8085 Program to perform sorting using selection sort
Now let us see a program of Intel 8085 Microprocessor. In this program we will see how to sort a sequence of numbers using selection sort.Problem Statement:Write 8085 Assembly language program to sort a given sequence using selection sort in ascending order. The numbers are stored at 8001H onwards. 8000H is holding the block size.Discussion:In the selection sorting technique, we will choose the minimum or the maximum term from a set of numbers. In this case we are considering the sorting in ascending order, so we are choosing the minimum number. By taking the minimum number, we are swapping it ...

Read MoreJava Program to generate random elements from a given array
Let’s say the following is our array −Integer[] arr = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20};Now, we can convert it to a list before shuffling it −Listlist = Arrays.asList(arr); Collections.shuffle(list);The above shuffling generates random elements. Display them like this −for (Integer res: list) { System.out.print(res + " "); }Example Live Demoimport java.util.Arrays; import java.util.Collections; import java.util.List; public class Demo { public static void main(String[] args) { Integer[] arr = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}; System.out.print("Array elements..."); for (Integer res: arr) { ...
Read MoreAssigning multiple characters in an int in C language
The character type data is stored by its ASCII value internally in C or C++. If we want to print a single character as integer, we will get the ASCII value. But when we are trying to print more than one character using a single quote, then it will print some strange output.Please check the following program to get the idea.Example#include int main() { printf("%d", 'A'); printf("%d", 'AA'); printf("%d", 'ABC'); }Output65 16705 4276803The ASCII of A is 65. So at first it is showing 65 (01000001). Now for AA, it is showing 16705. This is ASCII ...
