I am currently working on a project for a class, and what I need to do is make a .txt file with a letter on the first line and two two-digit numbers on the second line, and have it write to another text file what the ASCII code for the letter and add and multiply the two numbers.
I've been able to get the code to compile, but it prints out strange numbers instead of what the answers should be. I've been told to initialize my variables, but when I set them to 0, thats all the program reads. So I get a file like, the ASCII is 0, and 0 + 0 = 0, and the like.
Here is the code. Please tell me where I am messing up!
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
ifstream inFile;
ofstream outFile;
char letter1;
double num1;
double num2;
inFile.open("input.txt");
outFile.open("answers.txt");
inFile >> letter1 >> num1 >> num2;
outFile << "The ASCII value of your character: " << letter1<< " is " << static_cast<int>(letter1) <
|
|
|
|
|
why are num1 and num2 declared as double ? I would try 'int' (looking at your input file example)..
int num1 = 0;
int num2 = 0;
what is that static_cast doing ? try
<< (int)letter1 << endl;
ok, thats old school these days, but Im an old f@rt, so it doesnt matter ... in the next two lines, bracket the operations so you get
<< (num1 + num2) << endl;
<< (num1 * num2) << endl;
the 'system(pause)' isnt doing much - you can step through your prog using F10 for example (if you're using MSVC) and look at the variable contents - or, sprinkle some 'cout' statments around to display things on the console/stdout instead of just to the file
ie
cout << "The Value of num1 is : " << num1 << endl;
|
|
|
|
|
I have just tried this as it stands changing only the static_cast(letter1) to (int)letter1, and the results are correct. Looking at your results I can only assume that the program cannot find your input file, but as you do no error checking there is no notification of that condition. Check the return value of the open call to see that it is not NULL.
I would also agree with Garth's suggestion that you use int rather than double for your numeric values.

Thanks a bunch for the help guys! For some reason my class is telling me that static_cast<int>(letter1) works fine, but I can't get it to work at all. (int)letter1 worked amazingly well. The system("PAUSE"); was only in there due to my debugging, so that got removed before the final submitting. I did switch from double to int, but was using double before because, well, I still haven't fully fleshed out the differences in int, double, and float. I found another problem I had was I put the input.txt file in as a source file, not a resource file, so that probably had a chunk to do with it also. Anyways. They are hitting us hard with this term in programming, and since it's all done online, I really didn't have anyone to turn to. Thanks again for bailing me out!

Glad you figured it out. Just a couple of things extra:
1. See here[^] for documentation on static_cast.
2. The different numeric types are:
2.1 int for holding values in integer format (i.e. without any fractional part) e.g. 1, 3, 212, 134788 etc.
2.2 float and double for holding values with a fractional (or decimal) part e.g. 3.14, 0.000497 etc.
Generally speaking it is best to use integer types unless you must deal with decimals, as they lose precision owing to the manner in which they are stored in computer words.

Can anybody direct me how to proceed wit this. I set already lib path
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib
But it dont help

I hope CudaMultipleBackPropagation is from a another library?
If so did u included that lib correctly without any mismatach from the header you included for that?

Do you have a path set to the Cuda library?
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Hi Adam, Tim
Yes paths to the CUCDA library are set OK, there is a path to header and object file.

The external reference CudaMultipleBackPropagation::~CudaMultipleBackPropagation(void) and others, cannot be found by the linker. This indicates that the object or library containing these calls is not being found. The reason could be either that the path to the library has not been set in your project, or the name of the library or object file has not been added to the linker parameters. Check your project parameters again to be sure they are correct. Incidentally the path C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include should be in your compiler include list not in your linker lib list.

I checked the directories. My object file CudaMultipleBackPropagation is located in directory
C:\Documents and Settings\Administrator\MBP_clone\MBackProp\MBPCuda\Debug
Under Linker/General/Additional Library directories i have
C:\Documents and Settings\Administrator\MBP_clone\MBackProp\MBPCuda\Debug
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib
so directories are ok. I also tried to copy object file to main project directory but it didnt help. Renaming Debug directory
to Debug1 also dont change anything, always the same linking errors
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include i put to include directories
|
|
|
|
|
Did you add CudaMultipleBackPropagation.obj as an input file in your Linker options?

