C++ Code Snippets (By Ali Imran)

Tired of typing common C++ boilerplate and repetitive code structures? This VS Code extension provides a comprehensive collection of essential C++ code snippets designed to boost your productivity in competitive programming, general development, and daily coding tasks. Spend less time writing boilerplate and more time solving problems!

✨ Features

This extension provides a rich set of snippets for various C++ programming needs:

🚀 Competitive Programming Kickstart

Get ready for competitive programming challenges in an instant.

  • Boilerplate (Prefix: boilerplate_comp): Inserts a full competitive programming setup, including a wide range of standard headers, common using declarations, fast I/O macros, and type aliases.
    // Example output for 'boilerplate_comp'
    #include <iostream>
    #include <string>
    // ... many more includes ...
    using namespace std;
    using ll = long long;
    #define fastc ios::sync_with_stdio(false); cin.tie(nullptr);
    #define endl '\n'
    
    int main(){
        fastc;
        cout<<"I'm Coconut"<<endl; // Or your default main content
        return 0;
    }
    
  • Basic Boilerplate (Prefix: boilerplate): A simpler "Hello, World!" boilerplate for quick starts.
    // Example output for 'boilerplate'
    #include <iostream>
    using namespace std;
    
    int main() {
        cout << "Hello, World!" << endl;
        return 0;
    }
    
  • Main Function (Prefix: main): Inserts a standard int main() {} structure.
    // Example output for 'main'
    int main() {
        // Your code here
        return 0;
    }
    

💬 Smart cout Statements

Streamline your output with multi-variable cout snippets.

  • cout (Prefix: cout): cout << variable << endl;
  • cout2 (Prefix: cout2): cout << var1 << var2 << endl;
  • cout3 (Prefix: cout3): cout << var1 << var2 << var3 << endl;
  • cout4 (Prefix: cout4): cout << var1 << var2 << var3 << var4 << endl;
  • cout5 (Prefix: cout5): cout << var1 << var2 << var3 << var4 << var5 << endl;

    Usage Tip: Type cout then Tab, fill in the variable. For multiple variables, append the number, e.g., cout3 and hit Tab to navigate through placeholders.

🔢 Control Flow & Structures

Quickly generate common C++ constructs.

  • Integer For Loop (Prefix: fori): A standard for (int i = 0; i < n; ++i) {} loop.
  • Class Template (Prefix: class): Inserts a basic C++ class definition with constructor and destructor placeholders.
  • Scoped Enum (Prefix: enum_class): Defines a type-safe enum class.
  • Try-Catch Block (Prefix: tryc): Inserts a try-catch block for exception handling.
  • Lambda Function (Prefix: lambda): A versatile template for C++ lambda expressions.

📊 Vector Utilities

Efficiently work with std::vectors.

  • Declare Vector (Prefix: vec): vector<int> name;
  • Declare Vector with Size (Prefix: vecs): vector<int> name(size);
  • Declare Vector with Size & Value (Prefix: vecsv): vector<int> name(size, value);
  • 2D Vector (Prefix: vec2d): vector<vector<int>> name(rows, vector<int>(cols, 0));
  • Vector For Loop (Index) (Prefix: vfor): Iterate using an index-based for loop.
  • Vector For Loop (Range) (Prefix: vforr): Iterate using a range-based for loop.
  • Sort Vector (Prefix: sortv): sort(vec.begin(), vec.end());
  • Reverse Vector (Prefix: reversev): reverse(vec.begin(), vec.end());

🐛 Debugging Aid

Simplify adding debug print statements.

  • Debug Print (Prefix: dbg): Inserts cerr << "DEBUG: var_name = " << var_name << endl;

🚀 Installation

  1. Open VS Code.
  2. Go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X).
  3. Search for "C++ Code Snippets" (or cpp-code-snippets).
  4. Click "Install".

🛠️ Requirements

  • Visual Studio Code (version 1.101.0 or higher, as per your package.json).
  • A C++ extension like "C/C++ Extension Pack" by Microsoft is recommended for full language support and IntelliSense, though snippets will work independently.
