C++

Read floating-point numbers from input until a floating-point number is read that is not in the range 15.0 to 25.0, both exclusive. For each floating-point number read that is in the given range, output the floating-point number followed by " is valid". Then, output the floating-point number read that causes the reading to stop followed by " is invalid". End each output with a newline. Ex: If the input is 8.120.314.510.0, then the output is: 8.1 is valid 20.3 is invalid
