[!TLDR]

Evaluate y = 3x^2 + 4x - 2 for the entered x; x = 2 gives y = 18.00.

This shows how an algebraic expression is translated into a C arithmetic expression. There is no exponent operator in C, so x^2 is written as xx, and normal operator precedence (multiplication before addition/subtraction) means 3xx + 4x - 2 evaluates exactly as the mathematics intends. The program reads x, computes y, and prints it to two decimal places. …
