Topic 13 of 13 in C++ — Complete Tutorial (Beginner) — 5 lessons.

Simple Calculator

This project builds a calculate function that takes two numbers and an operator, using a switch and throwing on division by zero — combining functions, switch, and exceptions.

Grade Reporter

This project uses a Student class and a vector to compute averages and grades, then prints a report — combining classes, containers, loops, and methods.

Number Guessing Game

This project processes a vector of guesses in a loop using a function, conditionals, and break — the core logic of a guessing game.
