Filling an array backwards using for loop

Question

I want to fill an array from the highest index and descending order. A sample code as shown:
#include <iostream>
using namespace std;
int main()
{
int myArr[5];
for(int x=4; x<1; x--) {
myArr[x] = x;
cout << x << ": " << myArr[x] << endl;
}
return 0;
}
Running the code shows no output, can someone explain why it doesn't work?

Answer 1

use for loop as
for(int x=4; x>=0; x--)
myArr[x] = x;

Answer 2

Ok, my condition in the for loop was wrong, that's why it's not running. Thanks boss
