selection sort 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;

selection sort in java

public static void SelectionSort(int[] arr)
{
  int small;
  for (int i = 0; i <arr.length - 1; i++)
  {
    small = i;
    for (int j = i + 1; j < arr.length; j++)
    {
      //if current position is less than previous smallest
      if (arr[j] < arr[small])
      {
        small = j;
        
        //swap values
        int temp = arr[i];
        arr[i] = arr[small];
        arr[small] = temp; 
      }
  	}
  }

    return lst
if __name__=='__main__':
    lst=[int(i) for i in input('Enter the Numbers: ').split()]
    print(ssort(lst))

how to send values to a selection sorting function

1  // Fig. 8.15: fig08_15.cpp
 2  // This program puts values into an array, sorts the values into
 3  // ascending order and prints the resulting array.
 4  #include <iostream>

 8  #include <iomanip>
 9  using std::setw;
10
11  void selectionSort( int * const, const int ); // prototype

20
21     for ( int i = 0; i < arraySize; i++ )
