Model-View-Controller (MVC) is one of the most common design patterns used to develop applications with graphical user interfaces (GUI), especially in object-oriented programming languages.

I summarize here three initial works on MVC from 1970s and 1980s along with my comments.

These are my notes taken while reading chapter 7 “Functions” from the book “Modern C” by Jens Gustedt.

This chapter discusses structuring C program using functions; particularly, attention is given to recursion, that is, to the ability of C functions to invoke themselves.

These are my notes taken while reading chapter 6 “Derived data types” from the book “Modern C” by Jens Gustedt.

This chapter discusses objects that consist of other objects, such as arrays, pointers, structures, and type aliases.

Whenever a computer program needs to store data of the size determined only during the runtime, then dynamic memory allocation is required. Memory allocation happens in the memory heap, and in C is commonly done via a library function malloc, which has subtle things with its usage that I would like to discuss here.

These are my notes taken while reading chapter 5 “Basic values and data” from the book “Modern C” by Jens Gustedt.

This chapter discusses values of different objects that are used in a C program, and how they are represented.

I’d like to share some knowledge about subtle thing that I have learned recently in C. It is related to the relations between arrays and pointers, and how they are often treated as equivalent to each other (for example, this is how passing an array to a function works when one of the expected arguments is a pointer). However, arrays and pointers are not equivalent to each other.

These are my notes taken while reading chapter 4 “Expressing computations” from the book “Modern C” by Jens Gustedt.

This chapter discusses expressions, that is, computations based on some values, such as variables and literals.

These are my notes taken while reading chapter 3 “Everything is about control” from the book “Modern C” by Jens Gustedt. This chapter explains five control block statements: conditional statements with if, loops with for, while, and do-while, and selection statements with switch.

These are my notes taken while reading the preamble for the part “Level 1. Aquaintance” from the book “Modern C” by Jens Gustedt. This preamble introduces stylistic decisions that the author uses in the rest of the book.
