The goal of this coding exam is to quickly get you off the ground with HTML select element

Reference image:(final output)

https://assets.ccbp.in/frontend/content/dynamic-webapps/capital-and-country-op.gif

Test cases:

1.page should consist only one HTML span element with a non-empty text content

2.page should consist only one HTML paragraph element

3.page should consist of selected as HTML attribute for the HTML option element

4.JS code implementation should use addEventListenter with event as change

5.when the value of the HTML select element is changed ,then the text content in the HTML paragraph element should be the selected country name

6.page should consist only one main heading element

7.page should consist of HTML select element

8.page should consist of four HTML option elements with attribute as value.

pass the above all test cases....

5 case is not executed please help me

Write a C++ program that prints on the screen following diamond shape with given series of numbers. 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25.

C++ program that converts a decimal number to a binary, octal, and hexadecimal equivalents. First, the program will ask to fix a range for the lower and

upper limit in which the conversion is required. The lower limit should not be less than

0 and greater than the upper limit. For example, if you enter a negative number or

greater than the upper limit, then the program should print a message for the invalid

input and will ask you again to enter a decimal number within the range. If you

correctly specify the upper and lower limits, then the program will print a table of the

binary, octal and hexadecimal equivalents of the decimal numbers in the range of

lower limit through upper limit.

for while and do while loops must be used only once. anything else is not allowed to be used. functions can also be not used.

Example output:

Enter upper limit = 12

Enter lower limit = 30

Invalid.

Enter lower limit again = 10

Further table will be printed .

Assign your name to the variable name.

Assign your age (real or fake) to the variable age.

Assign a boolean value to the variable has_android_phone.

Create a dictionary person with keys "Name", "Age", "HasAndroidPhone" and values using the variables defined above.

Use a for loop to display the type of each value stored against each key in person.

A number is called a happy number, if you start with the given number

and arrive at 1 by repeating the following process (as illustrated in the below example): (a)

compute the sum of the squares of given number digits (b) if the resultant value is 1, then

the number is happy number, else execute point (a) for the newly produced number.

Note that if a number is not a happy number, there will be an endless loop to this execution.

Goal: In this question, you are required to write C++ code that checks whether the number entered by the user is a happy number or not for 10 cycles/iterations only.

Example: Assume a number 19

Number Computation Result cycle/iterations

19 1^2 + 9^2 82 1

82 8^2 + 2^2 68 2

68 6^2 + 8^2 100 3

100 1^2 + 0^2 +0^2 1 4

Write a program to find the table of numbers using a while loop. Your program should ask the size of the table. That size defines the rows and columns. Sample output:

IT must be done using WHILE loop.

Enter size: 6

1 2 3 4 5 6
