You don't write programs in a class in C++, you write programs that use classes. Every C++ has at least one function, main, the entry point of the application. You define the classes and functions that are used by your main function. Classes allow you to classify the objects used by your program, allowing data to be manipulated in a highly controlled manner, ensuring consistency and robustness throughout your program.
