Addition of Two Numbers
Adding two numbers in programming is essentially the same as adding two numbers in general arithmetic. A significant difference is that in programming, you need to pay attention to the data type of the variable that will hold the sum of two numbers.
C++
C++ is a general-purpose hybrid language, which supports both OOPs and procedural language designed and developed by Bjarne Stroustrup. It began in 1979 as “C with Classes” at Bell Labs and first appeared in the year 1985 as C++. It is the superset of C programming language, because it uses most of the C code syntax. Due to its hybrid functionality, it used to develop embedded systems, operating systems, web browser, GUI and video games.

- Create a java program that will ask the weight (kg) and height (cm) of the user, the program will calculate and display the user's BMI status. If the BMI of a person is greater than or equal to 30, display “Obese”, if the BMI greater than or equal to 25, display “Overweight”, and if the BMI is greater than or equal to 18.5, display “Normal”, else display “Underweight”. Follow the format below.Program must be in Java Body Mass Index (BMI) is one of the criteria that is used to calculate whether one is fit or not basing on a person’s height (m) and weight (kg). The criterion is very simple; if one’s BMI is 25 or greater, it signifies overweight. A BMI less or equal to 18.5 indicates underweight. Lastly, a BMI greater than 30 shows obesity.You have been requested to create a program that that helps the Namibian Defence Forces’ (NDF) Captain to calculates the BMI of a person (BMI = weight/height2) and also determine whether the person has also completed running 10 km in the required time.
