Building a Perl Calculator with Conditional Logic

Have you ever wanted to write a practical script in Perl but did not know where to start? Building a calculator is the perfect way to learn how programming languages process user input, perform operations, and return results. This course guides you through the process of writing a fully functional calculator program in Perl, using conditional logic and operator matching. You will transform from a curious beginner into a programmer who understands how to control the flow of an application. Through reading and writing structured code, you will learn how to handle user inputs, process mathematical operators, and display calculated results in the terminal. You will also learn modern Perl practices such as using strict and warnings pragmata, using basic testing strategies to verify your logic, and writing clean, modern syntax. What you will learn: Understand foundational Perl syntax, variables, and basic operators; Handle user inputs from the command line cleanly; Apply conditional logic using if, elsif, and else statements; Match operators to perform addition, subtraction, multiplication, and division; Implement modern Perl code structure and basic error handling. This text-only course starts with the absolute basics of Perl syntax and operator logic before guiding you step-by-step through the calculator script design. This course is designed specifically for beginners with no prior programming experience. Start reading today to write your first functional Perl program.
