Question

Using an array and a function, print the values of an array backwards. Please follow these guidelines:

- Setup your array manually (whichever values you want, as many as you want and whichever datatype you prefer).

- Call your function. You should send two parameters to such function: the array’s length and the array.

- Inside the function, go ahead and print the array backwards.

- Your function shouldn’t return anything.

Answer 1

Solution:

Since no programmming language is specified I have provided the algorithm,pseudocode and a program in C++ language.

Algorithm for function:

START
   Step 1 → Loop for each value of A in reverse order 
   Step 2 → Display A[n] where n is the value of current iteration
STOP

Pseudocode of function:

procedure print_reverse(len,Array)

   FOR i from len-1 to 0
      DISPLAY A[i]
   END FOR
   
end procedure

C++ code of function:

void print_reverse(int len,int array[])
{
        int i=0;
        for(i = len-1; i >= 0; i--)
      cout<<array[i]<<" ";  
}

Complete implementation of code with main function:

#include <iostream>

using namespace std;

void print_reverse(int len,int array[])
{
        int i=0;
        for(i = len-1; i >= 0; i--)
      cout<<array[i]<<" ";  
}

int main() {
   int array[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0};
   int n=10;
   print_reverse(n,array);
   return 0;
}

Output of the above code:
