1. Construct a program that will ask the user the current date and his/her birthday and display the number of days
they have been alive. You can ignore leap years.

I have little experience in MATLAB or programming in general, but a little help to get me started would be appreciated. Thanks

Welcome to the PF.

How many days are there in each month? (Hint -- you will need to list each month)

How many days are there in each (non-leap) year?

What can you do with those sets of numbers, given their birthdate and current date, to find out how many days they've been alive.

Show us some initial work (can just be pseudo-code for now)...

I apologize for the absence of an attempt, but I don't even know what syntax to use or where to start. I've never programmed before and this is my first programming class for engineering. My professor said he would show us but I wanted to struggle a little bit first.

In addition to the MATLAB resources that Mark44 pointed you to, often in programming, we do a first pass in "pseudocode" or just plain words to map out what we want the program to do. You don't need to dive straight into coding in C or Java or MATLAB or whatever. It helps you to stand back and see what the overall flow of the program should be.

So can you take a cut at what the program should do overall?

Like,

** Prompt & User inputs today's date in MM/DD/YYYY (or whatever) format

** Prompt & User inputs a birthdate in MM/DD/YYYY (or whatever) format

** Count up the number of days between the two dates

** Output the answer

Now, can you think of some ways to help you count up the number of days between the two dates? There are several ways you could do it, and some of them are eaiser to code up in a program than others. Maybe sketch out some examples for yourself to start to get an idea of what constant numbers you might want to define in your program, and how you might like to do the math of the date subtraction...

BTW, Quiz Question for you:

Why did I suggest MM/DD/YYYY format for the dates, instead of MM/DD/YY format?