after using 1st method to avoid wrong order linking and rebuilding solution im getting this
1>BackPropagation.obj : warning LNK4075: ignoring '/EDITANDCONTINUE' due to '/INCREMENTAL:NO' specification
1>LINK : warning LNK4098: defaultlib 'mfc90ud.lib' conflicts with use of other libs; use /NODEFAULTLIB:library
1>LINK : warning LNK4098: defaultlib 'mfcs90ud.lib' conflicts with use of other libs; use /NODEFAULTLIB:library

1>C
obviously its different problem now with LNK2019 because CudaMultipleBackPropagation.obj is defined in linker inputs

You seem to be getting nowhere fast on this and it all revolves around CudaMultipleBackPropagation.obj as far as I can see. I don't know where this module comes from but if you have the source you may want to try rebuilding it. It may be that this object contains a #pragma comment that includes the library that is causing the conflict.

So it complains about this call: CudaMultipleBackPropagation::DeviceLayer::Fire(int)
it is defined like this
void Fire(cudaStream_t stream);
Than it is mapped to FireLayer. So does it mean that the arguments of CudaMultipleBackPropagation::DeviceLayer::Fire so cudaStream_t stream dont map
to arguments of FireLayer ?? Why compilation passes than ??? What does it mean __entry after FireLayer ??

Where is the implementation of KernelFireLayer(). Once again you are calling some function in your code that is not being included in your link process. I have no idea what part of this is code that you have written and what part comes from some external library, but that seems to be the issue you need to resolve.

Obviously the bug is here i think, for all those functions LNK2019 occurs. But i dont know what this __entry means.
So it looks that because :Fire(cudaStream_t stream) has just 2 parameters and inside functions much more and they are not seen
from inside of Fire function so LNK2016 occurs. Do you agree with me ??
this cudaStream_t stream can not find anywhere how it is defined
Its not my code BTW.
void CudaMultipleBackPropagation::DeviceLayer::Fire(cudaStream_t stream) {
if (isOutputLayer) {
if(connections > MAX_THREADS_PER_BLOCK) {
KernelFireOutputLayer(stream, dimNeuronsPatterns, inputsBlockSize, inputValues, weights.Pointer(), m, mOffset, neuronsWithSelectiveActivation, desOutputs, outputs.Pointer(), localGradient.Pointer(), rms, lgSpaceNet, inputsWithoutBias);
} else {
FireOutputLayer<<<patterns, dimInputsNeurons, sharedMemFire, stream>>>(inputValues, weights.Pointer(), m, mOffset, neuronsWithSelectiveActivation, desOutputs, outputs.Pointer(), localGradient.Pointer(), rms, lgSpaceNet);
}
} else {
if(connections > MAX_THREADS_PER_BLOCK) {
KernelFireLayer(stream, dimNeuronsPatterns, inputsBlockSize, inputValues, weights.Pointer(), m, mOffset, neuronsWithSelectiveActivation, outputs.Pointer(), inputsWithoutBias);
} else {
FireLayer<<<patterns, dimInputsNeurons, sharedMemFire, stream>>>(inputValues, weights.Pointer(), m, mOffset, neuronsWithSelectiveActivation, outputs.Pointer());
}
}
}
<pre>KERNEL FireLayer(CUDA_FLOATING_TYPE * inputs, CUDA_FLOATING_TYPE * weights, CUDA_FLOATING_TYPE * m, int mOffset, int totalNeuronsWithSelectiveActivation, CUDA_FLOATING_TYPE * outputs) {
extern __shared__ CUDA_FLOATING_TYPE iw[];
int connection = NEURON * NUM_INPUTS_INCLUDING_BIAS + INPUT;
SumInputWeight(connection, inputs, weights);
if (INPUT == 0) {
int n = PATTERN * NUM_NEURONS + NEURON;
CUDA_FLOATING_TYPE output = CUDA_SIGMOID(iw[THREAD_ID]);
if (m != NULL) output *= m[PATTERN * totalNeuronsWithSelectiveActivation + NEURON + mOffset];
outputs[n] = output;
}
}

That's one parameter.
Krzysiaczek99 wrote: But i dont know what this __entry means.
Just a way the compiler has of generating entry point names.
It certainly looks like there are some mismatches between function calls and definitions. Since this is not your code your first port of call should have been the person whose code it is rather than posting it here. I suggest you try that route now.
