|
||||
|
||||
## ⚠️ Areas for Improvement
|
||||
|
||||
### 1. **Data Types (C++ vs Other Languages)**
|
||||
**Question Q4: Which are valid C++ data types?**
|
||||
- **Your answer:** A (int), B (boolean), C (float), D (char)
|
||||
- **Correct answer:** A (int), C (float), D (char)
|
||||
- **Issue:** Selected "boolean" - C++ uses `bool`, not `boolean`
|
||||
- **Score:** 6.67/10 (partial credit for 3 correct, 1 wrong)
|
||||
|
||||
**Why this matters:**
|
||||
- C++ uses `bool` keyword, not `boolean` (like Java)
|
||||
- Common confusion between languages
|
||||
- Important for type declarations
|
||||
|
||||
**Recommendation:**
|
||||
- Review C++ fundamental data types
|
||||
- Note differences from Java/JavaScript (`bool` vs `boolean`)
|
||||
- Practice type declarations
|
||||
|
||||
**Study Resources:**
|
||||
- C++ Learning Plan: Module 1.2 (Basic Syntax & Types)
|
||||
- cppreference.com - Fundamental types
|
||||
|
||||
---
|
||||
|
||||
### 2. **References (Honest Knowledge Gap)**
|
||||
**Question Q20: Which are true about references in C++?**
|
||||
- **Your answer:** "I don't know"
|
||||
- **Correct answer:** A, C, D
|
||||
- A: References must be initialized when declared ✓
|
||||
- C: References are aliases for existing variables ✓
|
||||
- D: References cannot be NULL ✓
|
||||
- **Score:** 0/10 (honest assessment!)
|
||||
|
||||
**Why this matters:**
|
||||
- References are fundamental in C++
|
||||
- Used for efficient parameter passing
|
||||
- Critical for understanding modern C++
|
||||
- Different from pointers in important ways
|
||||
|
||||
**Key Concepts to Learn:**
|
||||
1. **Must initialize:** `int& ref = x;` (cannot declare without initialization)
|
||||
2. **Aliases:** Reference is just another name for existing variable
|
||||
3. **Cannot be NULL:** Unlike pointers, references always refer to valid object
|
||||
4. **Cannot reassign:** Once bound to a variable, cannot be changed to refer to another
|
||||
|
||||
**Recommendation:**
|
||||
- **Priority:** HIGH - References are used everywhere in C++
|
||||
- Study C++ Learning Plan: Module 1.6 (Pointers & References)
|
||||
- Practice: Write code comparing pointers vs references
|
||||
- Understand when to use references vs pointers
|
||||
|
||||
**Study Focus:**
|
||||
```cpp
|
||||
// KEY DIFFERENCES TO LEARN:
|
||||
|
||||
// Pointers
|
||||
int* ptr = nullptr; // Can be null
|
||||
ptr = &x; // Can reassign
|
||||
*ptr = 10; // Dereference to use
|
||||
|
||||
// References
|
||||
int& ref = x; // MUST initialize, cannot be null
|
||||
ref = 10; // Direct use (no dereference)
|
||||
// ref = y; // This assigns y's VALUE to x, doesn't rebind ref!
|
||||
```
|
||||

## 📚 Specific Study Recommendations
|
||||
|
||||
### Must Study (High Priority)
|
||||
|
||||
#### References Deep Dive
|
||||
**Why:** Scored 0/10, but critical for C++ mastery
|
||||
**Resources:**
|
||||
- C++ Learning Plan: Module 1.6 sections on references
|
||||
- learncpp.com: Chapter on References
|
||||
- "C++ Primer" Chapter on References vs Pointers
|
||||
|
||||
**Key Learning Points:**
|
||||
1. References must be initialized at declaration
|
||||
2. References are aliases (another name for existing variable)
|
||||
3. References cannot be NULL (unlike pointers)
|
||||
4. References cannot be rebound (unlike pointers)
|
||||
5. Use references for: function parameters, return values, range-based for
|
||||
|
||||
**Practice Questions:**
|
||||
```cpp
|
||||
// What's wrong with these?
|
||||
int& ref; // Error: must initialize
|
||||
int& ref = nullptr; // Error: cannot be null
|
||||
int& ref = 5; // Error: must bind to lvalue
|
||||
|
||||
// What's correct?
|
||||
int x = 10;
|
||||
int& ref = x; // ✓ Correct
|
||||
ref = 20; // What's x now? (Answer: 20)
|
||||
|
||||
// Difference from pointers?
|
||||
int* ptr = &x; // Pointer to x
|
||||
*ptr = 30; // x is now 30
|
||||
ptr = &y; // Can point to different variable
|
||||
|
||||
int& ref2 = x; // Reference to x
|
||||
ref2 = 30; // x is now 30
|
||||
ref2 = y; // This assigns y's VALUE to x! Doesn't rebind!
