Compound Interest Calculator - Xiao-XC/C-Practice-Projects GitHub Wiki
Compound-Interest-Calculator
Type: Bro Code course project
Date: Sept 2026
Concepts: mixed double/int input, percent-to-decimal conversion, pow(), escaping % in printf
What it does
Calculates the future value of an investment from a principal, interest rate, number of years, and compounding frequency.
What I learned
A lone % in a printf format string is invalid because % starts a format specifier, so a literal percent sign has to be written %%. I debugged and fixed this myself after it was flagged.
