Lambda Examples (Runnable C++ files)

This folder contains simple, runnable C++ example programs that accompany the lambda.md tutorial.

Example Source Files and Purpose

• test_main.cpp test_main.cpp - demonstrate syntax uses of lambda function
• sort_by_length.cpp sort_by_length.cpp — sort strings by length using a lambda comparator.
• transform_squares.cpp transform_squares.cpp — use std::transform with a generic lambda to compute squares.
• move_capture_thread.cpp move_capture_thread.cpp — demonstrate move-capture of std::unique_ptr into a lambda used by std::thread.
• counter_lambda.cpp counter_lambda.cpp — a function returning a lambda that keeps an internal counter (closure state).

Build & Run (Linux / macOS / WSL)

Compile each example with g++ (GNU C++ compiler) and run:

g++ -std=c++17 test_main.cpp -o test_main
./test_main

g++ -std=c++17 sort_by_length.cpp -o sort_by_length
./sort_by_length

g++ -std=c++17 transform_squares.cpp -o transform_squares
./transform_squares

g++ -std=c++17 move_capture_thread.cpp -pthread -o move_capture_thread
./move_capture_thread

g++ -std=c++17 counter_lambda.cpp -o counter_lambda
./counter_lambda

Notes:

• For move_capture_thread.cpp you need to link with pthread (-pthread).
• All examples use modern C++ and should compile with -std=c++17 or later.
