2. Body mass index (BMI) is an indirect measure of a person's body fat. In St units (metric system) BMI is defined as the weight in kilograms divided by height in meters squared BMI = (weight (kg) / [height (m)]?). A person with a BMI above 22.9 is considered overweight. A person with a BMI under 18.5 is considered underweight. Write a complete C program that reads the weight of a person from standard input (keyboard) and height of a person then prints the BMI to standard output (screen). The program also writes the category of person to the screen based on the BMI index and the following table. Category Underweight Normal Range Overweight - At Risk Overweight - Moderately Obese Overweight - Severely Obese BMI range - kg/m
