Remove duplicates. What's wrong with my code?

Question

#include <stdio.h>

int main() {
int n= 0;
int count= 0;
scanf("%d", &n);
int arr[100];
int dupl=0;
for(int i=0; i<n; i++) scanf("%d", &arr[i]);
for(int i=0; i<n; i++){
for(int j=0; j<=i; j++){
dupl= arr[i]==arr[j] && i!=j;
if(dupl==1){
count++;
for(int k=i; k<n; k++){
arr[k]= arr[k+1];
}
}
}
}
for(int i=0; i<n-count; i++){
printf("%d ", arr[i]);
}
printf("\ncount of dupl.= %d& new array size= %d", count, n-count);
return 0;
}

Answer 1

What problem you getting with this..?
Edit: Jaan
OK. For some test cases, it failing.
Just change in line 10,
n to n-count in loop like

for(int i=0; i<n-count; i++){
..
}

Thank you Jayakrishna🇮🇳
Great Learning!! Updating the array size in case of deletion/ insertion is important in iterations especially 🙋
Thank you

loop from end
