(Emirp) An emirp (prime spelled backward) is a nonpalindromic prime number whose reversal is also a prime. For example, 17 is a prime and 71 is a prime, so 17 and 71 are both emirps. Write a Java program that displays the first 100 emirps. Display 10 numbers per line with a spacing of 5; all numbers should be left-aligned.

A criticism of the break and continue statements is that each is unstructured. These statements can always be replaced by structured statements. Describe in general how you’d remove any break statement from a loop in a program and replace it with some structured equivalent. [Hint: The break statement leaves a loop from within the body ofthe loop. Another way to leave is by failing the loop-continuation test. Consider using in theloop-continuation test a second test that indicates “early exit because of a ‘break’ condition.”] Use the technique you developed here to remove the break statement from the program (c++ language)

( MindTap - Cenage )Example 5-6 implements the Number Guessing Game program. If the guessed number is not correct, the program outputs a message indicating whether the guess is low or high. Modify the program as follows: Suppose that the variables num and guess are as declared in Example 5-6 and diff is an int variable. Let diff = the absolute value of (num - guess). If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number. Suppose diff is not 0. Then the program outputs the message as follows: If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num). If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num). If diff is greater than or equal to 15 and less than 30, the…

Write the following

(Hard drive storage capacity) If you buy a 40 GB hard drive, then chances are that the actual storage on the hard drive is not 40 GB. This is due to the fact that, typically, a manufacturer uses 1,000 bytes as the value of 1K bytes, 1,000 K bytes as the value of 1 MB, 1,000 MB as the value of 1 GB. Therefore, a 40 GB hard drive contains 40,000,000,000 bytes. However, in computer memory,1 KB is equal to 1,024 bytes, and so on. So the actual storage on a 40 GB hard drive is approximately 37.25 GB. (You might like to read the fine print next time you buy a hard drive.) Write a program that prompts the user to enter the size of the hard drive specified by the manufacturer, on the hard drive box, and outputs the actual storage capacity of the hard drive.

(Use DevC++) 1. Concert Tickets Sale and Charity Donation Program Design and implement a program that prompts the user to input the concert name, ticket price,number of tickets sold, and percentage of the gross amount to be donated to the charity. The sampleoutput is as shown below: Sample Output:**************************************************************************Concert Name: ………………………………..… The Concert at the ParkTicket Price: …………………………………..… P 49.75Number of Tickets Sold: ………………….…. 5,985 pcs.Gross Amount: ………………………………….. P 297, 753.75Percent of Gross Amount Donated: ……… 13.00%Amount Donated: …………………………..…. P 38, 707. 9875Net Sale: ………………………………………….. P 259, 045.7625************************************************************************** Note that the concert name such as “The Concert at the Park” must be declared as String.

Determine the precise (i.e., not just the order of magnitude) Big-Oh values for the following code sample, based on the number of statement executions, as described in the Module 1 lecture. Choose the answer that best agrees with the value you have determined. Keep the following considerations in mind: Remember to consider each statement in compound statements separately. Pay close attention to the initial and end values of loop variables! Loops such as "for" and "while" contain an implicit "jump" instruction that causes execution to proceed from the end of the loop back to the beginning of the loop. Code sample: for (int i = 0; i < n; i++) { sum += i; } int j = 0; while (j < n) { sum--; j++; }
