how can i fix it the oppisite way?

#include <stdio.h>
#define N 5
void main() 
{
			   
	int a[N];
	int index[N];
	int i,j,temp;
	int count=0;

	for(i=0; i<N; i++)
		{	//set the values of array a[]
			scanf("%d",&a[i]);
			//initializing the index[] array from 0->N-1
			index[i]=count++;

	for(i=0; i<N; i++)

for (i = 0; i < N; ++i)
{
	printf("%d ",index[i]);

flushall();
getchar();
