Answer:

Explanation:

Each of the following println statements will print the following values

ystem.out.println(floozy); // Problem 1: 97.4

System.out.println(theObj.gravy); //Problem 2: 107.43

System.out.println(xray[2]); //Problem 3: 100

System.out.println(s); //Problem 4: Hello

This is because out of all of the variables that the myMethod gives a value to, the only variable that is being saved back to the global variable in the main method is a[2]. The other variables are being saved as instance variables and not being returned. Therefore, when the println statements are called they target the local variables in the main method.

Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and s

S_A_V [24]

Answer:

// program in C++.

#include <bits/stdc++.h>

using namespace std;

int main() {

// variable

int num;

cout<<"Enter the number between 20 and 98: ";

// read number

cin >> num;

while(num<20||num>98)

{

cout<<"Wrong input!!enter number between 20-98 only:";

cin>>num;

}

cout<<"The output is: ";

while(num % 10 != num /10)

{

// print numbers.

cout<<num<<" ";

// update num.

num--;

}

// display the number.

cout<<num<<endl;;

return 0;

}

Explanation:

Read a number from user and assign it to variable "num".Check if entered number is in between 20-98 or not.If input number is less than 20 or greater than 98 then ask again to enter a number between 20-98 until user enter a valid input.Then print the countdown from input number till both the digit of number are same.

Output:

Enter the number between 20 and 98: 99

Wrong input!!enter number between 20-98 only:12

Wrong input!!enter number between 20-98 only:93

The output is: 93 92 91 90 89 88

Enter the number between 20 and 98: 77

The output is: 77

Matlab In this assignment you will write a function that will calculate parallel resistance for up to 10 parallel resistors. Cal

Ket [755]

Answer:

The complete Matlab code along with step by step explanation is provided below.

Matlab Code:

function Req=ParallelR(Number)

Number=input('Please enter the number of resistors: ');

if Number>10 | Number<=0

disp('Invalid input')

return

end

R=0;

for i=1:Number

r=input('Please enter the value of resistor: ');

R=R+1/r;

end

Req=1/R;

end

Explanation:

Parallel resistance is given by

$\frac{1}{Req} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + \frac{1}{R_{3}}...+\frac{1}{R_{N}}$

First we get the input from the user for how many parallel resistors he want to calculate the resistance.

Then we check whether the user has entered correct number of resistors or not that is from 1 to 10 inclusive.

Then we run a for loop to get the resistance values of individual resistors.

Then we calculated the parallel resistance and keep on adding the resistance for N number of resistors.

Output:

Test 1:

Please enter the number of resistors: 3

Please enter the value of resistor: 10

Please enter the value of resistor: 20

Please enter the value of resistor: 30

ans = 60/11

Test 2:

Please enter the number of resistors: 11

Invalid input

Test 3:

Please enter the number of resistors: 0

Invalid input
