The brief is to write a program that implements a musically-interesting or musically-useful audio effect/process in C without external libraries other than those prescribed (PortMedia/PortMIDI/PortSMF/PortAudio, Libsndfile).
View 6 RepliesI've finished my series of tutorials and built a investment calculator with QT, now that's finished and I wanted to create a small radio that allows to retrieve audio from an URL. I wanted to use Juce but I'm clueless about it, I know how to program but I've never touched external libraries?

When I drag all the files in the project directory and write the statement #include <BigInteger.hh> on the top of the declaration of the main function, even whiteout any other code, I get lots of build error on the .hh and .cc file.

Write the definition of the class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sunday for Sunday. The program should be able to perform the following operations on an object of type dayType:
a. Set the day
b. Print the day
c. Return the day
d. Return the next day
e. Return the previous day
f. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.
g. Add the appropriate constructors
Write the definitions of the functions to implement the operations for the class dayType.
My code:
#include <iostream>
#include <algorithm>
#include <string>
using namespace std;
string my_Day[7] = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };
class dayType
[Code] .....
And here are the error messages that I get:
Line 23 error: prototype for 'void dayType::setDay(int)' does not match any in class 'dayType'
Line 11 error: candidate is: void dayType::setDay()
Line 36 error: prototype for 'void dayType::getDay(int) const' does not match any in class 'dayType'
Line 13 error: candidate is: void dayType::getDay()
I know this is probably a really easy mistake but I am new to Programming and I have changed this code for days to no avail.

I want to give audio-input to a FFT code (KissFFT) written in C, on a real-time basis. While I can give a simple test signal (like sine wave) by writing the sine function as input, I am not sure how I should convert an audio-signal (e.g.: song) into a form that can be taken as input by the KissFFT C code.

I am trying to call an external application in my C++ program , example, system("C:Program FilesInternet Exploreriexplore.exe"); but the application just gets closed.

2. the command that worked for me was "ShellExecuteEx"
This is the problem in detail:
I have a VC++ project to create a DLL that will be used as a Plug-in in an external programm. This DLL uses some MFC functions. The initial configuration of the project was:
-Use of MFC: Use MFC in a Static Library
-Common Language Runtime support: No Common Language Runtime support
-Runtime Library: Multi-threaded Debug (/MTd)
This configuration worked fine, there were no compilation errors and the resulting DLL worked correctly.
The problem came when it was necessary to add to the DLL some functions of .NET, using the namespace System and similar. To do that, I had to change the Common Language Runtime support, to Common Language Runtime Support (/clr). Then, when I tried to compile, I got this message:
'/MTd' and '/clr' command-line options are incompatible
So I changed the Runtime Library to Multi-threaded Debug DLL (/MDd). Then I got this error message:
Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version
So I also changed the Use of MFC to Use MFC in a Shared DLL.
After this, the compilation was correct. Then logically the size of the generated DLL is smaller, but this new DLL does not work correctly, the external program in which this DLL is used crashes.
I don't know what to do to fix the problem. Maybe I need to add some other DLLs or files to the directory where the DLL is located, where the external program uses it. But I would prefer to include a single DLL file, but this seems to be incompatible with the use of .NET functionality.
How is it possible to store the related data of a program C++ into an external file (like as .txt) and retrieve it?
I want to write c++ program that can contain data members " id and phone"
like as
Code:
class profile {
private: int id,phone;
public:
void retriever() {
cout<<"Enter your ID: ";
cin>>id;
cout<<"Your Phone number is "<< phone;
};
}
avoiding formats in above class, purpose is to store data already in txt file with different id and phone numbers and it is to be retrieved by matching id number to txt file and viewing its related phone number.

A sequence point in a C program is defined as "Any point in a program's execution at which it is gauranteed that all side effects of previous evaluations will have been performed and no side effects from subsequent evaluations have yet been performed."
What is a side effect?
I have this code:
tgaManager.fileWriter.put((unsigned char)min(blue*255.0f,255.0f)).put((unsigned char)min(green*255.0f, 255.0f)).put((unsigned char)min(red*255.0f, 255.0f));
that should pass the value decided by the min function to an ofstream object, filewriter, that call the put method to print chars in a tga image file. When I open the file, all I see it is a huge black screen. You may be thinking that the values of blue,green and red are all zero but it is not the case.
With this code:
if (x==50 && y==50) {
cout << "Min BGR: " << endl;
cout << min (blue*255.0f,255.0f) << ' ' << min (green*255.0f,255.0f) << ' ' << min (red*255.0f,255.0f) << ' ' << x << ' ' << y << endl;

I have a program that I can only run one instance of. When I try to start it a second time, it doesn't do anything. I would like to create a script that loads the program in a way that I can run multiple instances. Since I assume the program checks the process tree on startup to see if an other instance is already running, I figure disabling access to the process tree could do the trick.

What I have: A basic program for infinitely looping after and testing for an active process. It has a delay system built in to make it so it is not constantly iterating.
What I need: A way to get process IDs from other Processes other than my program. With a way to use that ID to detect if that process is active on the computer or not.
Parts of my code that need changing:
/* Code for handling the process would go here */
/* Code for detecting the target would go here */
What the goal of my program is: Perform operations to terminate the process of cmd.exe when it is active on the user's computer. Then output the status of the process and the time it took to find that process to the user.
It contained functions that I needed, but I need more information on how to apply them to other processes instead of the parent of my program and its' children.
Here is the code I prewrote for this so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ZERO 0
#define INFINITE 1000000000000000

I have written library in c++ for c++ application. Here, data exchange between library and client through structure. This structure has 20 members ( strings, integers, reals, pointers).
In some flows, library needs few members should get filled in the structure. for ex, application filled 3 integers information and passed to structure. But, in memory, whole structure is occupied.
I think, If library provides functions for every combination, then it would end up with lot of functions. I want to avoid that.
How to optimize data exchange between client and library? ( number of members may be filled sometimes 1, 2, 3, .. 20)
Is there any way to do date math using standard C libraries? I looked around in the time.h but didn't see what I needed.
What I need to do is be able to add a certain number of minutes to a date and have it give the current date/time. For example, add 15918765 minutes to 01/01/1980 00:00 and have it tell me 04/07/2010 4:45PM. I really don't want to write this myself or go platform-specific.
Does this exist somewhere or am I SOL?
I know I can use -isystem path to mark a path as containing system headers which shouldn't be included when generating warnings, and this works, but it doesn't work when the warnings are generated by instantiating templates from the library in my source code. Is there any way to ignore these template-instantiation-generated warnings too?
