Learn how the earliest relationships with caregivers can promote healthy brain development, how young children build social and emotional skills, and ways you can support language and literacy development starting from birth. Getting Started Overview. Get started with the Fitbit Software Development Kit (SDK), you can quickly create apps and clock faces for Fitbit OS 5 devices, such as Fitbit Versa 3 and Fitbit Sense, or older Fitbit OS 4 devices, such as Fitbit Ionic, Versa, Versa Lite, and Versa 2. What You’ll Need. Before you get started, you'll need the following prerequisites to develop apps or clock faces.
About Us
Focused on creating a North American cobalt supply chain.
First Cobalt is a North American cobalt company and owner of the only permitted primary cobalt refinery in North America. The Company is exploring a restart of the First Cobalt Refinery in Ontario, Canada, which could produce over 25,000 tonnes of cobalt sulfate per year from third party feed. First Cobalt’s main cobalt exploration project is the Iron Creek Cobalt Project in Idaho, USA, which has an Indicated Resource of 2.2 million tonnes at 0.32% cobalt equivalent (0.26% cobalt and 0.61% copper) for 12.3 million pounds of contained cobalt and 29 million pounds of contained copper as well as an Inferred Resource of 2.7 million tonnes at 0.28% cobalt equivalent (0.22% cobalt and 0.68% copper) for an additional 12.7 million pounds of contained cobalt and 40 million pounds of contained copper. The Company also controls a significant land package in the Canadian Cobalt Camp spanning over 100 km2, which contains more than 50 past producing mines.

Before we study the basic building blocks of the C programming language, let us look at a bare minimum C program structure so that we can take it as a reference in the upcoming chapters.
Hello World Example
A C program basically consists of the following parts −
- Preprocessor Commands
- Functions
- Variables
- Statements & Expressions
- Comments
Let us look at a simple code that would print the words 'Hello World' −

Let us take a look at the various parts of the above program −
The first line of the program #include <stdio.h> is a preprocessor command, which tells a C compiler to include stdio.h file before going to actual compilation.
The next line int main() is the main function where the program execution begins.
The next line /*...*/ will be ignored by the compiler and it has been put to add additional comments in the program. So such lines are called comments in the program.
The next line printf(...) is another function available in C which causes the message 'Hello, World!' to be displayed on the screen.
The next line return 0; terminates the main() function and returns the value 0.
Compile and Execute C Program
Let us see how to save the source code in a file, and how to compile and run it. Following are the simple steps −
Open a text editor and add the above-mentioned code.
Save the file as hello.c
Open a command prompt and go to the directory where you have saved the file.
Type gcc hello.c and press enter to compile your code.
If there are no errors in your code, the command prompt will take you to the next line and would generate a.out executable file.
Now, type a.out to execute your program.
You will see the output 'Hello World' printed on the screen.

Make sure the gcc compiler is in your path and that you are running it in the directory containing the source file hello.c.
