C language realizes the effect of mine sweeping + demining during demining

My first blog (focusing on the effect of spreading out when demining that I achieved) 1. Start the game: print a menu to prompt the user for input (the function is just packaged code and has no return value) void Menu() { printf(“******************\ “); printf(“****1: Play Minesweeper****\ “); printf(“****0:Exit Minesweeper****\ “); printf(“******************\ “); } Define […]

Typescript generics, keyof, typeof, index type, mapping

Typescript generics A major part of software engineering is building components that not only have well-defined and consistent APIs, but are also reusable. Components that can handle today’s and tomorrow’s data will give you the most flexible ability to build large software systems. Use generic type variables function identity<Type>(arg: Type): Type { return arg; } […]
