# S-Lang Cheatsheet ## Overview - Interpreted programming language - C-like syntax - Dynamic typing - Supports both procedural and object-oriented programming - Comes with a standard library of useful functions ## Variables - Variables are dynamically typed - Declaration not required - Naming conventions: - Must start with a letter or underscore - Can contain letters, digits, and underscores - Examples: ``` x = 5 str = "hello" b = true ``` ## Functions - Can take any number of arguments - Can return any type - Arguments are passed by value - Examples: ``` function add(x, y) { return x + y } function print(str) { printf("%s\n", str) } ``` ## Loops - Supports while and for loops - Examples: ``` while (x < 10) { x = x + 1 } for (i = 0; i < 10; i++) { print(i) } ``` ## Conditionals - Supports if-else statements - Examples: ``` if (x < 5) { print("x is less than 5") } else { print("x is greater than or equal to 5") } ``` ## File manipulation - Supports reading and writing to files - Examples: ``` f = fopen("file.txt", "r") line = fgets(f) fclose(f) ``` ``` f = fopen("file.txt", "w") fprintf(f, "hello\n") fclose(f) ``` ## Resources - [S-Lang Programming Language](https://www.jedsoft.org/slang/) - [S-Lang Programming Language Wiki](https://github.com/jedburke/slang/wiki) - [S-Lang Examples](https://github.com/jedburke/slang/tree/master/examples)
