C867 is WGU's applied C++ course: you move from reading about programming to building a working object-oriented program.
WGU describes Scripting and Programming - Applications as exploring the various aspects of the C++ language by examining its syntax, the development environment, and tools and techniques to solve real-world problems. It is an undergraduate course in WGU's IT and software programs.
Students coming from Python often find C++ unforgiving. Header files, pointers and manual memory management add steps that higher-level languages hide, and a single missing semicolon or mismatched declaration can stop a build.

What C867 Covers
- Syntax and data types: variables, operators, strings and type conversions.
- Control structures: if statements, loops and switch.
- Functions: parameters, return values, passing by value and by reference.
- Arrays and pointers: fixed arrays, pointer arithmetic and dynamic allocation.
- Classes: constructors, destructors, accessors, mutators and encapsulation.
- Development environment: projects, header and source files, compiling and debugging.
Key Concepts Explained
Headers and Source Files
In C++, a class is usually declared in a header file (.h) and defined in a source file (.cpp). The header tells other files what exists; the source file says how it works. Include guards or #pragma once stop a header being processed twice.
Example: book.h declares class Book { public: Book(std::string t); std::string getTitle() const; private: std::string title; };. book.cpp includes book.h and defines std::string Book::getTitle() const { return title; }. main.cpp includes only book.h.
Pointers and Dynamic Memory
A pointer stores an address. Objects created with new live until you call delete. A class that allocates memory should free it in its destructor, or the program leaks memory.
Example: A Library class holds an array of Book*. Its constructor fills the array with new Book(...); its destructor loops through the array and calls delete on each pointer.
Parsing Input Strings
Many C++ exercises ask you to split a comma-separated string into fields. The usual tools are find() and substr(), or a stringstream with getline and a delimiter. Converting numeric fields needs stoi or similar.
Plan Before You Code
Ten minutes of planning saves hours of debugging. Before writing code, list each class with its data members and functions, then sketch how main() will use them. Write the function signatures first, compile the empty shells, and only then fill in the bodies.
Example: For a program that stores course records, the plan might read: Course (code, title, credits, getters, setters, print); Catalog (array of Course pointers, count, add, remove by code, print all, destructor); main (create Catalog, parse input strings, call each function in the required order).
This plan doubles as a checklist when you compare your program with the requirements.
Typical Tasks and How to Approach Them
Check your course page for the current performance task. Work in a course like this typically involves:
| Task element | What it tests | How to approach it |
|---|---|---|
| Class design | Encapsulation | Private data, public getters and setters |
| Data parsing | String handling | Test with one record before looping |
| Container class | Arrays and pointers | Track the count; free memory in the destructor |
| Required output | Following specifications | Match function names and output exactly |
Debugging Habits That Save Hours
Compile early and often. Fix the first error in the list, rebuild, then look again, since later errors often cascade from the first. Use the IDE debugger to step through a loop and watch variables instead of guessing.
Common C867-style errors include declaring a function in a header but misspelling it in the source file, forgetting ClassName:: before a member definition, and reading past the end of an array. Learning to read linker errors ("undefined reference") is as useful as learning syntax.
Where Students Get Stuck
- Linker errors. Usually a declaration and definition do not match exactly.
- Memory management. Every
newneeds a matchingdelete. - Specification drift. Renamed functions or extra output can fail a requirement even if the program works.
- Starting too big. Writing the whole program before compiling hides where errors begin.
Study Tips for C867
- Build in small steps: one class, compile, test, then the next.
- Keep the requirement list beside you and tick each item when it works.
- Comment why, not what: future you needs the reasoning.
- Practice pointers on tiny programs before using them in the project.
How We Help with C867
Send the requirements, your code and any error messages or evaluator comments. A C++ tutor explains concepts, walks through errors, reviews your design and suggests improvements, so you understand and finish the code yourself.
GradeEssays is independent of Western Governors University. We do not write code for you to submit as your own, take assessments or log in to student portals. Our help is tutoring and code review under WGU's academic integrity rules. Every order comes with free revisions within the scope of your original request.

Frequently Asked Questions
C++. WGU describes the course as exploring C++ syntax, the development environment, and tools and techniques for real-world problems.
It helps to have taken WGU's earlier scripting and programming foundations material. Check your degree plan for the recommended order.
A function is declared but not defined, or the definition does not match the declaration exactly. Check names, parameters, const and ClassName::.
Free every dynamically allocated object, usually in the destructor of the class that created it.
No. We explain concepts, review your code and help you debug so you can complete it yourself.
No. We are independent and not connected with Western Governors University.
