C and C++ are very powerful programming languages. They are especially popular among embedded developers because it allows us to get fine control over memory usage while maintaining high speed. Open up VScode, File > New File > .cpp and then make a new file called HelloWorld.cpp. Copy/paste the following code.
#include <iostream>
int main() {
std::cout << "Hello World!";
return 0;
}This code creates a function called main. It then uses the std(stands for: standard) function cout(stands for: character output) to print out the string "Hello World".
To run this code go to the top menu bar. Terminal > New Terminal. A new terminal window should open from the bottom of the screen. In the terminal type g++ HelloWorld.cpp -o haha.exe This line compiles the file HelloWorld.cpp and makes it into an executable file called haha.exe. The convention is to make the file name and exe name the same, but this shows that it doesn't have to be the same. To run the code, type ./haha.exe into the terminal. You should see Hello World pop up in the terminal.
Good job, you made your first C++ program
A variable is a name given to a memory location, which you can use to store information. C++ is a strongly typed language, which means you have to specify the data type of a variable, this article gives a list of the primitive types in C++. The most often used ones include bool(boolean: true or false), int (integer), and double(double precision decimal number). Notably, string is not in this list because it is a data type from the standard library(std).
Try storing your faviorate number into a double variable and print it out.
