C :: Printing Contents Of A File - Prints One Extra Character Not Present In The File
Feb 12, 2013I'm writing a program that stores records into a file and then these records can be printed out. A last name, first name, and score is stored to be exactly 36 characters long (using leading spaces to pad) making it easier to retrieve specific records. For example, three records stored in the file would like like this: (the underscores are simply to illustrate the distance, they are not in the file itself)
_______lastname_______firstname__90__________lname __________fname_100___________last___________first __60
When printed out, the names are formatted as follows:
lastname, firstname: 90
lname, fname: 100
last, first: 60
However, when I print them out this is what I get:
lastname, firstname: 90
lname, fname: 100$
last, first: 60H
For some reason, for any record after the first, an extra character is added to the end. These characters are not in the file, so I was thinking that the array for some reason wasn't being filled completely, (the array is initialized to size 36 and 36 characters are read from the file using fread) so it was printing out a random character assigned to the 36th array position. Except the character never changes, (always a $ for record 2, H for record 3, l for record 4 if i remember) and I've tried reducing the array size or the number of character read and it's the string that gets altered, the random character always remains. I figure the problem must be in the print_records function (appending seems to work no problem). Anyway here is my print records and appending records code.
Code: /*
- Prints a single record stored in the file pointed to by ifp.
*/
void print_record(FILE *ifp, int record) {

C++ :: Reading File Then Printing Data Onto Other File
Nov 7, 2014I am reading a file then printing the data onto the other file. It is working, however when I check to see if each variable is being properly set after reading the file a issue arises.
Example of the file being read
Code:
Vehicle PV50CAN passed camera 1 at 05:33:26.
Vehicle W867BRO passed camera 1 at 05:33:29.
Vehicle KQ63ARU passed camera 1 at 05:33:38.
Vehicle K954ITQ passed camera 1 at 05:33:40.
Vehicle V220MXB passed camera 1 at 05:33:42.

C :: Printing Of A File In Different Format?
Sep 13, 2013The requirement is to capture statistics of uuid occurrences for ALIVE/SEARCH/BYEBYE (it can be all 3, combinations of 2 each, or one alone) in a dynamically populated file in run time.
I am able to print all 3 combinations, but not in combination of 1 or 2 e.g.
If my input.txt is like this :
uuid:22314754-a597-490b-8a93-02cfae01036b ALIVE 16
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:50e65653-7525-485d-83bf-d293558c4264 SEARCH 132
[Code]...
Code:
#include<stdio.h>
#include<string.h>
struct uid
{
char uid_val[100];
char state[100];
int temp_count;
int alive_count;
int search_count;
[Code]...
Gives the following output ->output.txt)
Device ID ALIVE BYEBYE SEARCH
uuid:22314754-a597-490b-8a93-02cfae01036b 16 8 8
uuid:50e65653-7525-485d-83bf-d293558c4264 32 8 132
uuid:55076f6e-6b79-4d65-6497-180373763bc1 113 112 111
uuid:T0100203354 1 2 3
I want to generalize the code such that uuid occurrence does not have to be all 3 (ALIVE/SEARCH/BYEBYE), the occurrences can be any combination and code should work. e.g my code gives wrong results when input.txt contains the following:
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:55076f6e-6b79-4d65-6497-180373763bc1 ALIVE 113
uuid:55076f6e-6b79-4d65-6497-180373763bc1 BYEBYE 112
uuid:55076f6e-6b79-4d65-6497-180373763bc1 SEARCH 111
uuid:T0100203354 BYEBYE 2

C/C++ :: File Printing Out Data Twice?
Aug 10, 2014I have a file with data in it, and I'm trying to print that data, but it is:
1) not reading the last file (record #83)
2) it's printing out the last record twice (in this case, #77)
//record data for each tool
int recordNumber;
string toolName;
int quantity;
[Code]....
here is the printData() function
void Hardware::printData(int _recordNumber, string _toolName, int _quantity, double _cost)
{
cout << left << setw(10) << getRecordNumber() << setw(20) << getToolName()
<< setw(10) << getQuantity() << right << setw(10) << fixed << setprecision(2) << getCost() << endl;

//iter_swap – it just swaps the elements pointed to by the respective pointers without changing the pointers themselves. so, it's basically equivalent to the function:

*ptr2 = tmp;
}
// min_element – finds the location of the minimum element that exists in the given range. in this case,
it is the char* pointer pointing to the location of that element. it can be implemented like:
char *min_element(char *start, char *end) {

if(start == end) return end; // empty range
char *min_pos = start;

C++ :: Printing Out Bytes Of A File
Sep 4, 2012I am encoding some information in a binary file, and I want to check what I am doing by printing out all the bytes that represent the file.
This is being done by opening a pointer to the file with fopen, reading in each byte of data as a char, and then writing this char to the screen.
I have some image files (e.g. "image.jpg"), whose structure I know, so that I can test my program.
When I print out the chars, they are initially correct, and follow the structure of the file as expected.
However, after about 40 bytes, I find that every subsequent character is ' ' i.e. a blank character.
I then created a CharToBin function, which allows me to print out the actual bits in the char. When doing this, it shows that all the bits are 1 for the characters. i.e. most of the file is represented by 1's, which is clearly not correct.
This happens on all the image files I have tested, and furthermore, on several other non-image files. They all start printing out ' ' after a while. However, all these files are fine and not corrupted, e.g. the image files display correctly.
Code:
#include <fstream>
#include <iostream>
#include <sstring>
#include <string>
#include <stdio.h>
using namespace std;
string CharToBin(char ch) {
bool bits[8];
for (int i = 0; i < 8; i++)

C++ :: Printing From File One Word At A Time
Jun 27, 2013I have done an exercise from "Thinking in C++" to print text from a file to the console one line at a time, with the user pressing enter to get the next line.
My original code is below, how could I change it for one word at a time?
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
[Code] .....
I tried to alter my program to print one word at a time by changing "getline(in, word)" to "in >> word", but it prints each new word on a new line, the only input I have found to make the next word appear is Enter, I assume that's why.
Is there a way to make it print one word at a time when the user says, but on the same line?

C/C++ :: Reading Strings From A Text File And Printing Them
Feb 26, 2015I need a program that reads the number of lines of a file and then several (max of 20) lines of text from a .txt file so an example of the .txt file is: 2 This is the first string This is string number 2 So it first reads the 2 and then reads the two lines of text. It stores the text in an array of pointers. The code i have so far is:
#include<stdio.h>
#include<string.h>

C :: File Contents Printing And Saving With Filename Whenever Try To Send
Jan 2, 2015I am trying to establish a connection between client and server to send a file to the server from a client. I have been successfully able to send files to the server but i am facing a problem with the the filename whenever i try to send any string to the server and use it in naming the filename at the server side, the string is successfully concatenated but it saves the filecontents in the filename.
for example: i am sending a file hello1.txt to server and the server has to save it as abcxyz.txt as i am sending the "xyz" from the client. BUT Whenever i am doing this ,the file saves as abcxyzfilecontents.txt If i saved in the .txt file "you123" ,my file at server side would save as abcxyzyou123.txt
Here are my codes:
Know that the server code implements a multi threaded server. The functionality to be discussed is defined in myfunc

C++ :: Banking System - Searching For And Printing Values From TXT File
Mar 21, 2013So I'm doing a kind of banking system. Atm I've got the user able to create an account and set the balance of it, which is written to a .txt file. However, I would like the user to be able to enter their account no. and the program to cout the account info on the screen. I will be adding more to the program later, but until I work out how to search for values in a .txt file, and print out values on that line I'm a bit stuck.
