C# :: Split String With Boolean
Nov 19, 2014
I have my Arduino send the following string every second:
69.4,69.4,69.4,69.4,69.4,69.4,8.42,100,100,50,50,20,16,10,14
and i currently have my C# code split it and send the values to corresponding text boxes:
// SERIAL READS:
private void myport_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e) {
string RxData = myport.ReadLine();
this.BeginInvoke(new LineReceivedEvent(LineReceived), RxData);
[Code] ....
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 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.

I have the the following two strings:
D 1069 Dresden - Neustadt
01069 Dresden - Neustadt
I want to splitt the string and the result should be in both cases:
1069
Dresden - Neustadt
How could i do this with regular expression?

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"
[Code] ....

I manage to split this str = "abc,def,123"
to s1 = "abc", s2 = "def", s3 = "123" with this piece of code using find and substr.
string str, s1, s2, s3;
getline(cin, str);
unsigned pos1 = str.find(",");
[Code] ....
But what should I do if the len of the string is unknown ?
For example, str = "abc,def,123,ghi,jkl,456,mno" and so on...

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;

string totalString = "attack at dawn ";
int dimension = 3;

how to do this in C#. Need to connect to Oracle db, take a file from directory then read every line of the file. Lines are like this:
123234847656|8800359898818177|A|20130401 14:51:42|
123234847212||D|20130401 14:52:08|
123234847212||M|20130401 14:55:38|
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.

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?

is it possible in c++ to split string by string? And if yes, then how?
For example I have string:
one|#|two|#|three
I would like to split it by "|#|", not by one char.

If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.

#define GRAVITY 9.8
#define LIMIT 500
#define SEC 5

I made some research on how to negate a boolean value but none seemed to work. Ok, so I have the following code:
Code:
#include <iostream>
using namespace std;
int main() {
bool Turn = true;
for (int i = 1; i < 11; i++)
[Code]....
As of now the code prints "XXXXXXXXXX". And I want it to print "XOXOXOXOXO", so I tried 2 different things, which did not work:
Code:
#include <iostream>
using namespace std;
int main()
{
bool Turn = true;
for (int i = 1; i < 11; i++)
{
[Code]...
Code:
#include <iostream>
using namespace std;
int main()
{
bool Turn = true;
for (int i = 1; i < 11; i++)
[Code]...
Ok so I made those changes so that the boolean 'Turn' would change everytime the loop executed. Guess it doesn't work.

Let's say I have a product that needs service after 500 hours at 100 RPM. I can dsiplay the remaining hours only as an integer and we only have integer math. Management wants it to display 500 for the first hour, not 499 after the first minute is ticked off. But after a few minutes fullHours will be 499 and partialHours will have some value. I have 3 ways to determine displayHours to suit management and I want to know if the first is ligit.
short fullHours = 500;
short partialHours = 0;
short displayedHours = 0;
// Method 1 - Is is Kosher to cast a boolean as an int? Is TRUE always a 1 or is that a bad assumption?
displayedHours = fullHours + (short) (partialHours != 0);
//Method 2 - Works but some have disdain for the ternary conditional
displayHours = fullHours + (partialHours ? 1 : 0);
//Method 3 - seems a bit pedantic
displayHours = fullHours;
if (partialHours != 0) {
displayHours++;
}

Is the boolean function already defined under the default headers? Else, how would I create one? Would this work? :
#define true 1
#define false 0
typedef int bool;
Bool x=true;

i have a Boolean function containing 2D dynamic array, it'll retain either 0 or 1, how can i delete the dynamic array?
bool something (int** a,int b, int c) {
int **arr = new int*[b];
for(int i=0;i<b;i++)
arr[i]= new int[c];
if (...) return 0;

I'm working on a code that takes a number, splits them up and adds them.
For example:
I input 123456
my program will add 1+2+3+4+5+6 and print each number 1 2 3 4 5 6
I'm getting 2 errors
[Linker error] undefined reference to 'funtion(int)'
Id returned 1 exit status
Code:
#include<stdio.h>#include<stdlib.h>
void funtion(int x);
int main(void) {

Im using some motors which run off PWM pins.Theres a High byte and Loq byte register (PWMH,PWML).I have an int which i need to put into these registers but i dont know how???so for example
int:84 -> PWMH=0x00 , PWML=0x54
int:310 -> PWMH=0x01 , PWML=0x36
int:11588 -> PWMH=0x2D , PWML=0x44

I need writing a macro that would return true/false (1/0) )value. I want to check if a certain element exists in the array. The macro will accept array, its size, and the value to be compared, and must return yes or no. Here is the code that I have written:
Code:
#define EXISTS(T, a, n, val) do {
char ret=0;
T *a_ = (a);
size_t n_ = (n);
for (; n_ > 0; --n_, ++a_){
ret = (*a_ == val);
}
}
while(0)
How can I get the result from this macro.

Question for coding transivity in c++
a->b b->c then a->c
It should contain a main code reading from boolean matrix class. for ex)input file is
8
0 1
1 2
2 3
3 4
4 5
5 6
6 7
8 is the number of no.
what program should do.
1. check if 0->7 first(0th element)->last
2. check every 5th(5,10,15...) element is to last 5->7

I am writing a code where I have to find out the spot a letter is in. I am getting an error with assigning a function using a boolean operator.
bool is_member(const vector<char> & list, char character) {
for(int i=0; i < list.size(); i++) {
if(character==list[i]) {
return(true);
[Code] .....
My constant vector list is { 'a', 'e', 'i', 'o', 'u', 'y'}. My error comes in on line 20. I am not calling the boolean correctly. If I type in the letter "i". Then the function should output 2 since i is in the 2nd index spot of my vector list. How to fix my error? I am not understanding why my line of code is not working.

double coeffs[3];
double roots[2];

So I want to go from having 0 or 1 to having words like false or true. I did it with an if statement earlier today, but I had to get rid of the whole bool thing. I made the variable just a float. But he requires we use bool. Here is my code:
Car y;
cout << "Initial value for the Car: " << endl;
cout << "Age= " << y.getAge() << " years old. The Price= $" << y.getPrice() << endl;
y.setAge(8);
y.setPrice(12000);
y.setRaceCarStatus(true);
cout << "Modified value for the Car: " << endl;
[Code]...
I commented (//) the if statement that I had earlier. If I set RacecarStatus to True, is cout's 1. The starred (*) line right above the comments is the line that I was required to add. I want to cout the actual word true. The one I had this morning won't work anymore.
