Article Introduction：C++ templates provide type safety, code reuse and generalization, but will result in compile time overhead and code bloat; macros are easy to use and have low overhead, but have the disadvantages of insecurity, code opacity and lack of generalization. Templates are suitable for common code that requires compile-time type checking and generalization, such as sorting algorithms; macros are suitable for operations that require low overhead and simple text replacement, such as recording function execution times.

Article Introduction：Introduction to PHP: PHP is an open source web development scripting language. PHP syntax is simple and suitable for beginners. Basic syntax: Use tags to represent PHP code. Variables start with a $ symbol (example: $username). Data types include strings, numbers, floats, booleans, and arrays. Conditional statements (such as if) control the flow of code based on conditions. Loops (such as for) allow blocks of code to be executed repeatedly. PHP supports connections to databases such as MySQL. Practical example: Create a PHP script that displays "Hello, World!" and the current time.

Article Introduction：I'm making a simple hangman game with go but I'm running into a bug where the unknown_string string (which will be shown in the code) has _ characters so other players guessing the letters can see the length of the word and whenever the player types correctly of a letter, I want it to replace the nth (n depends on the index where the letter is found in the word) _ character with that letter, this has been successful, but there is a problem. If a word has two repeated letters, only one of them is replaced. I created a separate function called iterate (this function is because I want to avoid nested code) to iterate over all indexes.
