help a noob...

ya... i'm a complete noob to c++ (or any other language for that matter)
One of my friends bought me c++ for dummies as a joke, but it ended up being helpful (well enough for me to get a fair start...).

i got the compiler (dev-c++ v4.9.8.0 i think) i typed a whole [simple] code, clicked compile and it doesn't compile. Instead it goes to a new tab with a different code with a highlighted line etc. [i know don't know much about what i'm doing atm]

plz help (will update with pics and stuff later, when i'm not in a hotel -.-)

 

Post your exact code.

When you get a compile error your description is what happens. You will generally get a highlighted line, with a listbox (or other) outlining your errors at some place in the window.

A runtime error is something that is "correct" by the compiler checker, but is thrown due to bad programming logic. For example, a NullPointerException means that you are trying to use a null value (often caused by not assigning variables values, etc.) in place of something else (sorry about my bad description, but I have not studied in a long time, so I forgot how many things work).

 

ok im back at my house and heres my problems...

conversion code... from celsius to fahrenheit

Code:

 
//
//  Program to convert temperature from Celsius degree 
//  units into Fahrenheit degree units:
//  Fahrenheit = Celsius  * (212 - 32)/100 + 32
//
#include <cstdio>
#include <cstdlib>
#include <iostream>
using namespace std;
int main(int nNumberofArgs, char* pszArgs[])
{
  // enter the temperature in Celsius
  int celcius;
  cout << "Enter the temperature in Celsius:";
  cin >>> celsius;
  // calculate conversion factor for Celsius
  // to Fahrenheit
  int Fahrenheit = factor * celsius/100 + 32; 
  // output the results (followed by a NewLine)
  cout << "Fahrenheit value is:";
  cout << fahrenheit << endl;
  //wait until user is ready before terminating program
  //to allow the user to see the program results
  system("PAUSE");
  return 0;
}

after i click compile>>>

i'm fairly new to sythe so if i did something wrong plz let me know =/

as you can see... i have no idea what im doing (learning)

 

Here is the fixed working code, there were quite a few problems with yours so I almost completely re-worked it. Feel free to ask questions even though I'm no C++ guru.

Code:

#include <iostream>

using namespace std;

int main()
{
  // Declare both of our variables as floating point
  double Celsius;
  double Fahrenheit;
  // Ask for user to input temperature in Celsius
  cout << "Enter the temperature in Celsius: ";
  // Get the temperature imput by the user
  cin >> Celsius;
  // Convert the user's temperature from Celsius to Fahrenheit
  Fahrenheit = 1.8 * Celsius + 32; 
  // Output the resulting temperature in Fahrenheit followed by a new line
  cout << "Fahrenheit value is: ";
  cout << Fahrenheit << endl;
  // Pause the program until the user is ready so he/she may view the result
  system("PAUSE");
  return 0;
}

 

its not the script thats the problem, its the compiler...it goes to the second code i pasted after i click compile.

i don't know what I'm doing... is there some settings i need to change before i can use it?

 

Of course, it's also the script that's the problem. I corrected 5+ errors while re-making it.

Just get Dev-C++ from Bloodshed anyway. http://www.bloodshed.net/download.html

 

thanks ... now its working

 

Which is why the Microsoft C(++) compiler /fails.
Bloodshed Dev-C++ is using the MinGW (minimalist GNU) set of compilers. They are conversions of the GNU C and C++ compilers, which are the compilers used by most programmers, noobs and professionals alike, on Linux. The beauty of Dev-C++ though, is you don't have to go through hell and high water to set it up, unlike say, Netbeans.

I made a converter much like this a while ago - except it used loops to continually go through the program until the user typed in 0 (quit). If you wish me to rewrite it for you I'd be happy to oblige.

 

Get Visual C++ Express Edition

 

i got everything working... thanks

 

Kk Im glad to help

 

Too lazy to read the topic properly... why exactly does MSVC fail? I've used it for all my projects and it's fine.

 

i honestly dont know why ppls are still posting on this thread...
