# C++ Program to Split the array and add the first part to the end?

Server Side ProgrammingProgrammingC++

Here we will see how to split an array, and add the first part after splitting at the end position. Suppose the array contents are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. We want to cut this intro two parts. The first part is from index 0 to 3 (split size 4), and second part is rest. After adding the first part at the end, the array elements will be like this {4, 5, 6, 7, 8, 9, 0, 1, 2, 3}. To solve this problem, we will follow this algorithm.

## Algorithm

#### splitArray(arr, n, k)

begin
for i := 0 to k, do
x := arr
for j := 0 to n-2, do
arr[j] := arr[j+1]
done
arr[n-1] := x
done
end

## Example

Live Demo

#include<iostream>
using namespace std;
void splitArray(int arr[], int n, int k){
for(int i = 0; i<k; i++){
int x = arr; //take the first number
for(int j = 0; j<= n-2; j++){
arr[j] = arr[j+1];
}
arr[n-1] = x;
}
}
main() {
int data[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
int n = sizeof(data)/sizeof(data);
int i;
cout << "Enter split size: ";
cin >> i;
splitArray(data, n, i);
for(int i = 0; i <n;i++){
cout << data[i] << " ";
}
}

## Output

Enter split size: 4
4 5 6 7 8 9 0 1 2 3
