C++ :: Extracting Specific Lines Of Text From A Text File

Aug 2, 2014

I have a text file called (Test.txt) with the following text:

This is line one
This is line two
This is line three

How do I go about writing a program that will print a line of text (e.g. "This in line two" on the console screen?

All I can seem to do is display the entire text file.

I have a program here that writes employee information into a text file called employee.txt. I don't have a problem writing into the text file.

using namespace std;
int main(){
ifstream inFile;
ofstream outFile;

C++ :: Reading Lines From Text File

Jun 3, 2014

I am trying to read lines from a .txt file like this:

// "file.txt"
This is the first line.
This is the second line.

To do this, I tried using the following code:

int main() {
std::ifstream data;
data.open("file.txt");

[Code] ....

The output I want is:

This is the first line.
This is the second line.

However, all I am getting is:

This is the first line.

I can't quite see why this isn't working. I am decently familiar with file streams in C++, so I thought I would know what I was doing, but apparently not.

C++ :: Deleting Repeated Lines In A Text File

Jul 30, 2014

I have a text file with repeated lines, and i would like to get rid of the duplicate information, an algorithm to achieve this?

Example of my text file (the actual file may be huge, up to 500MB):

+Hello
+Bye
*The sun
-The moon
+Bye
/One coin
+Bye
+Bye
+Hello
*The sun

And i would expect to get something like this:

+Hello
+Bye
*The sun
-The moon
/One coin

I know how to open and read a file with fstream and getline(), but i don't know how to make the comparison.

C# :: How To Read Extra Lines Of Text File

Jan 12, 2014

private void open(object sender, EventArgs e) {
OpenFileDialog openDialog = new OpenFileDialog();
if (openDialog.ShowDialog() == DialogResult.OK) {
string[] lines = File.ReadAllLines(openDialog.FileName);
int k = 0;
while (k < lines.Length)

[Code] ....

So in this code, the user basically opens a text file from the dialog. Then the file gets read on all the lines and gets stored in an array. Now the reason I did this is because there are more fields of text boxes I have to fill in after I fill in the table (6x3). I'm getting an out of bounds error however.

19
19
19
0
95
0
0
0
0
5
0
0
5
1
0
0
51
1
110
Warrior

This is a sample text file that is being used. As you can see all the lines from start up until (excluding "110") will be used in the table. Now I want to read the last lines in this text file and put it in another text box. How do I do that?

C/C++ :: Skip A Range Of Lines In Text File

Apr 26, 2015

I made a program which read a text file and copies text in an another text file if line doesn't contain a specific string(code is below), how can I make it after it finds out a line which contains this string to skip n lines ? I tried to use a for loop but without any luck..

Here is what I did until now :

rfile.open("test.txt");
wfile.open("out.txt");
while(std::getline(rfile,line)){
n=line.find(name);
if(n == std::string::npos){
wfile<<line<<std::endl;
}
//Here is the "problem"

C :: Program Count Number Of Lines Of Read Text File

Jan 25, 2013

I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:

known_vector frame1 151 65 0 frame2 151.000763 64.538582 0.563737
known_vector frame1 152 65 0 frame2 152.000702 64.542488 0.560822
known_vector frame1 153 65 0 frame2 153.000671 64.546150 0.558089

Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:

0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000

C++ :: Declaring Arrays - Counting Number Of Lines In Text File

Feb 9, 2013

I'm creating a program to read information about class schedules at my school, reformat the information, and allow the user to search for specific semesters. There are eight fields of information. I'm reading the info from a text file using eight parallel arrays, but I'm having trouble declaring the arrays. I can run this code in one compiler (Dev-C++) with no problems, but I get errors when trying to compile it using Visual Studio stating that arrays must be declared with a constant value. I have a loop to run through the text file, with a counter to increment with each subsequent line, then I create a constant int equal to the counter, and declare the arrays of size equal to the constant int. Here's the section of code in question:

// Counting the number of lines in the text file
inFileForLines.open("CIS225HW1DA.txt");
string countLine;
int numberOfLines = 0;
//Discarding the first line of the text file containing only column headings
getline(inFileForLines, countLine);

C/C++ :: How To Assign Lines Of Text Using Combobox

May 5, 2013

So I'm working on program I had in Windows Form Application.

I have a combobox that lists the years 1981-2013. Beside it, a simple Enter button.

I wanted to be able to assign individual lines of text to each year that would be displayed in the message box.

Like if the user selects 1981, clicks Enter and the message box displayed "In the year of 1981.." but if they select 1982, the message box displayed "In the year of 1982.." I have everything else I want working, except that I can't figure out how to assign different lines of text to different years.

This code works, but not fully This code reads com ports, when a string is available, I check to see if it contains some keywords defined in array If it does, i print out the string itself.

The problem i am having is that it seems to stop processing the data at some point but I do know that there are more strings to be read. So, it does keep reading more lines of data

Visual C++ :: Reading Character Symbols On Lines Of Text Position By Position?

Mar 4, 2013

What I have to do is write a small program in C++ to parse the symbols that are used on 5 different lines of text in each position until position 30 is reached on each line. The goal of the parsing program is to interpret the symbols (characters), if there are any per each position, on the 5 lines of text in order to output the actual data that the group of symbols represents.

My question for is this: Is there anything special from a C++ environment that should go in to something like this outside of using standard stuff like the math associated with the search algorithm that has to happen here? The symbols are located in a file, so I know I have to include "iostream" and a few other headers. But outside of header inclusions and the code necessary to iterate and streamline the search and interpretation process, am I missing anything special that I couldn't otherwise find through simple google searches?
