Is there any chance that treehouse will provide C programming language courses soon enough?

Treehouse won't be teaching "C".

If you search the forum history, you'll find this question has been asked many times before, and sometimes answered by the staff. Here's the gist of those responses:

While languages like "C" and "C++" are certainly popular, they tend to be used for things other than the web technologies which are the focus of Treehouse.

Nafis Fuad I believe C and C++ are low level languages which are complex to learn and only now a days used to build complex stuff like a whole new operating system. But for app dev and web dev and even game dev, you can do so by using a more simple high level language; example ruby and python

Hello world written in C++

#include <iostream>

int main()
{
    std::cout << "Hello world!\n";
    return 0;
}

Hello world written in python

print("Hello world.")

Hello world written in ruby

puts "Hello World."

Thank you, guys.
