When invented C++ was a C fork called “C with classes“. The idea behind was to “borrow” from Simula.
And the Simula (Algol) idea is to design and write abstractions that will solve the requirements.
The idea behind C is to design and write a program that will solve the requirements. Preferably not in assembler.
Do you see the difference?
After several decades have passed, one might think it is safe to conclude, the C idea has prevailed.
