Part 1: Complete the survey. Part 2: Peek-a-boo is a fun game that little kids like to play. To simulate this game on the computer, write a program that will generate a random number between 1 and 4. Then, will print to the screen the animal name associated to that number. The animal names used will be: pig when a 1 is generated cow when a 2 is generated chicken when a 3 is generated horse when a 4 is generated If your program generates a 3, the output will be: chicken The player will then enter a 1 if they would like to play again or anything else to exit the program. If the player enters "1 1 1 0", the output will be: horse chicken cow horse For coding simplicity, follow each output animal by a space, even the last one. Hint: To make testing easier, seed your random number generator with 0.
Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the rectangle centred at (1, 1)with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4)is outside the rectangle, as shown in Figure . (Hint: A point is in the rectangleif its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its verticaldistance to (0, 0) is less than or equal to 5.0 / 2. Test your program to cover allcases.) Here are two sample runs. Enter a point with two coordinates: 2 2 ↵EnterPoint (2.0, 2.0) is in the rectangle
Write a program that prompts the user to enter the number of students and each student's name and score, and finally displays the student with the highest score and the student with the second-highest Score. Assume that the number of students is at least 2. Sample Run Enter the number of students: 5 Enter a student name: Smith Enter a student score: 60 Enter a student name: Jones Enter a student score: 96 Enter a student name: Peterson Enter a student score: 85 Enter a student name: Greenlaw Enter a student score: 98 Enter a student name: Zhang Enter a student score: 95 Top two students:
Part A: Create a program that prompts the user to input the retail price of an item. Next, prompt them to enter the current discount for the item as a percentage. Then, output the new price with discount applied. A sample program run follows: enter the retail price : 55.75 enter the discount ( as a percentage ) : 12 the discounted price is 49.06 Part B: Create a program that prompts the user to input 4 quiz scores, then outputs the average of the scores. Be sure to format your output to display 1 place after the decimal.
3. The bin packing problem is to pack the objects of various weights into containers. Assume that each container can hold a maximum of 10 pounds. The program uses an algorithm that places an object with the largest weight into the first bin in which it would fit. Your program should prompt the user to enter the total number of objects and the weight of each object. The program displays the total number of containers needed to pack the objects and the contents of each container. Here is a sample run of the program: Enter the number of objects about itinerary with the following members: 1. A data field named flgihts of the List type. The list contains the flights for the itinerary in increasing order of departure Time. A constructor that creat: 6 Enter the weights of the objects: 7 5 2 3 5 8 Container 1 contains objects with weight 8 2 Container 2 contains objects with weight 7 3 Container 3 contains objects with weight 55
5. Write a program that will ask the user to input a letter 'm' or 'f and then it will display "Hello Sir" if the input is 'm' otherwise, "Hello Madam".
6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.
Given an airplane's acceleration and take-off speed v, you can compute the minimum runway length needed for an airplane to take off using the following formula. length=v^2/2*a. write a program that prompts the user to enter V in meters and acceleration an in meter/second and display the minimum runway length.
