how could this program tell the ID's and Passwords of more than one line in the text document?

So I need to make a program that counts the number of words, lines, and vowels in a program. Punctuation and white spaces are not counted in any of the counts. I have this so far and the words, and lines work and are correct but I can't seem to get the vowel count to work.
#include <iostream>
#include <fstream>
#include <cmath>
#include <cstdlib>
#include <string>

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
I am trying to make my program read an integer until a space, namely ' ', is pressed, and then move on to the next command. However, all my attempts hitherto with both scanf() and getchar() have been to no avail. Every time it proceeds to the next command only upon pressing Enter, which is not quite what I want.
View 3 Replies View RelatedI am trying to read lines from a CSV file and put the values into vectors. The CSV contains a large amount of data and I would like the program to only read certain lines from the CSV into the vectors. An example of the data is below. In my code the user inputs a secid. I would then like the code to only read lines from the csv where the secid matches what the user inputs. The secid's are also not in order so I can't just use a while loop.
My current code is below the data.

My task is to write a function for borrowing books form library called borrow(name,surname, student_id, book_id), which will connect information of borrowed book's ID and student's information in the file.
File looks like this:
John Jackson 45 0
Michael Gregory 34 56
Ann Cawitch 23 0
Chris Lamb 34 50
...
First two words are name and surname of students. First number represents student's ID and second one represents ID of book. If ID of book is 0, it means that student hasn't borrowed book yet, so he can borrow some book. If ID of book is not 0, it means that student can't borrow a book until he returns the old one. So, when student borrows book, ID of book in file should change from zero to some number
This is my code:
void borrow(string name, string surname, int student_id,int book_id ) {
string a;
string b;
int c=0;
int d;
fstream f2;
f2.open("students.txt", ios::out |ios::in);
[Code] ....
Whenever I call function (for example borrow(John, Jackson,45,15)), I get answer "Student isn't sign up library."
Am I on a right path? How to make this code to work?
I'm trying to make a program that reads data from a text document and allows me to modify it. I am stuck with the display() function. I can get the printf statement to display all my array values except the char AD value. When I include flight[i].AD it causes the program to crash. When I run the program to only display the AD variable I get a bunch of weird symbols. I'm not sure where the program is going wrong because it seems to be storing values properly except for the AD variable.
#include <fstream>

const int SIZE=20; //maximum characters

I have to txt files, and want them to read into an array line by line and after then a split the lines with delimeters, at the first file I use ";", at the second file I want to split the lines to single words by spaces. My aim is to get the first word from the first file and compare with all the words from the other file, to check is there any matches.
My problem is, that at the first file works everything fine, and I want to do the with the second file, but after reading the lines into lines_input[], I check the an empty = null line, I get segmentation fault.

I am writing a code to read a file and break it into lines and characters but I am getting an error do not know the reason for it though.
here is my code
#include<fstream>
#include<string>
#include<iostream>
[Code].....
The first line is executing properly but when it goes to the second line I get an error "the program has stopped working"
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

private void open(object sender, EventArgs e) {

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.

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?

My program does compile and counts the number of lines of code, which is LOC: 20. My issue this, according to my code instruction it should not count comments (//) and also shouldn't count blank lines of code. Unfortunately my code is counting // and white space.
What seems to be working is #, all three includes are not being counted. That’s a good sign. I’m using the same technique not to count #. Why isn't working for comments and blank lines? I’m pretty sure that my logic is correct. I think my problem is maybe syntax.

C program to count the number of lines in a text file and reverse the contents in the file to write in an output file.
ex :
input
one
two
three
output:
three
two
one
Code:
#include <stdio.h>
main() {
int c, n1;
n1 = 0;
while ((c = getchar()) != EOF)
if (c == '')
++n1;
printf("%d", n1);
}
I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.
Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.
im trying to read in 1 array and get 2 as outputs from 3 different functions.my read array is easy enough were im getting confused is how to read that array, separate it and take out only the parts i want and place them into a 2nd, then again a 3rd array.i have the following so far:
Code:
#include<stdlib.h>#include<stdio.h>
#include<unistd.h>
#define SIZE 10
}

this compiles without a complaint, but when i go to run it no longer responds after taking the 10th element (well 9th if counting from 0).I think i have the if correct for the even odd section, but when i try to populate B or C array with the output of that if statement from A is were i think things are dying...
