3 A – Write a Java program to read two integers a and b. Compute a/b and print, when b is not zero. Raise an exception when b is equal to zero.import java.util.Scanner;public class lab3a { lab3a() { int a,b; float c; Scanner sc=new Scanner(System.in); try { System.out.println(“Enter the value of a”); a=sc.nextInt(); System.out.println(“Enter the value ..

7. Implement using functions to check whether the given number is prime and display appropriate messages. (No built-in math function) ALGORITHM: Step 1: Start  Step 2: [Read the value of N(positive integers)]     Read N  Step 3: [to check whether N is prime or not] For i=2 to m/2  If m%i=0 then go to ..

12. Develop a program to find the square root of a given number N and execute for all possible inputs with appropriate messages. Note: Donâ€™t use library function sqrt(n).Algorithm: Step 1: start Step 2: read number Step 3: calculate number to the power of 0.5(sq=pow(n,0.5)) Step 4: print sq Step 5: stop FLOWCHART: PROGRAM:#include<stdio.h>#include<math.h> int ..

12. Write a program for congestion control using leaky bucket algorithm.Leaky.java – PROGRAMimport java.util.Scanner;public class Leaky { public static void main(String[] args)  { Scanner sc = new Scanner(System.in); int bcktsize, iter, rate, line, total = 0; int[] pkt = new int[25]; System.out.print(“Enter the bucket size and output rate(both in MB):”); bcktsize = sc.nextInt(); rate = sc.nextInt(); System.out.println(“Enter ..

9. Design, Develop and Implement a Program in C for the following operations on Singly Circular Linked List (SCLL) with header nodes a. Represent and Evaluate a Polynomial P(x,y,z) = 6x2y2z-4yz5+3x3yz+2xy5z-2xyz3 b. Find the sum of two polynomials POLY1(x,y,z) and POLY2(x,y,z) and store the result in POLYSUM(x,y,z) Support the program with appropriate functions for each of the above ..
