Any good recommendations to learn more about pointers especially to understand the terminology (heap, stack etc)?

Answer 1

Learning by doing is the best way for understanding how pointers work. Just use the code playground of SOLOLEARN and create some pointers containing references of variables and try to understand the accessibility of variables and pointers. As a suggestion for better understanding of heap and stack i can recommend you this link:
