This document describes 8 programs to study basic C++ concepts including determining leap years, finding the maximum number, calculating circumference and area using radius, calculating salary increases based on grade, decrementing salary, identifying vowels, performing arithmetic operations, and comparing numbers for equality. The objective is to learn C++ and run programs using the Dev C++ development environment on a personal computer.
