  • Should I apply for a credit card agian?

    I recently applied for a citi Thank you card and I was declined because my annual income is too low. I am currently in college with a part time job. I decided to apply for the regular citi thank you card because I am graduating soon. Now that I have been declined can I apply for the citi thank you card for college students instead? Or should I wait?

  • Discrete Math Question?

    I am reviewing for an exam and I have come upon 5 problems that I'm having trouble with. It would be great help if someone can assist me with these 5 problems. Thank you!

    1. ∀xp(x) ∧∀yp(y)≡

    2. 2. Apply the resolution rule to the statements p v q v r and p v ~q v s

    3. If s is a rational numbers, is s2 always a rational number? If it is, give a proof. If it isn’t, give a counterexample.

    4. In the domain of integers, If n2 is even, is n always even? If it is, give a proof. If it isn’t, give a counterexample.

    5. Let x < y have the usual meaning in the domain of real numbers (“x is strictly less than y”). Write a predicate logic statement that means “Among any two different numbers one of them is strictly less than the other.”

  • 2014 Mazda 3?

    I'm in the market to purchase a 2014 Mazda 3 S Grand Touring Hatchback. There is a Mazda dealer near where I live that has a special on a new 2014 Mazda 3 S Grand Touring sedan. The special is as follows:

    2014 Mazda 3 S Grand Touring Sedan

    MSRP: $26,790

    Dealer Discount: -$2000

    Sale Price: $24,790

    Owner Loyalty Rebate: -$1000

    NET COST: $23,790

    I'm curious, can this discount be applied to a 2014 Mazda 3 S Grand Touring Hatchback? The hatchback has the exact MSRP as the sedan at $26,790. Also what is an owner loyalty rebate? Thank you!

    I am writing a program that requires a 1.Class specification file (header file) and 2. a Implementation File. I have finished writing my 1. Class Specification file and I was wondering if someone can check correct if I wrote my 2. Implementation file correctly. I have posted the assignment below and my codes below.

    **************Assignment**********

    Book Store Program

    You would like to write a program that functions similarly to a book store data base. Your program should read book data

    from an inventory file called books.dat that contains best selling book titles, prices, and number of copies. Your program

    should store this data in a linked list (each node will contain a title, price, copies, and link to another node).

    Your program should allow a user (book store owner) to do several things:

    * Type in a title and retrieve the number of copies available.

    * Find titles that need to be reordered - this should be done if the number of copies is less than 10.

    * Delete a book and its inventory

    * Print the book titles in order of price (least to greatest)

    * print the list of inventory (all fields).

    Add each routine individually and test it before going on to another routine.

    ************* 1. My Class specification file (header file)****** CORRECT

    My teacher wrote this code in class but he is not going to be in class for the rest of the week. Can you please help me interpret this code. Thank you!

    #include <iostream>

    #include <string>

    #include <vector>

  • C++ help with structure program.?

    I need help writing a program that uses a structure to store the following data about a customer account:

    Customer name

    Customer address

    City

    State

    ZIP code

    Telephone

    Account balance

    Date of last payment

    This program should use an array of at least 20 structures. It should let the user enter data into the array, change the contents of any element, and display all the data stored in the array. The program should have a menu-driven user interface.

    Prompts And Output Labels. Your main menu should be the following:

    1. Enter new account information

    2. Change account information

    3. Display all account information

    4. Exit the program

    The user is expected to enter 1 or 2 or 3 or 4.

    The main menu is displayed at the start of the program and after the handling of choices 1, 2 and 3.

    If 1 is entered for the main menu, the program prompts for each of the data listed above, in the order listed above, using the above data descriptions (e.g. "ZIP code") as prompts (followed in each case by a colon). After reading in and processing the data, the program prints

    You have entered information for customer number X

    where X is the customer number: 0 for the first customer and increasing by 1 for each subsequent customer that is entered.

    If 2 is entered for the main menu, the program prompts for the customer number:

    Customer number:

    Upon entering a valid customer number the program displays all the data for the particular customer that has been saved:

    Customer name: ...

    Customer address: ...

    City: ...

    State: ...

    ZIP code: ...

    Telephone: ...

    Account balance: ...

    Date of last payment: ...

    The program then skips one or two lines and prompts for a change, using the same prompts as in choice 1 above for all the data items associated with a customer.

    If 3 is entered for the main menu, the program displays all the data for each customer that has been saved, using the display format in choice 2 above. After the display of each customer the program prompts "Press enter to continue..." and waits for the user to hit return.

    If 4 is entered for the main menu, the program terminates.

    Input Validation (OPTIONAL).When the data for a new account is entered, be sure the user enters data for all the fields. No negative account balances should be entered.

    Thank you! I am really struggling with this program.

  • I need help with this C++ program. Thank you?

    I have the catinthehat.dat file. I just need help with the coding part. Thank you!

    Write a program with three functions: reverse, upper, lower.

    Like upper and lower, reverse should also accept a pointer to a c-string. As it steps through the string, it should test each character to determine whether it is upper or lowercase. If a character is uppercase, it should be converted to lowercase. Likewise, if a character is upper case it should be converted to lowercase.

    The upper function should accept a pointer to a c-string as an argument. It should step through each character in the string, converting it to uppercase.

    The lower function, to should accept a pointer to a c-string as an argument. It should step through each character in the string converting it to lower case.

    Test on a file called: catinthehat.dat

    Count each character as it is read into the file and then dynamically allocate an array that will hold these characters

    =>Pass the array to the functions in the following order: reverse, lower, and upper.

  • I need help with a couple C++ questions.?

    1) Write a function that accepts a pointer to a C-string as its argument. The function should count the number of times the character ‘w’ occurs in the arguments and return that number.

    2) Write a function that takes a char array as a parameter. The function should go through the array and count how many chars are alphabetic, digits, or punctuation.

    3)Write a function that converts a lowercase letter to upper case and upper case to lower case. The function should return the changed character.

    4) Write a function that takes a character array and its size as a parameter. The function should dynamically allocate a new array that is twice the size of the parameter array. It should then copy the items in the parameter array to the new array. The function should return a pointer to the new array.

    5) Write a function that sums all the columns of a 4 by 3 array of integers.

    6) Write a function that takes a 1-D array of chars and a single char. The function should locate the single char in the array using a binary search and should return true if the char is found or false if it is not.

  • I need help with this C++ programing. Thanks?

    Can some one please check my code. I have a few errors that I can not get rid of. Please check my work to see if I have done it correctly and some feed back please. Thanks!

    Here are the instructions to this program:

    Write a program that reads 20 names from a file called names.dat and stores them in two different arrays (eg names1, names2). Print the unsorted array then modify the selection sort routine so that it sorts the 20 names in the first array. Count how many swaps are needed to sort the 20 names. Print the sorted array contents and the number of swaps needed.

    Next, sort the second array with the bubblesort routine. Count how many swaps are needed to sort the array with bubblesort. Print the unsorted array and the sorted array as you did previously along with the number of swaps needed.

    Use functions for a well structured program and don't forget your name and program description.
