#Csce 550 Principles Of Programming Languages
Church numerals are a way of representing natural numbers using lambda calculus. a foundational framework in mathematical logic and computer science. In essence
Redex is a deducible expression. It is a lambda abstraction applied to an argumentReduction replaces a redex with the result of applying the function.Beta Reduc
A formal system used to study functions, variables & how they interact through application & abstraction. It's a foundational mathematical framework tha
A type environment (T) maps variables names to theirs types. For example:+ is mapped to the type , Int -> Int -> Int y is mapped to the type Int Lambda E
In type theory, sub typing denoted by (<:) is a relation that describes when one type can be used in place of another type. It's more like flexible version o
Solve each of the following constraints. Let's first understand the tools to solve it:Constraint Solving in type inference involves finding a way to make d
How to solve it?Let's learn.A type environment (T) maps variables names to theirs types. For example:+ is mapped to the type , Int -> Int -> Int y is map
Static TypingDefinition: In statically typed languages, type checking is done at compile time. This means that the types of all variables must be known before t
To explain the concepts of soundness and completeness, particularly in the context of type checking and type inference, we can use analogies to make them easier
1. Ad-hoc Polymorphism Function or operator overloading based on different typesint add(int a, int b) { return a + b; } double add(double a, d
What is Rust?Rust is a system programming language that focuses on speed, memory safety, and parallelism. It was developed by Mozilla and has been gaining popul
Findings from the study on borrow patterns within Rust's open-source ecosystem.The purpose of the study:This study aims to analyse how the borrow checker is uti
Let's look at how memory is managed in multiple languages first.Imagine you're renting bikes from a shop:C/C++: Manual Memory ManagementYou have to manually pi
