Program in C
Here is the source code of the C Program to Remove duplicate elements in an array.
Code:
#include<stdio.h>
int sort_arr(int arr[],int size)
{
int i,j,temp;
//Sort the array
for(i=0;i<size;i++)
{
for(j=i+1;j<size;j++)
if(arr[i]>arr[j])
{
temp=arr[i];
arr[i]=arr[j];
arr[j]=temp;
}}
}
main()
{
printf("Enter the size of the array:");
int size,i,j=0;
scanf("%d",&size);
int arr[size];
printf("Enter the Element of the array:\n");
for(i=0;i<size;i++)
{
scanf("%d",&arr[i]);
}
sort_arr(arr,size);
//Remove duplicate element
for(i=0;i<size-1;i++)
{
if(arr[i]!=arr[i+1])
{
arr[j++]=arr[i];
}
}
arr[j++]=arr[size-1];
printf("After removing duplicate element array is ");
for(i=0;i<j;i++)
printf("%d ",arr[i]);
}
int sort_arr(int arr[],int size)
{
int i,j,temp;
//Sort the array
for(i=0;i<size;i++)
{
for(j=i+1;j<size;j++)
if(arr[i]>arr[j])
{
temp=arr[i];
arr[i]=arr[j];
arr[j]=temp;
}}
}
main()
{
printf("Enter the size of the array:");
int size,i,j=0;
scanf("%d",&size);
int arr[size];
printf("Enter the Element of the array:\n");
for(i=0;i<size;i++)
{
scanf("%d",&arr[i]);
}
sort_arr(arr,size);
//Remove duplicate element
for(i=0;i<size-1;i++)
{
if(arr[i]!=arr[i+1])

arr[j++]=arr[i];
}
}
arr[j++]=arr[size-1];
printf("After removing duplicate element array is ");
for(i=0;i<j;i++)
