C++ :: Outputting Transactions From A Text File To Screen
Jan 19, 2014
I am working on a wage application with four options which are as follows:
Subtracts an amount from the shop bank account (The account is text file "shop"). You do not need to add the same amount to another account but you should record the transaction with a timestamp in a separate file. The application should prevent the account balance from becoming overdrawn.
List the five most recent transactions to the screen. If there haven’t yet been five transactions then list all of them.
Print the account name, number and current balance to the screen.
Exit the program.
I have completed 1,3 and 4 but I am completely stumped as to how to go about number 2.
I have a partially filled array and I want to put that into a text file. Say I don't know how partially filled it is. How would I stop at the very end of the array where it has the last amount of data.
ex. int array[9] = {1,2,5,6}; ofstream output("txt file"); for(int i = 0;i < 9; i++){ output << array[i] }
How would I stop as soon as i becomes 4 because that is when the array stops?
I have a text file where in each line is 3 words and 2 int type numbers. I'm doing search by word and I want to print out to the screen the whole line where that word was found (the words is repeated in some lines). My search looks like this:
Code: #include<iostream> #include<string> #include<fstream> #include<stdlib.h> #include <vector> using namespace std; int main(){ vector <string> words; string str, paieska;
I seem to be missing a concept or 2 here ... I am tasked with writing a program that reads text from a file and outputs each line to the screen as well as to another file PRECEDED by a line number ...
In addition, I have to Print the line number at the start of the line and right-adjusted in a field of 3 spaces ...
Follow the line number with a colon then 1 space, then the text of the line.
Another kicker, is I have to grab the data 1 character at a time and write code to ignore leading blanks on each line.
Here is what I have so far:
#include <iostream> #include <conio.h> #include <fstream> #include <string> #include <cstdlib> #include <cctype> using namespace std; int main() { char next; int count = 0;
I am given a data file that contains sports data for 24 people. There are two rounds of the event. The first 48 lines of the file give the data for the 1st round and the second 48 lines give data for the 2nd round. The file looks like this:
Azrin, Neil 2.3 6.0 5.0 6.7 7.8 5.6 8.9 7.6 Babbage, Charles 2.3 5.6 6.5 7.6 8.7 7.8 5.4 4.5 Burks, Arthur 2.8 4.5 5.4 6.6 7.7 8.8 5.6 6.5 Crick, Francis 1.6 6.5 6.5 6.5 7.3 7.5 7.8 5.6 and so on ............
This data continues for all 24 people and then repeats with different score values for the second round. The first number after the persons name is the level of difficulty and then next 7 numbers are the scores. I am trying to get this data out of the file and set it up in the following format:
Name Of Person Round 1: level of difficulty scores Round 2: level of difficulty scores
So the table for the above data would look something like this: Arzin, Neil Round 1: 2.3 6.0 5.0 6.7 7.8 5.6 8.9 7.6 Round 2: 2.1 6.0 5.0 6.5 7.8 5.6 8.8 7.6 Babbage, Charles Round 1: 2.3 5.6 6.5 7.6 8.7 7.8 5.4 4.5 Round 2: 2.3 5.4 6.5 7.6 8.7 7.2 5.4 5.5
And so on for all 24 people. This is the code I have for it, but it just reads the file directly:
// I have already opened the file! while (inFile) { string name; getline(inFile,name); cout << name << endl; }
How I can do some sort of formatting on this data?
I wrote a program to compress a file with gzip, which works fine. I also wrote a program to decompress the gzip file, which runs but outputs a blank file.
I have screen scrolling working but i want to have text scroll with the screen. because at the moment my player moves and the screen scrolls but the text doesn't.
I am having a problem with my c++ code. I am attempting to clear the text off of the command prompt screen in a text based game program. I put a restart option using a goto in my program. How would I be able to clear all previously displayed text.
This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.
compiled with -std=c99.
Code: #include <stdio.h> int main(){ int maxsize; printf("How long is your message?
I am having a lot of trouble being able to get data from a file and input it into given structs and arrays of structs and then outputting the file. We are given a file that contains 96 lines and looks like this:
Arzin, Neil 2.3 6.0 5.0 6.7 7.8 5.6 8.9 7.6 Babbage, Charles 2.3 5.6 6.5 7.6 8.7 7.8 5.4 4.5
This file continues for 24 different people and then repeats with different scores (the second line). The first number, in this case is 2.3 for both people is a difficulty rating. The next 6 numbers are scores.
We are given this data in order to set up our structs and arrays and my code:
#include <iostream> #include <fstream> #include <iomanip> #include <string> #include <cmath> using namespace std; int main () { ifstream inFile; inFile.open("C://diveData.txt);
comparing with screen size the height is bigger but lenght is smaller. I don't understand.
I can understand that different printers process the fonts in different way and then to have different lenghts. That's not the problem. The problem is I need to simulate in screen the same behaviour i will have on printer because these texts are being aligned in the document, and I don't want to see that the text si aligned different in text than in paper.
What can I do to render the text on screen with the same size I will have on the printer? Print preview is doing it. Should I change the font parameters? is something related with pixels per inch?
How to open a file and just print what is in that file on the screen. I though maybe I had the directory wrong but putting G: or G: give me the same result. When I select 1 it just goes to the next line and doesn't print anything.
Code: int getchoice(void) { int num; int choice; FILE* outputfile;
I am having trouble outputting the file "output1.dat" to the screen. here is my code -
#include <fstream> #include <iostream> #include <cstdlib> #include <string> using namespace std; //Outputs a description of what this program does void intro(); void sort_merge(ifstream& in_1, ifstream& in_2, ofstream& out_1 );
I have a csv file (comma delimited text file really) and I have data ,about 6400 lines, and I need to read and display data from 1 line. At the bottom is sample data from my csv file.
I want to read onto the screen the 3rd item .. ie Test User 1 and the date and time at the end (the last 2 items).
I will enter in a number .. from which I will want to retrieve the appropriate record .. in this case I would enter in 514, 563 or 874 and get back the info for that record.
This is a DOS 16 bit application .. and I know that some of the data is in memory already but I am not sure how to tell .. or how to retrieve it.
I do have the ability to save the data to the file at any time .. so I can use that to ensure that the data is current in the text file before I retrieve the data from this 1 row.
I think that it may just be easier to get from the text file ? but I am not sure.
0000,7,0,"Test User 1",53c145cb,db,5,514,514,2014/07/12,10:27:23 0001,7,0,"Test User 2",53d7f,1903,10,563,563,2014/07/24,11:04:31 0002,7,0,"Test User 3",529c,5ffb03,0,874,874,2013/12/02,09:07:58
I am a database guy .. and I am just a bit lost when it comes to C programming as such.
My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.
#include<iostream> #include<iomanip> #include<fstream> #include<assert.h> #include<string> using namespace std; using namespace System; struct TStudent { string month[10];
[Code] .....
I noticed I had a 2 beside girl, after I removed it, it still didn't fix my problem.
I am trying to automatically(periodically) print screen a custom area of the screen, save it as an image file (the image will have the same format always), and then use OCR to get the text in the image as usable string variables. Is this doable? I was looking into tesseract OCR but I find it a bit unclear.
I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3 10110101 11111111 10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....
I want to make a program that opens a text file and checks the usernames listed in the text files to see if the names are registered on a site such as twitter. How easy would this be to make, what things would I need to know?
