Assignment Description:
Write a program that calculate the Body Mass Index (BMI). Your program should perform the following tasks:
Prompt the user to enter the following data for each person:
? ID (four digit integer),
? Name 20 character string,
? Weight in pounds (floating-point with 1 digit after decimal point),
? Height in inches (floating-point with 1 digit after decimal point).
ComputetheBMIusingthefollowingformula:
BMI = (weightInPounds * 703) / (heightInInches * heightInInches)
Save (Write) the input data (id, name, weight, height) and the calculated BMI (floating-point with 2 digits after decimal point) into a text file (e.g. bmifile.txt).
Repeat steps 1-3 to compute the BMIs for three persons, then close the text file.
Program Requirements:
The program must use streams, cout and cin objects to perform the IOs with
console, printer, and file, and use IO manipulators to format the output.
The program should include the following information as comment on top of source
code:
? Programming assignment number
? Author of the program
? Date of programming (or due date)
? Brief description on what the program will do
