C program which deletes the duplicate element of an array
#include<stdio.h>
int main(){
int arr[50];
int *p;
int i,j,k,size,n;
printf("\nEnter size of the array: ");
scanf("%d",&n);
printf("\nEnter %d elements into the array: ",n);
for(i=0;i<n;i++)
scanf("%d",&arr[i]);
size=n;
p=arr;
for(i=0;i<size;i++){
for(j=0;j<size;j++){
if(i==j){
continue;
}
else if(*(p+i)==*(p+j)){
k=j;
size--;
while(k < size){
*(p+k)=*(p+k+1);
k++;
}
j=0;
}
}
}
printf("\nThe array after removing duplicates is: ");
for(i=0;i < size;i++){
printf(" %d",arr[i]);
}
return 0;
}
