Here there is segmentation fault here, why?

What I have tried:

C++
#include<stdio.h>
int findmid(int [],int);
int main()
{
    int n,c,i;
    int a[n];
    printf("Enter the valu of n :");
    scanf("%d",&n);
    int x;
    for(i=0;i<n;i++)
    scanf("%d",&a[i]);
    x=sizeof(a)/sizeof(int);
    c=findmid(a,x);
    printf("%d",c);
    return 0;
}

int findmid(int a[],int x)
{
    return a[x/2];
}

Because your code is wrong
C++
#include<stdio.h>
int findmid(int [],int);
int main()
{
    int n,c,i;
    int a[n]; // you can't allocate an array dynamically sized at runtime
    printf("Enter the valu of n :");
    scanf("%d",&n); // before knowing the size
    int x;
    for(i=0;i<n;i++)
    scanf("%d",&a[i]);
    x=sizeof(a)/sizeof(int);
    c=findmid(a,x);
    printf("%d",c);
    return 0;
}

int findmid(int a[],int x)
{
    return a[x/2];
}
