Please, post the declaration of your array and explain what your function void fun() is supposed to do.

#include <iostream>
#include <time.h>
#include <stdlib.h>
using namespace std;
void func(int x[0])//my doubt is here
{
    cout<<x[2]<<x[3];


}
int main()
{

    int a[4]={1,2,3,5};
    func(a);
	return 0;
}

in void func i have declared size of array x has 0.but it displaying value of x[2],x[3].how is this

Well, your doubt is correct. BTW, does it compile?
the correct way to declare this function would be

void func(int x[])

or

void func(int* x)

Besides, if this function does not modify the array then declare it as

void func(const int* x)

Sorry, I dont understand what it means.
Note that you go not pass the "entire array elements" but only the pointer to the first array element (with the index zero).
And the function should care to not access something outside the array bounds. To provide it you should also pass the array size as additional parameter and let your function check whether the index of accessed array elements is between zero and its upper bound.

It is because you already rated me today. You cannot rate the same person again unless you have not rated someone else before...
