    Here is my solution to this without using pointers:

    int main() {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */ 
    int size;
    cin >> size;
    int nums[size];
    for (int i = size - 1; i >= 0; i--) {
        cin >> nums[i];
    }
    for (int j = 0; j < size; j++){
        cout << nums[j] << " ";
    }
    
     
    return 0;
}

    include iostream

    int main() { int n; std::cin>>n; const int SIZE = n; int numbers[SIZE]; 

    for (int i = 0; i < n; ++i) {
    std::cin >> numbers[i]; 
}
for (int i=0; i<n/2 ; ++i){
    int temp =numbers[i];
    numbers[i]=numbers[n-1-i];
    numbers[n-1-i]=temp;
}
for(int i= 0; i< n; ++i){
    std::cout<<numbers[i]<<" ";
}


return 0;
