C program to remove even numbers and fill it with zero Input array 1,2,3,4,5,6 Output 1,3,5,0,0,0 #include<stdio.h> void main() int i,j,k,n=6,a[]={1,2,3,4,5,6}; clrscr(); for(i=0;i<n;i++) { if(a[i]%2==0) { a[i]=-1; } else printf("%d",a[i]); } for(i=0;i<n;i++) { if(a[i]==-1) printf("0"); } getch(); }

actually first ++a is incrementing two times and during first increment it is asigned to 6 during second 7 and now the values is 7 for both a therefore the op is 7+7
