For beginners and seasoned programmers alike, creating impactful C++ projects can greatly enhance your portfolio by showcasing your programming skills and understanding of real-world applications. Here's a simple C++ project example that creates a basic calculator:
#include <iostream>
int main() {
double num1, num2;
char operation;
std::cout << "Enter first number: ";
std::cin >> num1;
std::cout << "Enter second number: ";
std::cin >> num2;
std::cout << "Enter operation (+, -, *, /): ";
std::cin >> operation;
switch (operation) {
case '+':
std::cout << "Result: " << num1 + num2 << std::endl;
break;
case '-':
std::cout << "Result: " << num1 - num2 << std::endl;
break;
case '*':
std::cout << "Result: " << num1 * num2 << std::endl;
break;
case '/':
if (num2 != 0)
std::cout << "Result: " << num1 / num2 << std::endl;
else
std::cout << "Error: Division by zero" << std::endl;
break;
default:
std::cout << "Invalid operation" << std::endl;
}
return 0;
}
Why Having a C++ Portfolio Matters

To-Do List Application
A To-Do List application emphasizes handling data and user interactions, making it perfect for beginners wanting to learn about CRUD operations (Create, Read, Update, Delete).
Project Overview: Users can add tasks, mark them as complete, and delete tasks as needed.
Code Example:
#include <vector>
#include <string>
class TodoItem {
public:
std::string task;
bool completed;
// Add methods here to manage tasks
};
Skills Demonstrated: This project allows you to explore object-oriented programming (OOP) and the management of collections through vectors.
Intermediate-Level C++ Projects
Personal Finance Manager
At the intermediate level, a personal finance manager project provides a deeper exploration of structured data management and user interaction.
Project Overview: The application helps users track income and expenses, offering insights into their financial health.
Data Structures and Algorithms Used: You can utilize linked lists or vectors to store transactions effectively.
Example Code Snippet:
struct Transaction {
std::string description;
