bubble sort descending order in c code example

Example 1: bubble sort c

#include <bits/stdc++.h> 
using namespace std; 
  
void swap(int *xp, int *yp)  
{  
    int temp = *xp;  
    *xp = *yp;  
    *yp = temp;  
}  
  
// A function to implement bubble sort  
void bubbleSort(int arr[], int n)  
{  
    int i, j;  
    for (i = 0; i < n-1; i++)      
      
    // Last i elements are already in place  
    for (j = 0; j < n-i-1; j++)  
        if (arr[j] > arr[j+1])  
            swap(&arr[j], &arr[j+1]);  
}  
  
/* Function to print an array */
void printArray(int arr[], int size)  
{  
    int i;  
    for (i = 0; i < size; i++)  
        cout << arr[i] << " ";  
    cout << endl;  
}  
  
// Driver code  
int main()  
{  
    int arr[] = {64, 34, 25, 12, 22, 11, 90};  
    int n = sizeof(arr)/sizeof(arr[0]);  
    bubbleSort(arr, n);  
    cout<<"Sorted array: \n";  
    printArray(arr, n);  
    return 0;  
}

Example 2: how to sort an array in c'=

for (i = 0; i < n; ++i) 
        {
 
            for (j = i + 1; j < n; ++j)
            {
 
                if (number[i] > number[j]) 
                {
 
                    a =  number[i];
                    number[i] = number[j];
                    number[j] = a;
 
                }
 
            }

Example 3: c program to arrange numbers in descending order

/* C program to arrange numbers in descending order DescOrder.C */

#include <stdio.h>
 
void main ()
{
 //variable declaration
 int number[30];
 int i, j, a, n;

 //asking user to enter size of array 
 printf("Enter the value of N\n");
 scanf("%d", &n); //reading array size
 
 //asking user to enter array elements
 printf("Enter the numbers \n"); 
 for (i = 0; i < n; ++i)
  scanf("%d", &number[i]); //reading array elements

 /* Logic for sorting and checking */

 for (i = 0; i < n; ++i)
 {
   for (j = i + 1; j < n; ++j)
   {
    if (number[i] < number[j])
    {
     a = number[i];
     number[i] = number[j];
     number[j] = a;
   }
  }
 }
 
 printf("The numbers arranged in descending order are given below\n");
 for (i = 0; i < n; ++i)
 {
   printf("%d\n", number[i]); //printing numbers in descending order
 }
}
