Hello Programmers! I am working on a C++ phone number class. The class has overloaded stream manipulators, cin and cout for output. It has three private members: areaCode, exchange, and line, strings that represent the numbers that are used in a telephone call. It is supposed to default to (000) …
Here are some of mine: * Make A Player vs. Computer Connect Four Computer Game (Intermediate) * Make a Player vs. Computer battleship game (Intermediate) * Create a Simulation of the Knight Tour (where the computer provides the steps for a knight to conduct one- search on the internet for …
Hi all! Whenever I am working with my code in my main.cpp file, I can call character-handling functions like * isdigit * isalpha * isspace * toupper without importing the `cctype` library. However, my C++ How to Program Book shows that the cctype library must be imported before the functions …
Hello all! I am trying to take a string that has mixed uppercase and lowercase chars and then convert it to lowercase. I am doing the following line of C++ code: transform(theReadMessage.begin(),theReadMessage.end(),theReadMessage.begin(),theReadMessage.end(),::tolower); //theReadMessage is a string to convert to lowercase and my C++ xCode debugger gives me this message `Too …
Hi all! I am working on creating an SMS language translator (SMS -> real English), and I am having trouble initializing a map for the SMS -> English codes.

Hello all! When would it be advisable to use string iterators vs the "for char c in string" loop that is a feature in C++-11 or vs the for (int i.....) loop? And why? The only two situations I see myself using string iterators is for the STL algorithms and …
Hello all! I am working through a book here and it says that there is a class-template "basic_string" that is used in the namespace std as `typedef basic_string<char> string;` to create an alias for the "string" type. However, I know that there is a header file `<string>` for the declaration …
Hello Programmers! I am trying to write a recursive implementation of the quicksort algorithm in C++. I believe you all know what it is so I shall not go into the details. However, I run this, but it never ends. Going through it with a debugger shows that my partitioning …
I tried to restore my jailbroken iPad to factory settings. I clicked on the jailbroken device with iOS7 "restore to factory settings," and now it is loading for more than 8 hours (duing night). I was told that this was normal... but I do not believe it. All I have …
Is it poor convention to create a c++ file only to store various functions, and then include it into the main.cpp? This would be done so that the functions could be used in different programs as well.
Hello programmers! I am working on a program that checks if a user's input is a palindrome (in this case, the input is a string). I am using a custom class template "stack", that is a constrained version of my custom class "List", which is a linked list class template. …
Hellp programmers! I am working on a program that uses two objects of a custom class template List [which is a linked list, with each item pointing to the next] and concatenates them. Initially, I need to input numbers into my main function, so I have two sets of while …
Hello programmers! I am working on a custom tree class [with the code example being copied from Dietl's C++ How to Program, 9th edition]. It is in my fashion to copy all the code examples in the book when reading it (for muscle memory), but the authors created a custom …
Hi programmers! I am trying to grasp the concept of friendship. Let's say that we have the following: class List; //forward declaration class ListNode { friend class List; //make List a friend /* rest of code here, blah, blah, blah. */ } Does this mean that ListNode can access Lists's …
Hello! I was creating a custom array class as an exercise in my exploring of class and function templates. Here's my header file: #include <iostream> template <typename el> class Array { friend std::ostream &operator<<(std::ostream&,const Array&); friend std::istream &operator>>(std::istream&,Array&); public: Array(const int& arraySize=0); //set all members of array with size arraySize …
Hello programmers! I recieved the following assignment to do in C#.net: It is a class that: * Accepts an HTML report string * Converts the HTML string into a PDF file using PDF Creator (free open source library) What are some utilities that I will need to use? I so …
Hello programmers! I have been working on STL algorithms for some time now as a beginner, and I started doing an exercise, among which is the task of `use the fill algorithm to fill the entire array of strings named items with "hello"`. My code for this is below: // …
I was just wondering, what is a good rule of thumb for industrial-grade code when deciding whether to use the std::array template vs a built-in array?
Hello programmers! After covering the basics of STL, I decided to complete the following assignment: `Write a function template palindrome that takes a vector parameter and returns true or false according to whether the vector does or does not read the same forward a backward.` So, for example, a vector …
Hello programmers! I am having a function that has the user enter a name for an object, check if its valid, and return it if it is. I am getting the input via getline, but it seems that you have to press enter twice to make the input work. Here's …
Hello programmers! I have been working on a hardware store application, where there is a `HardwareRecord`class that stores information about each object in a store (ex: nuts, bolts, screws, and so forth). Here's my declaration of this class: // HardwareRecord.h // Initialize Hardware Store File // // // Definition of …
I would not advise that, as I don't believe that there are websites with solid programming exercises.. I would advise a solid book, such as "C++ How to Program" which has many solid exercises at the back of the book, or "Eventful Java". Yes, I know they may be overpriced, …
Hello programmers! I was working on a program that reads a sequential file with bank accounts. The file has three sets of data per line: the account #, the account holder's name, and balance. Then, I made a program to print the file- and it printed the last line of …
What is the intended purpose of these nestled loops, along with the if-statements? I do not see any comments. Could you bother to explain your code?
Hello Programmers! I am working on a 'comics' page of my website. It is going to have multiple pictures (arranged neatly in a table) for the viewer to see and enjoy. I would like to have the images (by default) have a width of 10% of the browser window's width …

Hello programmers! I am working on a Tic-Tac-Toe player vs. computer class, which is supposed to have a `run.()` method in order for the game to start. In a `gameWon()` member function, I am checking for a win, either by the player or by the computer. I check to see …
Hello Programmers! How can I throw an exception if an unsigned int variable overcomes a limit (that is set by myself). I want the exception to terminate all processes. Thanks!
Hello programmers! I am making a player vs. computer Tic-Tac-Toe game in xCode that is a class, with its `run()` method as its only public member function apart from the initializer. I want to decide whether the player goes first, and I created a function to do that called `determineFirst()`. …
Hello Programmers! How can I convert a double to a string without losing its precision (i.e. values after the decimal point)? Thanks!
Hello Programmers! I am making a program that demonstrates the difference between passing by value to a function and passing by reference.

Hello programmers! I am trying to return an array, made up of 7 members, all type ints via a pointer from a function. Here is a prototype of a function that does this: `int[7] colCountArray={0,0,0,0,0,0,0} //array saved in Board obj.` int* Board::accessColCount() { return &colCountArray; } However, my compiler dosnt …
Hello programmers! I am creating a player vs. computer connect four game. It has full interactivity along with error checking for invalid inputs by the player.
