Computers are really, really, strictly stupid. For example, "Double" is not the same as "double". Hence the error.

Likewise, "feet" and "inches" were never declared with something like int feet; or double feet;.

Line 33 is trying to declare another variable named "BMI" with a different type (double instead of int). The first is already declared on line 12. Pick one. (Remove the other.)

Remember, it is okay to declare a variable in one spot and simply assign to it in another spot.

double BMI;
...
BMI = adjusted_weight / HeightSq;

You should, however, get into the habit of keeping declaration and assignment as close together as possible. In this case, you could just get rid of the declaration at the top and do everything on line 33:

double BMI = adjusted_weight / HeightSq;

The remaining errors (illegal << stuff) start with a syntax error on line 35, where you started writing an output statement and didn't finish.

Remember to use your compiler's error messages to help you figure out what you typed wrong. Those of us who have been doing this for ages are very good at looking at those messages and fixing our typos and brain farts.

Hope this helps.

Hello Gspiller81,

The only things I can add to what Duthomhas has started with is:

PLEASE ALWAYS USE CODE TAGS (the <> formatting button), to the right of this box, when posting code.

Along with the proper indenting it makes it easier to read your code and also easier to respond to your post.

http://www.cplusplus.com/articles/jEywvCM9/
http://www.cplusplus.com/articles/z13hAqkS/

Hint: You can edit your post, highlight your code and press the <> formatting button.

You can use the preview button at the bottom to see how it looks.

I found the second link to be the most help.

When writing your code compile often and fix your mistakes as you go and not all at one time when you are finished.

Andy
