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) {
int num;

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 am C++ newbie.
I want to ask how can i convert string to int and split it?
Like given string input is 00;
I want it to become 2 int which is 0 and 0...
I need to split my main() function into two separate functions.Where would the best place be to split it up?
* Read a text file whose name is given on the command line, and for each word:
* if it is an integer, insert it into an array in sorted order
* if it is not an integer, insert it into an array of words.
* Notes: converted to use C++ strings, because C strings are messier.
* Need to grow arrays, need to insert in sorted order.
* Growing arrays might be done the way we grew a C string:
* bigger = new <type> [size+1]
* for(i=0; i<size; i++) {
* bigger[i] = oldarray[i];

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 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?
What if I want to let the user know the number of trials left...? Like "2 attempts left", "1 attempt left"?...
View 1 Replies View Relatedi want to split the array into sections of 2 values, recursively. the objective its to do the average.i have this input and output, that its correct:
> media_recursiva a 1 a 2 a 4 a 5 a 2 a 3 a 5 a 6
1.000
1.500
3.000
3.500
("a 1" means add the value 1)
but mine its wrong, it gives to me this:
1.000
1.000
2.500
3.000
Code:
float media(int arr[], int count) {
while(count != 0){
if(count==1)
return arr[0];
else if(count ==2){
return ((arr[0] + arr[1])/2);

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"

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";

I've a code which reads the Spotify windows in order to get current song playing. The output is:
Spotify - SONGNAME
How can I remove "Spotify - " using split?
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 a list of date format 1-12-2011 that i get from a txt file.
char date[30];
fstream fin("date.txt");
fin >> date;
how do i split the date array to 3 array of char day[],char month[] and char year[] for my structure list? using delimiter '-' so i get 1 to day, 12 to month and 2011 to year.
struct date{
string day;
string month;
string year;
}
I am currently planning on splitting my image into 3 channels so i can get the RGB values of an image to plot a scatter graph so i can model is using a normal distribtion calculating the covariance matrix, mean, etc. then calculate distance between the background points and the actual image to segment the image.
Now in my first task, i have wrote the following code.
VideoCapture cam(0);
//int id=0;
Mat image, Rch,Gch,Bch;
vector<Mat> rgb(3); //RGB is a vector of 3 matrices
namedWindow("window");
[Code] ....
but as soon as it reaches the split function, i step through it, it causes a unhandled exception error. access violation writing location 0xfeeefeee.
I am still new to opencv, so am not used to dealing with unhandled exception error.
I tried adding items into the vector still error, either via push_back or general assignment i.e. rgb[0] = Rch or Bch still error.
I'm using the Split method to parse line in a csv file. The following code works if there are no commas in the text of my data.
string csvLine;
string[] splitLine;
csvLine = "Jim Borland,1234,Never dreams in code";
splitLine = csvLine.Split(',');
But if I have commas in the some of the text as below I get then wrong output. So I need split on a commas which are not enclosed in double quotes.
string csvLine;
string[] splitLine;
csvLine = ""Jim,C,Borland",1234,"Never dreams in code"";
splitLine = csvLine.Split(',');
The output I want is:
Jim,C,Borland
1234
Never dreams in code
I found this :
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.
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.
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.
View 1 Replies View RelatedI'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 had experience in programming from python (slightly related, html/css) and the computercraft from minecraff (basic i think it is).
My question is mainly about the C and past experience with the computercraft.
1. Is it possible to split the command console into 2 parts (a visual area and a text area)
2. Is it possible to use any form of pixel art or custom characters within any command console using C.
I trying to get input from the user and split into words that separated by a space.
string s = "1 2 3";
istringstream iss(s);
int n;
while (iss >> n) {
cout << "* " << n << endl;
}
The code above works fine but i want to get the string from user. the code below only prints the first word and trashes rest of the words in the sentence.
string s ;
cin>>s;
istringstream iss(s);
string n;
while (iss >> n) {
cout << "* " << n << endl;
}
i have to create a console based application in c language that can join and split bitmap images. the requirements of the application are as follows :
1. Split Image
Enter number of parts:
Enter source image path:
Enter destination folder:
2. Join Images (all images should be of same width and height)
Enter image path:
Join more Image (y/n):
3. Exit
Take care of following things:
- Application should show number of images processed while running.
- Acceptable Image format is BMP only.
- Application should give all the validations for correct image name, type, size, path, etc.
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.
