C++ :: How To Separate One Line Into Two (or More) Strings At The Tab

Nov 3, 2013

i'm reading from a text file which includes a dictionary in UTF8. it has the following structure:

word, bla "bla" translation

so there's a word and a translation seperated by tab. both can include any kind of charactars, excluding tab of course, especially blanks (found one code that claimed to seperate a string at tab, but also did at blank).

how can i seperate one line into two (or more) strings at the tab? i've been searching for a while, but can't find anything useful...

C/C++ :: Use Fscanf To Obtain A Set Of 14 Or So Strings Per Line?

Feb 25, 2012

I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:

FILE *d;
d=fopen("t.dat","rb");
where a, n are all strings.
fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,..(etc)..,&n);

A sample of the Input file looks like this:
USB270.15385-29.63146 270.153847 -29.631455 2.966699e+03 -9.99 1.300391e+03 -9.99 -9.99 A-A-- 6.787463e+01 -9.99 1.555773e+02 -9.99 -9.99 10100 | ----- ------ ------ ------ | 0.373 13.554 12.928 12.670 AAA | ----- -------- - -------- - -------- - -------- - | --- ---------- - ---------- - --------- - --------- - --------- - ---------- -

C :: Reading A File Line By Line (invalid Write Of Size X)

Aug 17, 2014

I am trying to read a file line by line and then do something with the informations, so my method looks like this:

Code:
void open_file(char *link) {
FILE *file = fopen(link, "r");
if (file == NULL) {
fprintf(stderr, "Could not open file.
");
exit(EXIT_FAILURE);

[Code] ....

1) The first complain of valgrind is at the line where I use fgets and its telling me (invalid write of size x), but I have allocated my line to 56000 and the read line is shorter, why is there a write size error then :S?

2) at the line where I realloc where I try to shrink the space he's telling me: Address .... is 0 bytes inside a block of size 56000, But I know i need only this space so why is there a write over space error :S??

C :: Reading A File Line By Line And Storing It Backwards Into A List

Sep 25, 2013

So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4

The code should store each line in a list as such...
4, 3, 2 ,1

Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4

Here is my code...

struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}

Is possible to pick a single point (location) from that bmp image (Not the whole window)?

i like to plot a line graph using the pointed single line data using the stored file data?

here R is X Axis and G & B is Y Axis.

If i have 2D array of data means how can i plot the line graph?

I'm trying to parse, or tokenize strings that follow the program name/command when used command line. I want to use the command followed by a sentence with a period. I know I need to user argv. But how can i parse the command rather than prompting the user for input. The input will be a sentence.

C++ :: Longest String Does'n Print On Same Line

Aug 4, 2014

I try to learn string class, resolving some problem, but i have some dificulties.The is ok, but when i print the longest string it does'n print on the same line.I enter the number of string, after that i enter the first string until i introduced from keyboard "#" character. I enter the second string and so on.Look at these example :

For i = 3;

Text[0] : I learn class String#
Text[1] : I dont learn class String#
Text[2] : String#

It print me like that : Text[1] :

I dont learn class String More than that look at the next example :

For i = 3;

Text[0] : I learn class String#abcdef
Text[1] : I dont learn class String#
Text[2] : String#

You see that in the first sentence i have continue to introduce some characters after # character and look what is happened :

Text[1] : abcdef
I dont learn class String

#include<iostream>
#include<string>
using namespace std;
int main() {
string text[100], cuvant;

C/C++ :: How To Print New Line Without Carriage Return

Jul 28, 2014

I am using C++ to write data into a (.ini)file. However, when I try to print the value '0A' I am getting '0D 0A'. (this is what I see when I copy the output to HexEdit). From what I can figure out, '0A' is the ascii for 'new line' so write function automatically adds the '0D' which is 'carriage return'. What I want is to print 0A alone. how can I do this?

Note: Windows it is working fine, but linux it is not working...

unsigned char arrRes[4];
int N = 10;
memcpy(arrRes,&N,4);
std::ofstream Output(LUT_OUTPUT_FILE_BINARY,std::ios_base::binary | std::ios_base::out);
Output.write((const char*)arrRes, 4);

here 10 means 0x0a but it is printing 0d,0a...

C++ :: Read Line By Line From Text File To String

Jul 5, 2013

I have a text file (test.txt) with the following data:

01,05,25,20130728
01,06,25,20130728
01,07,25,20130728
01,08,25,20130728
01,05,25,20130728
01,05,25,20130728
01,05,45,20130728
01,05,65,20130728
01,05,85,20130728
01,05,35,20130728
01,05,25,20130728
01,05,35,20130728

I want to read this to one string called line. So far I have this code:

string line;
ifstream myfile ("/home/Test.txt");
if (myfile.is_open()) {
while (myfile.good()) {
getline (myfile, line);
for (int a = 0; a <= 335; a++) {
cout <<line.at(a);
} }
myfile.close();
}

so far its only printing the first line and then throwing an instance of 'std::out_of_range'

C++ :: Read Txt File Line By Line Write To Vector

Oct 5, 2013

I need to read a text file which has various lines containing integers. I need to write those integers separately in a vector. Example, the first line of the text file contains 3 9 8 7 6 so vector[4]=3, vector[3]=9, vector[2]=8 and so on. Next read the second line 4 1 2 3 4 5 and write to another vector vector[5]=4, vector[4]=1...

I tried the code below but it will write from the second line, the whole line in one vector index.

int str; // Temp string to
cout << "Read from a file!" << endl;
ifstream fin("functions.txt"); // Open it up!
string line;
// read line count from file; assuming it's the first line
getline( fin, line );

[Code]...

C/C++ :: Reading From A File Line By Line With No Specified Number Of Values

Apr 12, 2015

Im trying to read from a file, line by line, with no specified number of values in the file. Check out my code:

int main() {
string x;
ifstream fin;
int count = 0;
char ch;
fin.open("CWC_Master.txt");
if(!fin)

[Code] .....

Now, this works great! However, its skipping some lines. And I dont know why. For example: Lets say that the input file is:

superman toy
sm2335
19.99
batman toy
bm5532
25.99
aquaman toy
am6786
26.00

Where it should output the above, instead it outputs every other one. Like:

superman toy
19.99
batman toy
25.99
aquaman toy
26.00

How can I fix my code so that it SIMPLY(i say simply because I am still a beginner coder) can read line by line?

C++ :: String Operation While Reading Line By Line From A File

May 12, 2014

I have to read the information about logic gates from a file. The file format is shown below:

Code:
gateOne = NAND(inpA, inpB)
gate2=NAND(1,2)
3 = NAND(23,25,26)

As, it can be seen from the above structure that whitespaces are not same everytime. So, to deal with this situation, i am using boost library to remove all whitespaces from the line which is being read and then try to find the name of gate and its input. My code is given below which is able to correctly find the gate names and its first input...but my code is not able to find the second, third and so on input names.

Code:
//C
#include <stdio.h>
//C++
#include <iostream>
#include <sstream>
#include <fstream>
#include <string>
#include <cstring>
#include <boost/algorithm/string/erase.hpp>

[Code] ....
