Cpp Tutorial to reverse an array code

Write a program which takes some elements as input in integer array then pass this array to a function which reverse its elements using for loop and swapping. 
 Display the reversed array with index number. Loop should execute less than array size. Use any c compiler (codeBlocks recommended).

This tutorial contains the following concepts

Program explanation
  • Program declare an integer array of size five, initialize it using for loop
  • Pass size and array name to function 
  • Function uses for loop and swap array elements with in it
  • A for loop is used to display the final result

Compiler used: CodeBlocks C Compiler
  1. #include <iostream>
  2. using namespace std;
  3. void Reverse_Array(int array[],int size)
  4. {   int temp;
  5.     size--;
  6.     int loop_count=0;
  7.     for(int i=0;size>=i;size--,i++)
  8.     {
  9.         loop_count++;// Counts the iterations
  10.         temp=array[i];
  11.         array[i]=array[size];
  12.         array[size]=temp;
  13.     }
  14.     cout<<"Number of Iterations: "<<loop_count<<endl;
  15. }
  16. int main()
  17. {
  18.     int array[5],i;
  19.     cout<<"\nEnter 5 Integer Values in Array\n"<<endl;
  20.     for(i=0;i<5;i++)
  21.     {
  22.     cout<<"Enter Value For Index Number array [ "<<i<<" ] -> ";
  23.     cin>>array[i];
  24.     }
  25.     // Calling Reverse Array Values Function
  26.     Reverse_Array(array,5);
  27.     cout << "\n\n\t\t\tReversed Array Values" << endl;
  28.     for(i=0;i<=4;i++)
  29.         {
  30.          cout<<"\t\t\tarray ["<<i<<"]"<<"= "<<array[i]<<endl;
  31.         }
  32.     return 0;
  33. }
