## README

# Implements the function of invoking the C standard library using NAPI

## Introduction

This codelab describes how to use DevEco Studio to create a native C++ app and call the C standard library to calculate the square root of the sum of squares of two given numbers. The following figure shows the effect.

## Concepts

- Native Development Kit (NDK): a collection of native APIs, compilation scripts, and compilation toolchains provided by the HarmonyOS SDK. It helps you implement key app functions using the C or C++ language.
- Standard libraries: C library, C++ library, OpenSL ES, and zlib.
