seem to increment and I don't really know why.

Thankfull for any input.

Take a piece of paper and write down what happens step by step.

Like:

i = 2;

c = 0;

array[1][1] = array[1][0];

c=1;

i=3;

array[1][2] = array[1][1];

c=2;

i=4;

array[1][3] = array[1][2];

. . .

As you can see you start by assigning value of element 0 to element 1, then you assign value of element 1 to element 2. Since the value of element 1 is the same as value of element 0, element 2 now holds the same value as element 0 and element 1. So in the end, you actually assigns the value of element 0 to all other elements.

The solution is to start from the other end. That is:

array[1][25] = array[1][24];

array[1][24] = array[1][23];

array[1][23] = array[1][22];
