Find Middle Number in C

#include<stdio.h>
int main(){
int n;
printf("How many number to find: ");
scanf("%d", &n);
int i, a[n];
for(i=0;i<=(n-1);i++)
    scanf("%d", &a[i]);

    int b[n/2],c[n/2];
    for(i=0;i<=(n/2-1);i++)
        b[i]=a[i];
        printf("\n%d Is Middle Number",a[i]);

        c[j]=a[i];
        j++;}

    printf("\n%d Is Middle Index",j);
