The program to this question as follows:

Program:

#include <iostream> //defining header file

using namespace std;

int main() //defining main method

{

int x = 10,y = 20,z = 30; //defining integer variable and assigning the value

int sum;//defining integer variable sum  

sum =x+y+z;//adding value,that holds by sum variable  

cout<<"sum: "<<sum; //print value

return 0;

}

Output:

sum: 60

Explanation:

Description of the above code as follows:

  • In the above code three integer variable "x, y, and z" is declared, that initialized with the value, that is 10, 20, and 30.
  • In the next line, another variable "sum" is declared, that holds the above variable value and add the number.
  • Then the print function "cout"  is used, which prints sum variable value.

Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week,
quester [9]

Answer:

<em>Jamie earned (Total pay)  $500.</em>

<em></em>

Explanation:

We are given the following code:

<em>If (Rate >=10) OR (Hours <=40) Then </em>

<em>    TotalPay = Hours * Rate </em>

<em>Else </em>

<em>    TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5 </em>

<em>End If</em>

<em />

Let us understand the code line by line:

The first line contains an if statement with 2 conditions:

i.e. 1st condition:

The rate is greater than or equal to 10

2nd condition:

Number of hours are lesser than or equal to 40.

There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.

The next statement is:

TotalPay = Hours * Rate

It calculates the pay if any of the two conditions written earlier becomes true.

Next statement is else statement:

It will get executed given that the above if() statement becomes false.

Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:

i.e.

Hours = 50

Rate = 10

Now, let get to the code execution.

The first condition is true i.e. Rate >= 10 (because Rate is 10 here)

So, the following statement will be used to calculate the Total pay:

TotalPay = Hours * Rate

and else part will not be executed.

TotalPay = 50 * 10  =<em> $500  </em>

<em></em>

<em>Jamie earned (Total pay)  $500.</em>

Iven the code fragment below with nested if statements, rewrite the code to combine all the tests into one if statement with mul
Georgia [21]

Answer:

See Explanation Below

Explanation:

The new code segment is

int feb = 28;

if ((year % 4) == 0 && (year % 100) != 0) // assume that year is an integer with a valid year value

{

System.out.println("This is a leap year");

feb = 29;

}

Assume year = 2020, the assigned value of feb is 29;

Reason below;

At line 2 of the new code segment, two conditions are tested both of which must be satisfied.

1. year % 4 == 0

2020 % 4 = 0

0 = 0 (True)

2. year % 100 != 0

2020 % 100 != 0

20 != 0 (True)

Since both conditions are true, the value assigned to feb will be 29 and

"This is a leap year" will be printed without the quotes
