๐ Challenge 1: Student Grade Manager
Build a system that stores students with grades, calculates averages, assigns letter grades, and ranks students. This challenge tests OOP, sorting, and data formatting.
Skills tested: Classes, vectors, sorting with lambdas, string formatting, basic I/O
Challenge 1: Grade Manager
Build a student ranking system โ then extend it!
#include <iostream>
#include <string>
#include <vector>
#include <map>
#include <algorithm>
using namespace std;
// CHALLENGE 1: Student Grade Manager
// Build a system that stores students and their grades,
// calculates averages, and ranks them.
struct Student {
string name;
vector<int> grades;
double average() const {
if (grades.empty()) return 0.0;
double sum = 0;
for (int g : grades) sum += g;
return sum / grades.size();
}
char letterG
...๐ Challenge 2: Command-Line Task Manager
Create a project management tool with tasks, priorities, assignees, and status tracking. This challenge tests enums, filtering, and structured output.
Skills tested: Enums, vectors, filtering, formatted output, state management
Challenge 2: Task Manager
Build a task tracker โ then add persistence and undo!
#include <iostream>
#include <string>
#include <vector>
#include <memory>
#include <sstream>
using namespace std;
// CHALLENGE 2: Command-Line Task Manager
// A mini project management tool with tasks, priorities, and filtering
enum class Priority { LOW, MEDIUM, HIGH, CRITICAL };
enum class Status { TODO, IN_PROGRESS, DONE };
string priorityStr(Priority p) {
switch (p) {
case Priority::LOW: return "Low";
case Priority::MEDIUM: return "Medium";
case Priority::HIGH:
...๐ Challenge 3: Text Analyzer
Analyze text for word frequency, sentence statistics, and readability. This challenge tests string processing, maps, and algorithm design.
Skills tested: String manipulation, unordered_map, sorting, statistics, algorithm design
Challenge 3: Text Analyzer
Analyze word frequency and readability โ then add bigrams!
#include <iostream>
#include <string>
#include <unordered_map>
#include <vector>
#include <sstream>
#include <algorithm>
using namespace std;
// CHALLENGE 3: Text Analyzer
// Analyze text for word frequency, sentence count, and readability
class TextAnalyzer {
string text;
vector<string> words;
unordered_map<string, int> freq;
string toLower(string s) {
transform(s.begin(), s.end(), s.begin(), ::tolower);
return s;
}
string cleanWord(const string& w) {

Development Tips
- Start small: Get a minimal working version first, then add features iteratively.
- Write tests: Test each function as you build it. Bugs compound โ catch them early.
- Use version control: Commit after each working feature. Git is essential for any project.
- Read other code: Study open-source C++ projects on GitHub to learn professional patterns.
- Compile with warnings: Always use
-Wall -Wextra -Wpedanticโ they catch bugs for free.
