Think hard about how to do this. If your input is the following string: “12345.9876” what do you have to do to each character in the string to generate your float? How are the numbers before the decimal point different to the numbers after the decimal point? Make sure you have an algorithm that works correctly on paper before you start coding and draw a state transition diagram for the scanning part of your lexer. i noticed on the website you guys have code snippets so can some point me into the right dirrect of code or if some has already answer this question plz show their post so that i can get an idea
