Then will split as string on every '|' char and according to this flag |A|, |D| or |M| I will add/delete/modify information inside. I have trouble with this part with the connection and read/split file and check for the flag A, D or M.
how to split a file in equal size and when clicking on split button it split the files as well as encrypt split parts and the size information are automatically stored in groupbox and save all splitted files in folder.
How to create text file in C programming. And after some changing in that text file off the running code of C, I want to read that modified text file back in C running code. e.g
Created file may have number 1, after changing this value to 2 let say, than I want to read that 2 value which is in text file.
I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream> #include <string> #include <sstream> using namespace std; int main() { string str = "3 J JD,K"; stringstream ss(str);
[Code] ....
Output of the code is 3 J JD k
but I want 3 J JD K
Also after I split the string is there any way to put the split string into individual string variables.
Now if i were to add true/false values to my arduino string, im not sure to read it. I would like the bool values to enable/disable led jpegs to simulate output status.
rly1_led.enable = newData[15];// if true
Ive tried everything and just cant figure it out. This is my first C# project.
I am having trouble with parsing out string value into a 2D vector. Suppose i have the string "attack at dawn " consisting of 15 characters, i will like to store it into a 2D vector with 5 rows and 3 columns and the result is as follow.
Vector[0][0] = "a" Vector[0][1] = "t" Vector[0][2] = "t" Vector[1][0] = "a" Vector[1][1] = "c"
How delimiter work. I need write a function that splits the string by delimiter. Function header is:
vector<string> split(stirng target, string delimiter); for example, the code inside main calling your function vector<string> v = split("hiAAAmyAAAnameAAAis", "AAA"); and v should come out as hi my name is
So is it something like vector<string> split(string target, string delimiter) { vector<string> word; string s = "hiAAAmyAAAnameAAAis"; string delimiter = "AAA";

Here is a draft code that i did but is not working as desired.
vector<vector <string > > plaintextVector; vector<string> row; string totalString = "attack at dawn "; int dimension = 3;
I'm currently trying to code a sorting algorithm program.
let's asume I have a string given: aa, aaa, bbb, bas, zya!
I first of all want to split the given string on commas and '!' tells the program the string ends here and is no part of the last word. lower and upper case is not important at the moment. trying to implement everything with standard libary
output should be like that ofc: aa aaa bas bbb zya
I already looked into the bubble sort algorithm and I think it benefits my needs. Just wanted to know how I should start out with the string split.
I'm reading lines from a text file in C++ which contains integer + string + float number(like 3,67 with comma) + string in this order. I need the float number to sort the lines but I couldn't manage to separate the data into the types I can use so far. I tried different kind of functions and the best I could do was such a code;
void main (){ ifstream records; records.open("records.txt"); int id; string line; char name[100]; float gpa;
[Code] ....
This fails at reading the floating number which has comma in it and then last string is read as string starting with the comma and rest of the number. An output example is:
698 John 3 ,67
It doesn't read last string on the line as well. I understand that part but simply I need another read but what I want exactly is to separate one line using "tab" as a seperator into proper data types and then using the numbers as integers, and the grades as floating numbers. How Can I do this?
I have an EDI file whose structure is given below. This file has multiple records, each record contains a header (e.g EDI.DD.0000000001.20130809), then contents (i.e multiple paragraphs of text) and then footer (e.g End of Report/No EDI Activity). I have to read that entire file using regular expression using three groups.
I am using following regular expression to read the file.
That expression reads the "header" and "footer" in respective groups properly but didn't pick the contents between header and footer in "contents" group.
I have changed the font of header and footer in below file to understand the format. I am using asp.net 3.5 framework.
//------------------Start of EDI File---------------------// EDI.DD.0000000001.20130809

I need to find a string(&login=) from physical memory dump file.And i have to print the word or string following it.Is there any C# code for this problem?
I'm trying to make a program that will read in names and grades from a text file and print them in the console. However whenever I try to use the OpenFile.get function I get an error saying that there is "no instance of overloaded function"
getting this error resolved before I can.
my code so far (I know it's missing a lot, but that's not what I'm worried about right now.)
I'm trying to read all content from a text file into a string. This is the code I'm using for it (I know there are other, maybe better ways to do it but I'd like to stick to this for now):
char* buffer; std::string data; FILE* fp = fopen("textfile.txt", "rb"); if (!fp) { printf("Can't open file");
[Code] ....
So my problem is that I get an exception when I try to free the memory -> 0xC0000005: Access violation reading location 0x51366199
I even get the exception when I try to free it immediately after calloc() but why this is.
And if I use buffer = (char*)malloc(lSize); I don't get any exceptions.
I want my program read the file and when encounter any enum type, instead of treating it as a string, I want the program store it in memory as a enum value.
How can I do that?
string s; ifs>>s; s // how to convert it to enum???
If your strings are all well-formed it is possible with the following regular expression:
String[] res = str.split(",(?=([^"]|"[^"]*")*$)");
The expression ensures that a split occurs only at commas which are followed by an even (or zero) number of quotes ... and thus not inside such quotes).
Nevertheless, it may be easier to use a simple non-regex parser.
But the .split gives me an error and .Split doesn't work either.
I try to use passing function as argument but I'm stuck. I have two questions: First, I try to call uppercase and open .txt in tfm Second, How can I read characters from in.txt as string and assign to char content[] ?
#include <stdio.h> void tfm( char str_filename[], void(*pf_convertion)( char content[])); void uppercase(char content[]); //converts all letters to uppercase int main(){ puts("-------------------------------"); printf("tfm: "); tfm("in.txt", uppercase);
I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,
N,N'-dimethylethylenediamine.mol
This is the function that opens the file :
Code: // opens mol file, reads in rows to string vector and returns vector vector<string> get_mol_file(string& filePath) { vector<string> mol_file; string new_mol_line; // create an input stream and open the mol file ifstream read_mol_input; read_mol_input.open( filePath.c_str() );
[Code] ....
The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc.
