how to sort structures in c 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: sorting array in c

#include <stdio.h>
    void main()
    {
 
        int i, j, a, n, number[30];
        printf("Enter the value of N \n");
        scanf("%d", &n);
 
        printf("Enter the numbers \n");
        for (i = 0; i < n; ++i)
            scanf("%d", &number[i]);
 
        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 ascending order are given below \n");
        for (i = 0; i < n; ++i)
            printf("%d\n", number[i]);
 }
