hoursWorked >= FULL_WEEK

Explanation:

The operator sign and meaning:

>  means greater than

<  means less than

=  equal sign

! means NOT operator

== means equal equal sign

Option a: hoursWorked >= FULL_WEEK

It means hoursWorked is greater than or equal to FULL_WEEK.

Option b: hoursWorked > FULL_WEEK

It means hoursWorked is greater than to FULL_WEEK.

Option c: hoursWorked == FULL_WEEK

It means hoursWorked is equal equal to FULL_WEEK.

Option d: hoursWorked != FULL_WEEK

It means hoursWorked is not equal to FULL_WEEK.

Therefore, Option a is the correct option.

The correct decision statement to check if 'hoursWorked' is greater than or equal to 'FULL_WEEK' is 'a. hoursWorked >= FULL_WEEK'. This includes scenarios where 'hoursWorked' is exactly a full week or more.

The decision statement that will correctly check whether hoursWorked is greater than or equal to the FULL_WEEK constant is:

a. hoursWorked >= FULL_WEEK

This statement checks if the variable hoursWorked is at least equal to the value of the FULL_WEEK constant. It covers both the scenario where hours worked are exactly equal to a full week and any amount of hours that is greater. In contrast:

Answer:

if(a < 10)

{ b = 0; c = 1;}

else

{ b = -99; c = 0;}

Explanation:

The if-else statement assigns values to variables b and c based on the condition whether a is less than 10. It assigns 0 to b and 1 to c if a < 10; otherwise, it assigns -99 to b and 0 to c.

This if-else structure is a fundamental concept in programming, allowing conditional execution of code based on whether a condition is true or false. For instance, if a equals 5, the values assigned will be b=0 and c=1, because 5 is less than 10. Conversely, if a equals 15, the assignments will be b=-99 and c=0.

Answer:

107₁₀ - 1101011

₂ (Binary representation)

200₁₀- 11001000₂ (Binary representation)

Explanation:

Converting from Decimal to binary:

Procedure -

1. Divide the number by 2, write the reminder separately.

2. Divide the divisor by 2, write the reminder before the previously written reminders.

Keep doing this till you get your divisor as 1.

Then we will write the divisor  before the written reminders and that will be the binary representation.

 For 107 :

          We divide 107 by 2 ,we get the divisor 53 and remainder 1

                                                  ( 1 )

Then,we will divide this divisor i.e 53 by 2,we get divisor 26 and remainder 1 ,we will put this remainder before the previous one.

                                                ( 1 1 )      

Then,we will divide this divisor i.e 26 by 2,we get divisor 13 and remainder 0 ,we will put this remainder before the previous one.    

                                                 ( 0 1 1 )

Then,we will divide this divisor i.e 13 by 2,we get divisor 6 and remainder 1 ,we will put this remainder before the previous one.    

                                                 ( 1 0 1 1 )

Then,we will divide this divisor i.e 6 by 2,we get divisor 3 and remainder 0,we will put this remainder before the previous one.    

                                                 ( 0 1 0 1 1 )

Then,we will divide this divisor i.e 3 by 2,we get divisor 1 and remainder 1  ,we will put this remainder before the previous one.    

                                                 ( 1 0 1 0 1 1 )

As we get the divisor=1,then we will stop.we will write the divisor before the written reminders.

                                              ( 1 1 0 1 0 1 1 )

This will be the binary representation of 107.

For 200 :

         We divide 200 by 2 ,we get the divisor 100 and remainder 0

                                                  ( 0 )

Then,we will divide this divisor i.e 100 by 2,we get divisor 50 and remainder 0 ,we will put this remainder before the previous one.

                                                ( 0 0 )      

Then,we will divide this divisor i.e 50 by 2,we get divisor 25 and remainder 0 ,we will put this remainder before the previous one.    

                                                 ( 0 0 0 )

Then,we will divide this divisor i.e 25 by 2,we get divisor 12 and remainder 1 ,we will put this remainder before the previous one.    

                                                 ( 1 0 0 0 )

Then,we will divide this divisor i.e 12 by 2,we get divisor 6 and remainder 0 ,we will put this remainder before the previous one.    

                                                 ( 0 1 0 0 0 )

Then,we will divide this divisor i.e 6 by 2,we get divisor 3 and remainder 0  ,we will put this remainder before the previous one.    

