# Program to sort the elements of an array in descending order

Program to sort the elements of an array in descending order on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph etc.

## Q. Program to sort the elements of an array in descending order.

### Explanation

In this program, we need to sort the given array in descending order such that elements will be arranged from largest to smallest. This can be achieved through two loops. Outer loop will select a element and inner loop allow us to compare selected element with rest of the elements.

Original array:

Array after sorting:

Elements will be sort in such a way that largest element will appear on extreme left which in this case is 8. Smallest element will appear on extreme right which in this case is 1.

### Algorithm

1. Declare and initialize an array.
2. Loop through the array and select an element.
3. Inner loop will be used to compare selected element from outer loop with rest of the elements of array.
4. If any element is greater than the selected element then swap the values.
5. Continue this process till entire list is sorted in descending order.

### Python

```#Initialize array
arr = [5, 2, 8, 7, 1];
temp = 0;

#Displaying elements of original array
print("Elements of original array: ");
for i in range(0, len(arr)):
print(arr[i]),

#Sort the array in descending order
for i in range(0, len(arr)):
for j in range(i+1, len(arr)):
if(arr[i] < arr[j]):
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;

print();

#Displaying elements of array after sorting
print("Elements of array sorted in descending order: ");
for i in range(0, len(arr)):
print(arr[i]),
```

Output:

```Elements of original array:
5 2 8 7 1
Elements of array sorted in descending order:
8 7 5 2 1
```

### C

```#include
int main()
{
//Initialize array
int arr[] = {5, 2, 8, 7, 1};
int temp = 0;

//Calculate length of array arr
int length = sizeof(arr)/sizeof(arr[0]);

//Displaying elements of original array
printf("Elements of original array: \n");
for (int i = 0; i < length; i++) {
printf("%d ", arr[i]);
}

//Sort the array in descending order
for (int i = 0; i < length; i++) {
for (int j = i+1; j < length; j++) {
if(arr[i] < arr[j]) {
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}
printf("\n");
//Displaying elements of array after sorting
printf("Elements of array sorted in descending order: \n");
for (int i = 0; i < length; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```

Output:

```Elements of original array:
5 2 8 7 1
Elements of array sorted in descending order:
8 7 5 2 1
```

### JAVA

```public class SortDsc {
public static void main(String[] args) {
//Initialize array
int [] arr = new int [] {5, 2, 8, 7, 1};
int temp = 0;

//Displaying elements of original array
System.out.println("Elements of original array: ");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + " ");
}

//Sort the array in descending order
for (int i = 0; i < arr.length; i++) {
for (int j = i+1; j < arr.length; j++) {
if(arr[i] < arr[j]) {
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}

System.out.println();

//Displaying elements of array after sorting
System.out.println("Elements of array sorted in descending order: ");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + " ");
}
}
}
```

Output:

```Elements of original array:
5 2 8 7 1
Elements of array sorted in descending order:
8 7 5 2 1
```

### C#

```using System;

public class SortDsc
{
public static void Main()
{
//Initialize array
int [] arr = new int [] {5, 2, 8, 7, 1};
int temp = 0;

//Displaying elements of original array
Console.WriteLine("Elements of original array: ");
for (int i = 0; i < arr.Length; i++) {
Console.Write(arr[i] + " ");
}

//Sort the array in descending order
for (int i = 0; i < arr.Length; i++) {
for (int j = i+1; j < arr.Length; j++) {
if(arr[i] < arr[j]) {
temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
}
}

Console.WriteLine();

//Displaying elements of array after sorting
Console.WriteLine("Elements of array sorted in descending order: ");
for (int i = 0; i < arr.Length; i++) {
Console.Write(arr[i] + " ");
}
}
}
```

Output:

```Elements of original array:
5 2 8 7 1
Elements of array sorted in descending order:
8 7 5 2 1
```

### PHP

```<!DOCTYPE html>
<html>
<body>
<?php
//Initialize array
\$arr = array(5, 2, 8, 7, 1);
\$temp = 0;

//Displaying elements of original array
print("Elements of original array: <br>");
for (\$i = 0; \$i < count(\$arr); \$i++) {
print(\$arr[\$i] . " ");
}

//Sort the array in descending order
for (\$i = 0; \$i < count(\$arr); \$i++) {
for (\$j = \$i+1; \$j < count(\$arr); \$j++) {
if(\$arr[\$i] < \$arr[\$j]) {
\$temp = \$arr[\$i];
\$arr[\$i] = \$arr[\$j];
\$arr[\$j] = \$temp;
}
}
}

print("<br>");

//Displaying elements of array after sorting
print("Elements of array sorted in descending order: <br>");
for (\$i = 0; \$i < count(\$arr); \$i++) {
print(\$arr[\$i] . " ");
}
?>
</body>
</html>
```

Output:

```Elements of original array:
5 2 8 7 1
Elements of array sorted in descending order:
8 7 5 2 1
```
