so i have this project for school to create a pascal program. i was thinking of making a calculator which can do stuff like cosine and all that stuff. like a scientific calculator. The program has to use crt because thats all weve learnt so far. im not an expert at pascal but i still understand some stuff like loops and menus and such. would the only way to make this be a menu saying stuff like 1) Plus, 2) Minus and so on? or is it possible to just enter in a whole line like 1+4 and then you get the answer? all i want is the basic layout of the program to start off with and then i can build it up.