                                                 ( 0 0 1 0 0 0 )

Then,we will divide this divisor i.e 3 by 2,we get divisor 1 and remainder 1,we will put this remainder before the previous one.    

                                                 ( 1 0 0 1 0 0 0 )

As we get the divisor=1,then we will stop.we will write the divisor before the written reminders.

                                                 ( 1 1 0 0 1 0 0 0 )

This will be the binary representation of 200.

Answer:

The execution resumes in the finally block if one exists or otherwise from the next statement following the try...catch block.

Explanation:

Once an exception has been thrown and caught in the code, the execution continues with the statements in the finally block if one exists. If there is no finally block defined then execution resumes from the next statement following the try... catch block. For example:

try{

//An exception is raised

}

catch (Exception e){

//Exception is handled

}

System.out.println("After try...catch");

In this code segment, the next statement to be executed after catch is the System.out.println();

Answer:

#include <iostream>

using namespace std;

int main() {

float rainfall_inch,rainfall_mm;//declaring two variables of float type to hold the value rain in inches and mm.

cin>>rainfall_inch;//taking input of rain in inches..

rainfall_mm=rainfall_inch*25.4;//conveting inches to mm and storing in raingfall_mm.

cout<<rainfall_inch<<" inches = "<<rainfall_mm<<" mm of rain"<<endl;//printing the output.

return 0;

}

Explanation:

The above written program is in c++ for converting the rainfall in inches to mm.

I have taken two variables of type float to store the values of rainfall in inches and mm.

Conversion of inches to mm.

Printing the result.

Answer:

D - Finally

Explanation:

Once the program has executed and exited the try-catch structure (when all error handling is completed), it always executes the finally clause. The finally clause is best utilized when you want code executed even if the try structure finds an exception.

Answer:

3 3

Explanation:

The operator modulus '%' is gives the reminder of the number.

for example:

7%2  it gives the result 1 because 1 is reminder after divided by 2.

Initially the value of funny is 7 and serious is 15.

then, 15 is modulus by 2 which gives 1 and it store in the funny.

After that, if else statement check for condition.  

funny != 1  this condition is FALSE because Funny is equal to 1.

it moves to else if part Funny == 2 condition again FALSE it then move to else part and execute the statement Funny contain 3 and serious contain 3.

and then display.

Therefore, the answer 3 3.

The errors in the loop condition such that it is not giving desired results or it is not running accordingly.There are different types of loop errors which are as following:-

1.Infinite loop:-When the is not able to stop then the error is called infinite loop. for ex:-

int i=1;

while(i!=0)

{

cout<<"I am King"<<endl;

i++;

}

2.Off by one error:-This error mostly happens in loop for arrays as indexing of the array is from 0 to size-1 .So looping over the array up to the size is a off by one error.

3.Equality v/s assignment operator error:-In this error the condition in the loop is like this d=f which is wrong since = is assignment operator it assigns the value of f to d while d==f checks that the value of d and f are equal or not.

4.&& v/s || loop error:- In this error we use and operator (&&) instead of or operator (||) and vice versa.

symptoms of loop errors are not the desired output.

When you block statements, you must remember that any method you declare within a block is local to that block.

Each single statement in a Java program must be executed in the correct order. When all connected statements are enclosed in braces, we can sometimes produce a block statement that will be read as a single statement and allow us to use many statements to denote a single unit of work.

A compound statement that has been paired with a block statement is comparable.

When the class is loaded by JVM class loaders, the static blocks will only ever be executed once (Much like other static variables present at the class level).

Therefore, When you block statements, you must remember that any method you declare within a block is local to that block.

Answer:

Explanation:

We can deduce from the formula that any result from a positive integer for n will be divisible by 2, because of the following facts.

If n is an odd number, then n+5 will equal an even number. Also since an even number multiplied by an odd number equals an even number it is thereby divisible by 2.

Example: 3(3+5) ⇒ 3(8) = 24 (divisible by 2)

If n is an even number, then n+5 will equal an odd number, and as stated above any integer multiplied by an even number will equal an even number thus making it divisible by 2.

Example: 2(2+5) ⇒ 2(7) = 14 (divisible by 2)
