Implement Selection sort in Java.

-
*Selection Sort:
           
        The selection sort is a combination of searching and sorting. During each pass, the unsorted element with the smallest (or largest) value is moved to its proper position in the array. The number of times the sort passes through the array is one less than the number of items in the array. In the selection sort, the inner loop finds the next smallest (or largest) value and the outer loop places that value into its proper location.
Selection Sort

//Write a Java program for implementing Selection Sort.

public class MySelectionSort {
    public static int[] doSelectionSort(int[] arr){
         
        for (int i = 0; i < arr.length - 1; i++)
        {
            int index = i;
            for (int j = i + 1; j < arr.length; j++)
                if (arr[j] < arr[index])
                    index = j;
      
            int smallerNumber = arr[index]; 
            arr[index] = arr[i];
            arr[i] = smallerNumber;
        }
        return arr;
    }
     
    public static void main(String a[]){
         
        int[] arr1 = {10,34,2,56,7,67,88,42};
        int[] arr2 = doSelectionSort(arr1);
        for(int i:arr2){
            System.out.print(i);
            System.out.print(", ");
        }
    }
}

//A small example to show how to use execvp() function in C. We will have two .C files , EXEC.c and execDemo.c and we will replace the execDemo.c with EXEC.c by calling execvp() function in execDemo.c . //EXEC.c  #include<stdio.h>  #include<unistd.h>  int main()   {        int i;       printf("This  is EXEC.c, called by execvp() ");        printf("\n");       return 0;   }  Now,create an executable file of EXEC.c using command  gcc EXEC.c -o EXEC //execDemo.c #include<stdio.h> #include<stdlib.h>  #include<unistd.h>  int main()  {     //A null terminated array of character      //pointers       char *args[]={"./EXEC",NULL};       execvp(args[0],args);     /*All statements are ignored after execvp() call as this whole process(execDemo.c) is replaced by ...

Implement a class CppArray which is identical to a one-dimensional C++ array (i.e., the index set is a set of consecutive integers starting at 0) except for the following : 1. It performs range checking. 2.It allows one to be assigned to another array through the use of assignment operator. 3.It supports a function that returns the size of the array.
