c program ascending order code example

Example 1: sorting program in c

#include<stdio.h>
int main(){
   /* Here i & j for loop counters, temp for swapping,
    * count for total number of elements, number[] to
    * store the input numbers in array. You can increase
    * or decrease the size of number array as per requirement
    */
   int i, j, count, temp, number[25];

   printf("How many numbers u are going to enter?: ");
   scanf("%d",&count);

   printf("Enter %d elements: ", count);
   // Loop to get the elements stored in array
   for(i=0;i<count;i++)
      scanf("%d",&number[i]);
 
   // Logic of selection sort algorithm
   for(i=0;i<count;i++){
      for(j=i+1;j<count;j++){
         if(number[i]>number[j]){
            temp=number[i];
            number[i]=number[j];
            number[j]=temp;
         }
      }
   }

   printf("Sorted elements: ");
   for(i=0;i<count;i++)
      printf(" %d",number[i]);

   return 0;
}

Example 2: 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
 }
}
