Floating Point

FloatingPoint /* This program demonstrates use of floating-point numbers * * It performs the following: * 1. reads two FP numbers from the Terminal window * 2. performs +, -, *, and / on the numbers * 3. prints the results on the Terminal window * Note: Please enable "Echo input" in the terminal window */ #include <stdio.h>
