Program for Left Rotation of Array in C++

In this example, you learn about the c ++ program for the left rotation of an array.

Here you learn Program for the left turn of an array in C ++, this problem you see in competitive programming sites like leetcode, hackerrank etc. You have an array and then rotate the array clockwise.


A left turn of an array or an array rotation in one in the left direction are both identical. By doing this, we first store the first element of an array in a temporary space and then move the array components one by one on the left side of the array and at the end we will replace the last element of the array with a temporary element.

using namespace std;  
int main()  
    int arr[] = 11, 22, 33, 44, 55; //Initialization array   
    int len = sizeof(arr)/sizeof(arr[0]);  //Calculate length of array arr 
    cout<<"Array Before Left Rotation: n"; //Displays Array  
    for (int i = 0; i < len; i++)    
    int j, temp;  
    temp = arr[0]; //Stores the first element of the array into temporary space   
    for(j = 0; j < len-1; j++)  
      arr[j] = arr[j+1];   //Shift element of array by one  
    arr[j] = temp;  //Now Set temporary element of array to the end  
    cout<<"Array After Left Rotation: n";  //Displays Resulting Array 
    for(int i = 0; i < len; i++)  
	return 0;  


Array Before Left Rotation:
11      22      33      44      55
Array After Left Rotation:
22      33      44      55      11
