Sergeu [11.5K]

Answer:

import java.util.Scanner;

public class num3 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter Favorite color");

String word1 = in.next();

System.out.println("Enter Pet's name");

String word2 = in.next();

System.out.println("Enter a number");

int num = in.nextInt();

//Point One

System.out.println("You entered: "+word1+" "+word2+

" "+num);

//Point Two

String passwordOne = word1+"_"+word2;

String passwordTwo = num+word1+num;

System.out.println("First password: "+passwordOne);

System.out.println("Second password: "+passwordTwo);

//Point Three

int len_passwrdOne = passwordOne.length();

int len_passwrdTwo = passwordTwo.length();

System.out.println("Number of characters in "+passwordOne+" :" +

" "+len_passwrdOne);

System.out.println("Number of characters in "+passwordTwo+" :" +

" "+len_passwrdTwo);

}

}

Explanation:

This question is solved using java programming language
The scanner class is used to receive the three variables (Two string and one integer)
Once the values have been received and stored in the respective variables (word1, word2 and num), Use different string concatenation to get the desired output as required by the question.
String concatenation in Java is acheived with the plus (+) operator.

Which of the following statements represents the number of columns in a regular two-dimensional array named values?

puteri [66]

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

<em>arrayname.length</em>

For example, to get the number of rows in array b above, we simply write;

<em>b.length </em>which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

<em>arrayname[0].length</em>

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

<em>b[0].length </em>which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length

Drag each statement to the correct location.

VMariaS [17]

Answer:

$(a)\ 222_{10} = DE_{16}$ --- True

$(b)\ D7_{16} = 11010011_2$ --- False

$(c)\ 13_{16} = 19_{10}$ --- True

Explanation:

Required

Determine if the statements are true or not.

$(a)\ 222_{10} = DE_{16}$

To do this, we convert DE from base 16 to base 10 using product rule.

So, we have:

$DE_{16} = D * 16^1 + E * 16^0$

In hexadecimal.

$D =13 \\E = 14$

So, we have:

$DE_{16} = 13 * 16^1 + 14 * 16^0$

$DE_{16} = 222_{10}$

Hence:

(a) is true

$(b)\ D7_{16} = 11010011_2$

First, convert D7 to base 10 using product rule

$D7_{16} = D * 16^1 + 7 * 16^0$

$D = 13$

So, we have:

$D7_{16} = 13 * 16^1 + 7 * 16^0$

$D7_{16} = 215_{10}$

Next convert 215 to base 2, using division rule

$215 / 2 = 107 R 1$

$107/2 =53 R 1$

$53/2 =26 R1$

$26/2 = 13 R 0$

$13/2 = 6 R 1$

$6/2 = 3 R 0$

$3/2 = 1 R 1$

$1/2 = 0 R1$

Write the remainders from bottom to top.

$D7_{16} = 11010111_2$

<em>Hence (b) is false</em>

$(c)\ 13_{16} = 19_{10}$

Convert 13 to base 10 using product rule

$13_{16} = 1 * 16^1 + 3 * 16^0$

$13_{16} = 19$

Hence; (c) is true

Programming CRe-type the code and fix any errors. The code should convert non-positive numbers to 1.

LUCKY_DIMON [66]

Answer:

Given

The above lines of code

Required

Rearrange.

The code is re-arrange d as follows;.

#include<iostream>

int main()

{

int userNum;

scanf("%d", &userNum);

if (userNum > 0)

{

printf("Positive.\n");

}

else

{

printf("Non-positive, converting to 1.\n");

userNum = 1;

printf("Final: %d\n", userNum);

}

return 0;

}

When rearranging lines of codes. one has to be mindful of the programming language, the syntax of the language and control structures in the code;

One should take note of the variable declarations and usage