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Should Review (Medium Priority)
|
||||
|
||||
#### C++ vs Other Languages Type System
|
||||
**Why:** Confused `bool` with `boolean` (lost 3.33 points)
|
||||
**Quick Fix:**
|
||||
|
||||
**C++ Type Keywords:**
|
||||
- `bool` (NOT boolean) - true/false
|
||||
- `int` - integers
|
||||
- `float`, `double` - floating point
|
||||
- `char` - single character
|
||||
- `void` - no type
|
||||
|
||||
**Common Mistakes from Other Languages:**
|
||||
- Java/JavaScript: `boolean` → C++: `bool`
|
||||
- Python: no type keywords → C++: explicit types
|
||||
- JavaScript: `let/const/var` → C++: `int/float/etc`
|
||||

|
||||
while(i < j){
|
||||
while(i < j && s[i] == ' ') i++;
|
||||
while(i < j && s[j] == ' ') j--;
|
||||
if(i >= j) return true;
|
||||
if(s[i] != s[j]) return false;
|
||||
i++;
|
||||
j--;
|
||||
}
|
||||
return true;
|
||||
}

||||
❌ **Not Attempted:** No code submitted
|
||||
|
||||
**Required Implementation:**
|
||||
```cpp
|
||||
class Vector2D {
|
||||
private:
|
||||
double x, y;
|
||||
public:
|
||||
Vector2D(double x, double y) : x(x), y(y) {}
|
||||
|
||||
Vector2D operator+(const Vector2D& other) const {
|
||||
return Vector2D(x + other.x, y + other.y);
|
||||
}
|
||||
|
||||
double operator*(const Vector2D& other) const {
|
||||
return x * other.x + y * other.y;
|
||||
}
|
||||
|
||||
double magnitude() const {
|
||||
return sqrt(x * x + y * y);
|
||||
}
|
||||
|
||||
Vector2D normalize() const {
|
||||
double mag = magnitude();
|
||||
return Vector2D(x / mag, y / mag);
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
**Score:** 0/30 points
|
||||
**Comments:**
|
||||
> This was the most challenging question requiring class design and operator overloading. The Vector2D class needed: Constructor with x, y parameters, operator+ for vector addition, operator* for dot product, magnitude() method using sqrt(x² + y²), normalize() method returning unit vector. This is a significant portion of the exam (30 points). Consider practicing operator overloading and class design before retaking.

# C++ Intermediate Exam Assessment (Latest Attempt)
|
||||
|
||||
Attempt ID: attempt-20251022-110557
|
||||
Submitted: 2025-10-22 11:17:27Z
|
||||
Score: 68 / 110 (61.82%) — NOT PASSED (Required: 70%)
|
||||
|
||||
## Breakdown
|
||||
- Theory: 30/35
|
||||
- Q1: 10/10 — Correct (final keyword)
|
||||
- Q2: 10/15 — Selected A,B,C,D; D is incorrect. Partial credit
|
||||
- Q3: 10/10 — Correct (pure virtual not implemented in base class)
|
||||
- Coding: 38/75
|
||||
- Q4: 20/20 — Correct recursion, proper return type
|
||||
- Q5: 10/25 — Case handling incorrect; index bug
|
||||
- Q6: 8/30 — Typo and API/const-correctness issues
|
||||
|
||||
## Strengths
|
||||
- Strong theoretical understanding of modern C++ OOP concepts
|
||||
- Correct recursive thinking (Q4)
|
||||
- Good grasp of palindrome two-pointer structure
|
||||
|
||||
## Weaknesses / Issues Found
|
||||
- Rule of Five detail: default constructor is not part of the five
|
||||
- Q5: Case normalization and index correctness
|
||||
- j must start at size()-1
|
||||
- std::string has no lower(); use std::tolower on characters (cast to unsigned char)
|
||||
- Q6: Class design and operators
|
||||
- Typo: dobule
|
||||
- Use initializer-list ctor; const correctness on operators
|
||||
- operator+ and operator* should take const Vector2D& and be const
|
||||
- normalize() should handle zero magnitude
|
||||
|
||||
## Targeted Fixes
|
||||
- Q5: Implement case-insensitive compare:
|
||||
```cpp
|
||||
bool isPalindrome(std::string s) {
|
||||
int i = 0, j = static_cast<int>(s.size()) - 1;
|
||||
auto lower = [](unsigned char c){ return std::tolower(c); };
|
||||
while (i < j) {
|
||||
while (i < j && s[i] == ' ') ++i;
|
||||
while (i < j && s[j] == ' ') --j;
|
||||
if (i >= j) return true;
|
||||
if (lower((unsigned char)s[i]) != lower((unsigned char)s[j])) return false;
|
||||
++i; --j;
|
||||
}
|
||||
return true;
|
||||
}
|
||||
```
|
||||
- Q6: Revised Vector2D
|
||||
```cpp
|
||||
class Vector2D {
|
||||
double x, y;
|
||||
public:
|
||||
Vector2D(double x, double y) : x(x), y(y) {}
|
||||
Vector2D operator+(const Vector2D& o) const { return {x + o.x, y + o.y}; }
|
||||
double operator*(const Vector2D& o) const { return x * o.x + y * o.y; }
|
||||
double magnitude() const { return std::sqrt(x*x + y*y); }
|
||||
Vector2D normalize() const {
|
||||
double m = magnitude();
|
||||
return (m > 0) ? Vector2D(x/m, y/m) : Vector2D(0, 0);
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
## Next Steps (2 weeks)
|
||||
1. Revisit Rule of Five specifics (what are the five, when to define)
|
||||
2. Practice string normalization and validation patterns
|
||||
3. Implement 3 small classes with operators (Point2D, Fraction, Complex)
|
||||
4. Retake the intermediate exam after fixes; target ≥ 80%
|
||||
