Can someone plz answer these questions

AfilCa [17]

Answer:

11001100 = 204

11111111 = 255

Explanation:

For 11001100:

1*2⁷ + 1*2⁶ + 0*2⁵ + 0*2⁴ + 1*2³ + 1*2² + 0*2¹ + 0*2⁰ = 204

Just replace 1's by 0's in the following calculation to do it for every 8 bit number:

1*2⁷ + 1*2⁶ + 1*2⁵ + 1*2⁴ + 1*2³ + 1*2² + 1*2¹ + 1*2⁰ = 255

If you don't want to do the calculation yourself, you can set the windows calculator in programmer mode, then select binary and key in the number.

Type two statements. The first reads user input into person_name. The second reads user input into person_age. Below is a sample

Sveta_85 [38]

How to answer this question really depends on the programming language.

In Delphi for example, you could have two text boxes, one for person_name and one for person_age:

person_name := textbox1.text;
person_age := StrToInt(textbox2.text);

In Delphi:
person_name=input('user input into person_name') person_age=int(input('user input into person_age'))

BorderLayout is the default layout manager for a JFrame’scontent pane

Tju [1.3M]

Answer:

True

Explanation:

BorderLayout is the default JFrame, JInternalFrame, and JApplet content panel layout manager.Border layout are used to arrange components(such as text fields, buttons, labels etc) in a particular manner.

Example

public class BorderLayout

extends Object

implements LayoutManager2, Serializable

These classes are used for making effective GUI(graphical user interface) in java.

Example for JFrame's content pane-

JButton button = new JButton("Button click (PAGE_START)");

/*making object JButton with a button name 'click*/

pane.add(button, BorderLayout.PAGE_START);

/*Adding Border layout in button*/

PAGE_START is BorderLayout constant,there are four more which defines the area-

PAGE_END

LINE_START

LINE_END

CENTER

. Write a function definition as follows: it returns the C++ form of a Boolean value, its function identifier is anyTwoTheSame,

Paraphin [41]

Answer:

The c++ code to implement the Boolean function is given. The function definition is shown.

bool anyTwoTheSame(float a, float b, float c)

{

bool same = false;

if(a == b)

same = true;

else if(a == c)

same = true;

else if(b == c)

same = true;

return same;

}

Explanation:

This function accepts three floating point numbers and returns true if any two numbers are equal else returns false.

The program below shows the implementation of this method.

#include <iostream>

using namespace std;

bool anyTwoTheSame(float a, float b, float c);

bool anyTwoTheSame(float a, float b, float c)

{

bool same = false;

if(a == b)

same = true;

else if(a == c)

same = true;

else if(b == c)

same = true;

return same;

}

int main() {

float one=12.34, two=56.78, three=90.1;

cout<<"Two numbers are same : " <<anyTwoTheSame(one, two, three);

}

OUTPUT

Two numbers are same : 0

The method is first declared.

bool anyTwoTheSame(float a, float b, float c);

Next step is method definition which shows what the function is supposed to do. The test to check equality of two numbers is implemented as shown.

bool same = false;

if(a == b)

same = true;

else if(a == c)

same = true;

else if(b == c)

same = true;

This is the simplest test which can be programmed.

If the numbers are not same, the Boolean variable, same, remains initialized to false.

This function is then called in main method.

No user input is taken as this is not specified in the question.

The three floating variables are declared and initialized inside the main. The values are put inside the program and not taken from the user.

The output shows either 0 or 1. 0 represents false and 1 represents true.

This program can be tested for different values of floating variables.
