I am trying to store a large text file into an array so I can count the number of characters.
View 2 Replies View RelatedI'm trying to type out whatever is in the .txt document, but I cannot open it for some reason. My code is
Code:
int main(int argc, char *argv[]) {
char ch=0;FILE *fp;
fp=fopen("C:UsersPCDesktopNew folderQuestion 5one.txt",'r');
while(ch!=EOF){
printf ("%c", ch);
ch=getc(fp);
Sleep (200);}fclose(fp);
return 0;
}
I keep getting an error with my fp=fopen so how do you open the text? Do i have anything else wrong with my code.
I need to create a text file that looks like:
first line
second line
third line
forth line
fifth line
sixth line
I want to replace the third and forth lines with three new lines. The above contents would become:
first line
second line
new line1
new line2
new line3
fifth line
sixth line
How can I do this using c++?
never was taught file function in c++
I'm having trouble opening a file from a specific location.
#include "maidcafe.h"
....
char directory[80] = {"C:UsersPublicDocumentsAnime NotesTransaction"};
char code[20];
printf("Enter file name");
gets(code);
strcat(directory,code);
system("start "" %s",directory);
i thought this would work, but it didn't xD. I got an error
I have the following complete code in c++
Code:
void GetMapData () {
MapPair NewMap;
string TempString;
BOOL SkipReadLine = FALSE;
//------
char buffer[MAX_PATH];
std::fstream File;
[code].....
The problem is that I do not want to have an external MapData.txt, rather I access it through a embedded text resource, which in this case I have no knowledge on doing so.
I have the following snippet which demonstrates to my knowledge on how to access a text resource; however, I do not know hot to modify the code above to implant this, but to still have the same functionality as the original code above.
Code:
HRSRC hRes = FindResource(GetModuleHandle(NULL), MAKEINTRESOURCE(IDR_TEXT1), _T("TEXT"));
DWORD dwSize = SizeofResource(GetModuleHandle(NULL), hRes);
HGLOBAL hGlob = LoadResource(GetModuleHandle(NULL), hRes);
const BYTE* pData = reinterpret_cast<const BYTE*>(::LockResource(hGlob));
note that I am compiling with a MBCS.
I'm reading from stdin a line. With that line, I should open a new textfile with the first letter of that line on a certain directory. My code is the following :
Code:
int main() {
char line[BUFSIZ];
FILE *ptr_file;
int x;
while(fgets(line,BUFSIZ,stdin) != NULL){
[Code] ....
char caminho[] is the directory in which I want to create the text file and chave will be the first letter of the line in stdin.
How am I supposed to use strcat to get these two together in a string to then use ptr_file =fopen(caminho, "w");
I am in an "intro" C++ course and am having trouble with a section of my current project.
We are required to open a text file, read the data from that file, and print it back.
However, we are supposed to let the user input the name of the file that is to be opened. This is the code I have so far. It is not opening anything.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int NUM_QUESTIONS = 30;
typedef char CharArray[NUM_QUESTIONS];
string fileName;

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.
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 was trying to make a program in C that could take Personality Information from the user and store it in a text file. 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");

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;

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

C++ code that will take the existing comments from a arbitrary C file, and store those files in a text document?
View 4 Replies View RelatedThis is part of my code. what i wanna know is if there is a way to fill this array until the text is over instead of having to set the number of strings in the file (20). And then store that number into a variable.
int main() {
//array:
string words[20];
//file to open:
ifstream file("test.txt");

I want to open one new CMD from console application, write text into the new CMD and then coming back to the control on the old cmd. (like interactively working on the both)
look into the below code
Process P1 = Process.Start(@"C:WINDOWSsystem32cmd.exe");
P1.StartInfo.RedirectStandardInput = true;
P1.StartInfo.RedirectStandardOutput = true;
P1.StartInfo.UseShellExecute = false;
StreamWriter wr = P1.StandardInput;
wr.WriteLine("First line in New Cmd");
Console.WriteLine("First line in Old Cmd");
wr.WriteLine("Second line in New Cmd");
Console.WriteLine("Second line in Old Cmd");
it is giving the exception "StandardIn has not been redirected"
so in this program i have two structs
struct node{
string data;
node* next;
node* prev;
};
struct list{
node* head;
node* tail;
};
one is just nodes for a doubly linked list and the other one stores head and tail pointer.
I am creating a function that creates the list and returns the list, (which will be a head pointer and a tail pointer).
list* read(string fn){
ifstream file(fn);
node* no;
string temp;
lista* bn;
bn = new list;
[Code]...
why is this not working?
I have a folder "pics" in g: drive. There I want to create some text.txt file. Thus, the final path is "g:pics ext.txt".

I got an assignment at school asking for a program that can implement functions that store, get and deletes text/binary data to a given memory area. We are supposed to make kind of like a tiny-mini OS..any links to some tutorials or explanations hon ow to understand this and be able to make a program like this on my own?

Of course the last bit wont be running for you, since the variables are missing. My question now is, that I like to open this file in a text editor. The file should be opened with a command withing the code. Is that possible at all? As you might can tell the receipt should pop up after the program ran and the user should be able to print it afterwards.
For homework I need to take a file of numbers (double) and fine their average. But, I seem to be having an issue just opening the file.
#include <iostream>

// Precondition: Reads all the numbers from input file stream
// Postcondition: Prints out to the screen the average of the numbers
