I am trying to get user's voice as an audio input to a c++ program and store it in a text file (.txt)
I have been searching over the web to find some kind of library or something like OpenCV(video library) for while now but nothing seems to be there.
I need to store the last 3 deposit that I have in my deposit. I have few option but i dont which would be easy
1.Store all deposit to the text file (store always in a new line), and display the last three deposit from the text file.
dep 1 - 60
dep 2 - 40
dep 3 - 100 print 100
dep 4 - 50 print 50
dep 5 - 50 print 50
2. I think this option is more difficult, when it reach deposit 4, to get rid deposit 1
So when i make a deposit 4, the deposit 1 get's ride
dep 2 - 50
dep 3 - 100
dep 4 - 70
Right now i can only display one deposit (last one), then i close the program and run again and i make another deposit it overwrites a new deposit.
My code.
To show sure my deposit that has been made.
double depSave () {
int option;
float dep1,dep2,dep3;// Declare your variables
dep1 = dep2 = dep3 = 0; // Set them all to 0
system ("cls");
string path = "deposit.txt"; // Storing your filename in a string
[Code] ....
Where is says "save deposit" in comment that where it saves to the deposit text file, that going to be output to the depSave function.
This my deposit function, i want to open the file (balance), then add the sum and store in on the text file.
float deposit( int x, int currentBalance) {
cout<<"
"<<endl;
cout<<"Welcome to the deposit area"<<endl;
cout << "Your new balance is:" << balance <<endl;
[Code] ....
So I have a project in which I am processing audio signals in real-time. I want to create a class to do this using the ASIO driver. I don't want to use a cross platform library nor do I want to use windows API as it is very slow.
View 2 Replies View RelatedI'd like to input a file and store the contents of the file in a string.
Here is my code:
std::string inputFile();
int main() {
std::string fileContents = inputFile();
} std::string inputFile()
[Code] ....
It works fine if the file name and path is input correctly.
But, if the file name or path is entered incorrectly, the recursive call to inputFile is executed, and the user is given another opportunity to enter the file. Then, if the file name is entered correctly an error is thrown in Visual Studio 2013:
"Unhandled exception at 0x77F7A9E8 (msvcr120d.dll) in Assignment4.exe: 0xC0000005: Access violation reading location 0xCCCCCCC0."
How could this be done better?
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.

Then, when asked, could compare the results to other entries in the so called "data-base" and tell which is the best match. I tried a whole lot but couldn't think of a proper way.
(Stings and File IO are not my strong points)
I am using Code Blocks 10.05 and the standard GCC compiler.
read a text file and store the file contents into a 2D array?
100 101 102 103 104 105
106 107 108 109 110 111
112 113 114 115 116 117
118 119 120 121 122 123
124 125 126 127 128 131
Here's my code:
const int ROWS = 5;
const int COLS = 6;
int array[ROWS][COLS];
ifstream inputFile;
inputFile.open("table.txt");
[code]....
When i run the program and try and display the array, it doesn't work.
I have a text file in the form
5502 5202.3
1523 2536.1
1254 1256.2
17846 8956.2 and so on
left one is time and right one is pressure, I need to show the time value as it is but i need to use the pressure value to calculate air speed. I don't know how to use the strings to pick up the list properly. I did the calculation formula for the air speed but i can't pick the pressure value up from the text file. here's what i did:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
[Code].....
I am trying to store the contents of a text file into a char array. However the function i am using ifstream member function get(); seems to stop working when fed with certain characters. Is there another solution besides the get() function that will accept all types of characters from files?
char text[1000];
for (int i = 0; i <= textlen; ++i)
{
text[i] = text_in.get();
}
how I can read information from a text file into an array so afterwards I can display the array and it will show the contents of the text file?
the information inside my text files consist of names and numbers like so: "Collins,Bills 80" should I separate the numbers and names into two separate text files one for names and one for numbers?
My code so far is this:
#include <iostream> //for cin and cout
#include <fstream> //for input/output files
#include <conio.h> //for getch
[Code]....
C++ code that will take the existing comments from a arbitrary C file, and store those files in a text document?

I'm trying to read the data from a file i/o and put them into an array of structs. But when I run the program, it gives me a bunch of "garbage" as an output. my code and see

ifstream wormfile("worm.txt");
ofstream dtfile("dt.txt");
[Code] ....
worm.txt has
Code:
I like pie
I like rice
and I like applesauce
while dt.txt has nothing
I was able to get the lines in worm.txt and get it to copy the lines to dt.txt BUT it looks like I can do this in some kind of if statement or while loop. The reason why I don't like to do it the way its in the code because I could have another file that has the lines that I don't know and the code comparing them would take less time then me looking at the file, counting the lines and putting x lines of getline functions in the code.

I am writing a spell checker for a exercise for a class I am taking online. I have to load a huge text file of 143092 words into a hash table.
The program segfaults on word number 63197. Is there a way to debug this in gdb without having to step threw the function 63197 times.
i am doing some practice problems and i can't seem to figure out how to do this. basically we have a students number of test scores, then the name followed by the scores they have in a text file. Then we have to make a class with a constructor, copy constructor, destructor, and overload the = operator and the input and output operator. Are we suppose to call the text file in the input overload operator?
Here is what i have so far.
This is my header file.
#ifndef STUDENTTESTSCORES_H
#define STUDENTTESTSCORES_H
#include <string>
#include <iostream>
using namespace std;
class StudentTestScores{
private:
string studentName;
[Code]...
i am 100% sure the overloading the input is wrong
here is the implementation of the constructor copy constructor and desctructor
#include <iostream>
#include "StudentTestScores.h"
using namespace std;
StudentTestScores::StudentTestScores(string name = "", int numScores = 0)
{
studentName = name;
numTestScores = numScores;
if (numScores <= 0)
testScores = NULL;
else

I'm looking to convert audio, images, video to base64 in c++, and through many searches on the web I've only seem to come up with string > base64.
When I view a .mp3 file for example, there are many characters there that are not available to be used in my string to encode.
[URL] ....
I have this code set up in my project, and all I want is to be able to give the location of any file and have it encode (could just encode to a string, I can handle writing it to a file), and then give a location to put the decoded file as well.
I'm not sure exactly where to even start.
I need to make a program which can play a audio file as background while executing other operations .

Here is the assignment... Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;
and define two namespace globalTypes (tys and fys) for the function :
class_level deriveClassLevel(int num_of_credits) ;
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy. And the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
and this is the code I have so far...
#include <cstdlib>
#include <iostream>
#include <cctype>
#include <fstream>
using namespace std;
enum class_level {FRESHMAN, SOPHOMORE,JUNIOR,SENIOR};
class_level classLevel;
[Code] .....
My main question is did I use the namespaces and enum correctly? And my second question is whats the best way to input the data from the text file? This is really where I get stuck.
