Answer 1

You can reverse an array in place you don't need an auxiliary array for that, Here is my C code to do that

#include 
int main(void)
 {
    int arr[5]={1,2,3,4,5};
    int size=sizeof(arr)/sizeof(int);   
    int success= reverse(arr,size);
    if(success==1)
        printf("Array reversed properly");
    else
        printf("Array reversing failed");   

    return 0;
}


int reverse(int arr[], int size)
{
    int temp=0;
    int i=0;
    if(size==0)
        return 0;
    if(size==1)
        return 1;

    int size1=size-1;
    for( i=0;i<(size/2);i++)
    {
        temp=arr[i];
        arr[i]=arr[size1-i];
        arr[size1-i]=temp;
    }

    printf("Numbers after reversal are ");
    for(i=0;i
