I am in touch with C and C++ from 3 years,and have good theory knowledge of these language.
In both language i have done some practical problems . I also participated in competitive coding with these languages.
So i will be able to help in writing content with proper examples.
e.g. In C pointer ,structure are key topics . So i can give u good and explain clearly those concepts.
Also for C++ i can give you OOPS concept with proper explaination.
