#include<stdio.h> #include<conio.h> main() { int a[20],i,j,k,n; clrscr(); printf("nEnter array size : "); scanf("%d",&n); printf("nAccept Numbers : ",n); for(i=0;i<n;i++) scanf("%d",&a[i]); clrscr(); printf("nOriginal array is : "); for(i=0;i<n;i++) printf(" %d",a[i]); printf("nUpdated array is : "); for(i=0;i<n;i++) { for(j=i+1;j<n;) { if(a[j]==a[i]) { for(k=j;k<n;k++) a[k]=a[k+1]; n--; } else j++; } } for(i=0;i<n;i++) printf("%d ",a[i]); getch(); }
