I want to write a program which allows a user to enter the values of an array using a for loop, however I am getting an error which says "name lookup of x changed for ISO 'for' scoping"
i am new to C++ (two weeks) and i have NO clue what this means. here is my code

code:


#include <iostream>

using namespace std;

int array[3];

int main()
{
    for (int x = 0 ; x <=2 ; x++)
    cout <<"Enter an integer ==> ";
    cin >> array[x];

}


thanks in advance for any help[syntax=""][/syntax][syntax=""][/syntax]

The problem is that for line
code:

cin >> array[x];

variable x does not exist (it was never declared in the current scope).
