Also, what do you mean by set maxHeight to -1000; ?

**C Programming**

Ok, I changed all my floats to double floats and changed my scanfs to read in double floats. I'm looking at the code you posted and I have a question. What would go into "time"? Like when you say time=staringtime; time<=endingtime; Declare additional variables...

**C Programming**

I remember my instructor telling us that we couldn't use a for loop to create the table because for loops must use integers, and for us to use a while loop since the starting time, time increment, and ending time are floating point numbers, and not integers.

I don't know what to do now. Below is my code I have so far but I have no idea what to do next. Here's the prompt for what the program should do: Welcome to the Weather Balloon Altitude and Velocity Program. Enter the Balloon's Starting Time: 1 Enter the Time ...

Ah! Thanks. When I was doing my if and while statements, I kept doing (heading < 0.0 || > 360.0) and kept wondering why it wasn't working. It needs to be while (heading <= 0.0 || heading > 360.0);

**C Programming**

Hmm, code was too long for the post? Here's a second try. /* Directives */ #include <stdio.h> int main(void) { double heading; /*compass heading in degrees*/ /* Get compass heading */ printf("Enter a Compass Heading: "); scanf("%lf", &heading...

**C Programming**

How do you reprompt after the user inputs a wrong number into the program in C Programming? Loop structure? i.e. I want my code to do this: Enter a Compass Heading: 500.7 Please Input a Compass Heading between 0 and 360 Degrees. Enter a Compass Heading: 360.0 If the user puts ...

**C Programming**

Yeah! I keep forgetting to write comments for each part of my code. But I'll make sure I write up good comments for the code.
*September 29, 2009*

**C Programming**

Yes, I have learned the if else statements. I made another switch statement within the first switch statement to account for the F to F and C to C and that did the trick. Thanks.

**C Programming**

MathMate was helping me with it the other day. Everything works correctly except for when I convert it from Celsius to Celsius (same thing), I'm wondering how I would make a code to make it output the same input number since it's going to be the same temperature.
*September 29, 2009*

**C Programming**

Okay, question. What if I inputted this: Enter a temperature: 32 Enter 'C' for Celsius or 'F' for Fahrenheit: c Choose a conversion ('C' for Celsius or 'F' for Fahrenheit): c The temperature is: 0.0 C. I want the program to read [The temperature...

**C Programming**

Yeah, at first I had the formulas in the wrong place, then I put 5/9 in one of the formulas instead of 9/5. Thanks for all your help man. I don't know what I would do without you. THANK YOU!!!
*September 25, 2009*

**C Programming**

Oh! There's my problem. It's 9/5, not 5/9.
*September 25, 2009*

**C Programming**

Hmm, my F to C conversion works fine but my C to F is not giving me the right output. My code for C to F is (temp * 5/9) + 32. I think it's the way you divide the 5/9. Starting out with 32.4, when I do it a certain way on my calculator, I get 50, which the program is ...
*September 25, 2009*

**C Programming**

It doesn't close out the window. It just goes back to the ~> Now I just gotta figure out why my math is wrong since it's not spitting out the correct temperatures after the conversion.

**C Programming**

We have just talked a little bit about loops structures. Haven't gotten into any coding with it though.
*September 25, 2009*

**C Programming**

Nevermind! I found out how to end the program if it's not C,c,f,F after experimenting. return(0); =]
*September 25, 2009*

**C Programming**

Ok, I replaced the second switch with the code you provided earlier and now I got the second switch to operate correctly. I'm just wondering how to end the program if the user does not enter C,c, F, f.
*September 25, 2009*

**C Programming**

Thanks! Now the first switch is working. But how do you end the program if the user inputs something else than C,c,F,f? It displays "Invalid Syntax" but it still moves onto the next line. I want it to just stop at "Invalid Syntax" if the user doesn't ...
*September 25, 2009*

**C Programming**

Okay, so since my first switch statement is useless, how would I go about getting the program to only recognize F, f, C, and c only and if anything else than that is inputted for it to display "Invalid Syntax"?
*September 25, 2009*

**C Programming**

Alright. I think I'm almost there. I'm just having a slight problem when I'm running the program. This is how it should look like (for reference). Enter a temperature: 32.4 Enter 'C' for Celsius or 'F' for Fahrenheit: C Choose a conversion ('C&#...
*September 25, 2009*

**C Programming**

Oh yeah, and I need to use a switch statement in this program. The instructor's orders.
*September 25, 2009*

**C Programming**

I'm guessing the //get char. from keyboard is a comment telling what the code you just wrote means?
*September 25, 2009*

**C Programming**

This is what the program needs to do: Enter a temperature: 32.4 Enter 'C' for Celsius or 'F' for Fahrenheit: C Choose a conversion ('C' for Celsius or 'F' for Fahrenheit): F The temperature is: 90.3 F. How would I store the input when it asks ...
*September 25, 2009*

**C Programming**

Write a program that prompts the user to enter a temperature, followed by a letter representing Celsius (C) or Fahrenheit (F). Then prompt the user for the conversion type and print the results to the screen with one decimal point. If the user enters a letter other than 'C...

find the derivative of f(x)=tanx-4/secx I used the quotient rule and got (sec^2x-4)(secx)-(tanx-4)(cosx)/sec^2x but I'm pretty sure that's wrong. Help. Thanks.

I got the same answer but for some reason, it's not the right answer(webwork). Thanks though!
