single error detection using parity bit in c program

#include<stdio.h>

void main()
{
    int data[5], parity_bit,n,i,count=0;
    printf("Number of Data Bit: ");
    scanf("%d",&n);
    for(i=0; i<n; i++)
    {
        printf("Enter number %d: ", i+1);
        scanf("%d",& data[i]);
    };
    printf("Enter the parity bit: ");
    scanf("%d",&parity_bit);

    data[n]=parity_bit;
    printf("Code Word: ");
    for(i=0; i<=n; i++)
    {
        printf("%d ", data[i]);
    };
    printf("\n");

    for(i=0; i<=n; i++)
    {
        if (data[i]==1)
        {
            count++;
        }
    };
    printf("Number of 1 in Data Bit: %d \n",count);

    if(count%2==0)
    {
        printf("Result: No Error!");
    }
    else
    {
        printf("Result: Error!");
    }
