a) Select whether the statement is True or False. i. A stack is a data structure in which the items can be added and deleted from both ends of the structure. (True / False) ii. The basic operations on a stack are as follows: Push an item onto the stack, pop an item from the stack, retrieve the top element of the stack, initialize the stack, check whether the stack is empty, and check whether the stack is full. (True / False) i. The middle elements of a stack could be accessed directly. (True / False) iv. Postfix notation does not require the use of parentheses to enforce operator precedence, and the operators are written after the operands. (True / False)

POINTERS-DYNAMIC ARRAY- EXCEPTION HANDLING POINTERS: GRADE ELIMINATION. A program that will input 10 score for quizzes (0-100) .Get the lowest quiz and eliminate the lowest quiz and compute and output the average of the 9 remaining quizzes. Finally, output only the SUM, LOWEST GRADE and the AVERAGE. DYNAMIC ARRAY & EXCEPTION HANDLING: COMPUTE FOR MILES PER GALLON Make a program that will calculate and compute for the quotient of miles and gallons (mpg: miles per gallons). Your program should must ask the user to specify the size of the array (using dynamic array) for the following variable: miles ,gallons and mpg. Prompt the user to Initialize the value of miles (value for miles should be 100-250) and gallons (values should be from 5-25). Use pointer galPtr for gallons, milPtr for miles and mpgPtr for mpg. Use function MilesPerrGallon (double,double) to compute for the values of mpg and use exception handling try-throw-catch to validate the values of miles and gallons.…
Provide the code in Java language: Assignment 7: To-Do & Done List You need to use arrays, loops, menus and input/output to make a to-do list program. The user should be able to add/remove items from the list and be able to place them where he would like on the list: The user should have a menu. The menu should let them add items, mark the item as done, view the list or clear the list. Be sure to have: (after they select an item from the menu, they should get all of the options presented to them again). If an item is added to the list. It should be added into a list at the location that the user says. Hint: “you need to prompt for where on the list”. You can move items back if necessary. When the user marks an item as done. It should be moved to the done list and removed from the to-do list altogether. There should be a sentinel value to leave the program. When the sentinel value is entered in. The program should display the to-do list and done list together.
Data structure/ C language / Graph / Dijkstra’s algorithm implement a solution of a very common issue: howto get from one town to another using the shortest route.* design a solution that will let you find the shortest paths betweentwo input points in a graph, representing cities and towns, using Dijkstra’salgorithm. Your program should allow the user to enter the input filecontaining information of roads connecting cities/towns. The programshould then construct a graph based on the information provided from thefile. The user should then be able to enter pairs of cities/towns and thealgorithm should compute the shortest path between the two cities/townsentered.Attached a file containing a list of cities/towns with the following data:Field 1: Vertex ID of the 1st end of the segmentField 2: Vertex ID of the 2nd of the segmentField 3: Name of the townField 4: Distance in KilometerPlease note that all roads are two-ways. Meaning, a record may representboth the roads from feild1 to field2…
Identify the difference between STACK and ARRAY.
C++ Fast please Write a program in C++ to do the following tasks. a) Read a number N from the user. b) Using recursion generate and find sum of the numbers which are divisible by 3 starting from N and ends with 0. c) Print the numbers and sum as shown in the below output. Note: A number is divisible by 3 if the remainder after dividing the number with 3 is zero. Sample output 1: Enter a number: 15 15 Numbers are: 12 sum of the numbers are:45 Sample output 2: Enter a number: 20 Numbers are: 18 15 sum of the numbers are:63 12 3 6 3 8

Data Structure Using C++ (Queue) c++ code C++ PROGRAMMING LANGUAGE PLEASE :: We can use a queue to simulate the flow of customers through a check-out line in a store. In this simulation we will have the following details: one check-out line the expected service time for each customer is one minute (However, they may have to wait in line before being serviced) between zero and two customers join the line every minute We can simulate the flow of customers through the line during a time period n minutes long using the following algorithm: Initialize the queue to empty. for ( minute = 0 ; minute < n ; ++minute ) { if the queue is not empty, then remove the customer at the front of the queue. Compute a random number k between 0 and 3. If k is 1, then add one customer to the line. If k is 2, then add two customers to the line. Otherwise (if k is 0 or 3), do not add any customers to the line. } In addition, the algorithm will keep track of the following:…
