long int mid;

int main()
{
long int n,i;
scanf("%ld",&n);
long int a[n];
for(i=0;i<n;i++)
scanf("%ld",&a[i]);
sort(a,a+n);
printf("%ld",find(a,n,0,n-1));
return 0;
}

main(){char *str;scanf("%s",str);printf("%s",str); }The error in the above program is: a) Variable 'str' is not initialised b) Format control for a string is not %s c) Parameter to scanf is passed by value. It should be an address d) none
