Answer:
JAVA
TASK 1
float float75 = 75; # widening casting are done automatically.
String string75 = String.valueOf(75);
float75 + string75 = Error: As the compiler doesn't know how to approach this, are you trying to add float to unicode charcters, if there is a value in this string, CAST it out, EXORCISE
TASK 2
import java.util.Scanner;
class MyClass {
public static void main(String[] args) {
Scanner myObj = new Scanner(System.in); // Create a Scanner object
System.out.println("Enter Float number");
float number = myObj.nextFloat();
System.out.println(number ** 2);
TASK 3
import java.util.Scanner;
class MyClass {
public static void main(String[] args) {
Scanner myObj = new Scanner(System.in); // Create a Scanner object
System.out.println("Enter number");
int number = myObj.nextInt();
int quotient = number / 7;
int reminder = number % 7;
System.out.printf("When you divide %d by 7, the quotient is %d and the reminder is %d ", number, quotient, reminder);
TASK 4
import java.util.Scanner;
class MyClass {
public static void main(String[] args) {
Scanner myObj = new Scanner(System.in); // Create a Scanner object
System.out.println("How many gigabytes is your flash drive");
int gigabytes = myObj.nextInt();
long numBits = gigabytes * 8000000000
System.out.printf("Number of bits in your %d flashdrive: %ld Bits", gigabytes, numBits);
