C program to right rotate an array; Through this tutorial, we will learn how to right rotate an array using standard method and function in c programs.
Programs to Right Rotate Array Elements in C
Checkout the following program to right rotate an array using standard method and function in c:
- C Program to Right Rotate Array Elements using Standard Method
- C Program to Right Rotate Array Elements using Function
C Program to Right Rotate Array Elements using Standard Method
#include <stdio.h>
int main()
{
int a[10000],i,n,j,k,temp;
printf("Enter size of the array : ");
scanf("%d", &n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d",&a[i]);
}
printf("how many times right rotate : ");
scanf("%d", &k);
for(i=0; i<k; i++)
{
temp=a[n-1];
for(j=n-1; j>0; j--)
{
a[j]=a[j-1];
}
a[j]=temp;
}
printf("\narray elements after right rotate : ");
for(i=0; i<n; i++)
{
printf("%d ",a[i]);
}
}
The output of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 1 2 3 4 5 how many times right rotate : 2 array elements after right rotate : 4 5 1 2 3
C Program to Right Rotate Array Elements using Function
#include <stdio.h>
int rightrotate(int *a,int n,int k)
{
int i,j,temp;
for(i=0; i<k; i++)
{
temp=a[n-1];
for(j=n-1; j>0; j--)
{
a[j]=a[j-1];
}
a[j]=temp;
}
}
print(int *a,int n)
{
int i;
for(i=0; i<n; i++)
{
printf("%d ",a[i]);
}
}
int main()
{
int a[10000],i,n,j,k,temp;
printf("Enter size of the array : ");
scanf("%d", &n);
printf("Enter elements in array : ");
for(i=0; i<n; i++)
{
scanf("%d",&a[i]);
}
printf("how many times right rotate : ");
scanf("%d", &k);
rightrotate(a,n,k);
printf("\narray elements after right rotate : ");
print(a,n);
}
The output of the above c program; as follows:
Enter size of the array : 5 Enter elements in array : 1 2 3 4 5 how many times right rotate : 4 array elements after right rotate : 2 3 4 5 1
