Question

Randomly generate an integer number in range [1, 999], (a) Check if this number is even or odd, display message “[number] is an even number” or “[number] is an odd number”. For example, if the number is 10, display message “10 is an even number”. (b) Check if this number is divisible by 7 and 11. Display message showing result (c) Check if this number is divisible by 9 or 13. Display message showing result (d) Check if this number is divisible by 5 or 12, but not both. Display result

Required program in JAVA -->

import java.util.Random;

public class Main{

public static void main(String args[])

{

Random rand = new Random();

int number = rand.nextInt(1000);
//randomly generate a value between 0 to 1000

System.out.println("Random Number:
"+number); // show the randomly generated number

if(number%2==0){ // if number%2==0
means if number is even

System.out.println(number+" is even
number"); // print number is even

}

else{ // number is odd

System.out.println(number+" is odd
number"); //print number is odd

}

if(number%7==0 &&
number%11==0){ //if number is divisible by 7 and 11

System.out.println("Number is
divisible by 7 and(&&) 11"); //print divisible

}

else{ // if number is not divisible
by 7 and 11

System.out.println("Number is not
divisible by 7 and(&&) 11"); //print not divisible

}

if(number%9==0 || number%13==0){
//if number is divisible by 9 or 13

System.out.println("Number is
divisible by 9 or(||) 13"); //print divisible

}

else{ //if number is not divisible
by 9 or 13

System.out.println("Number is not
divisible by 9 or(||) 13"); //print not divisible

}

if(number%5==0 || number%12==0){
//if number is divisible by 5 or 12

System.out.println("Number is
divisible by 5 or(||) 12"); //print divisible

}

else{ // if number is not divisible
by 5 or 12

System.out.println("Number is not
divisible by 5 or(||) 12"); //print not divisible

}

}

Randomly generate an integer number in range [10, 99]. Write a
program to check if the digit at 10’s position is less than the
digit at 0’s position. If yes, swap these 2 digits. Display
original number and new number. For example, if the number
generated is 53, after process, the new number will be 35. If
original number is 12, no process needed. If the number is 50, the
new number will be 5.

In Java : Randomly generate an integer number in range [10, 99].
Write a program to check if
the digit at 10’s position is less than the digit at 0’s position.
If yes, swap these 2
digits. Display original number and new number. For example, if the
number
generated is 53, after process, the new number will be 35. If
original number is 12,
no process needed. If the number is 50, the new number will be
5.

Write a program that prompts
the user to enter an integer number between 1 and 999. The program
displays the sum of all digits in the integer if the input is
valid; otherwise, it displays a message indicating that the integer
is not between 1 and 999 and hence, is invalid.
Name the program file Q1.cpp
Example: if the user enters 12, sum of digits is
3.
If the user enters 122, sum of digits is 5.

A prime number is an integer greater than 1 that is evenly
divisible by only 1 and itself. For example, 2, 3, 5, and 7 are
prime numbers, but 4, 6, 8, and 9 are not. Create a PrimeNumber
application that prompts the user for a number and then displays a
message indicating whether the number is prime or not. Hint: The %
operator can be used to determine if one number is evenly divisible
by another. ( Java programing...

Write program to generate random numbers in different range and
display: (c) A number in range [0, 10) (d) A number in range [0,
1000] (e) A number in range [-99, 99] (f) A double number in range
[1000.0, 9999.0)

8. It is possible to check if an integer is divisible by 9 by
summing its digits: if the digits add up to 9 the number is
divisible by 9. For integers up to 90 only a single application of
the rule is required. For larger integers, multiple applications
may be required. For example, for 99, the digit sum is 18. Then,
because 18 still has multiple digits we sum them again to get 9,
confirming that 99 is divisible...

Write a java program to display a given range of integer numbers
(0 to 9) in the following order:
Example : given (5 to 9), the program displays
56789
67895
78956
89567
95678
The first line displays the min to max range. Each line that
follows should display the next higher number except when it hits
the maximum number. In that situation, the line wraps back to the
minimum sequence. For this problem write a static
method to do the...

a.
An integer is a "Lucky Number" if it is divisible by 7 or is
divisible by 11 and it is in the range 1000 through 4000.
Write a Boolean expression that is true if and only if myNum (an
int variable) contains a Lucky Number.
b.
Let a and b represent the length and the width of a
rectangle.
The length of the diagonal of the rectangle can be calculated by
the following mathematical expression.
diagonalLength = squareRoot(a...

IN C++ AS SIMPLE AS POSSIBLE ______
Re-write the given function,
printSeriesSquareFifth, to
use a while loop (instead of for).
• The function takes a single integer n as a
parameter
• The function prints a series between 1 and
that parameter, and also prints its result
• The result is calculated by summing the numbers between 1 and
n (inclusive). If a number is divisible by 5, its
square gets added to the result instead.
• The function does not...

5 numbers chosen randomly without replacement. (#'s range 1-39).
"B" represents number of even numbers, this random variable has
this probability:
x

5
p(B=x)
0.02693
0.15989
.33858
.31977

number of odd #s chosen would then be 5-x, if x is even #s
chosen. "C" represents difference b/w # of even and # of odd
chosen, --> C= 2B-5
