How to sort simple array in c++

Some times we need to sort out arrays in programs to find out precise results.Sorting an array is an easy process.Just declare an array.Declare four local variables that will help us in iteration and sorting.Now display a single message to user and ask for output.

In next line write a scanf function that will take input value from the user.The user will have to enter five values.Once all values has been entered successfully.

In next step a loop will find minimum number in array and then sort in out in ascending way.Once array is sorted.Then it will be displayed to the user.That's it.

But always remember one thing there is no check points.For example if user enters a character instead of integer, then program may get crashed.

#include <iostream>

#include <conio.h>

using namespace std;

int main()

{

    int a[16], i, j, k, temp;

    cout<<"enter the elements\n";

    for (i = 0; i < 5; i++)

    {

        cin>>a[i];

    }

    for (int i =5; i >= 0; i--)
   {
      for (int j = 1; j<= i; j++)
      {
         if (a[j-1] > a[j])
         {
              int temp = a[j-1];
              a[j-1] = a[j];
              a[j] = temp;
   } } } 

    cout<<"sorted array\n"<<endl;

    for (k = 0; k < 5; k++)

    {

 cout<<a[k]<<endl;

    }

    getch();}
