C++ :: Eliminate Comma And Split String Into Individual String Variables
Nov 15, 2013
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'm trying to right the function that puts the correct letters in the right positons being reported from my previous compareletter function for my game of hang man and its not updating the word in progress array. Here's my compare letter function that's working correctly:
Code: //function that returns the index of the letter that the user has guessed or Code: //-1 if the letter isn't in the word int CompareLetter(char array[], char guess, int numLetters) { int i;
[Code....
However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.
Ok, so I'm writing this code and when I build it keeps saying cannot implicitely convert type int to string even though I declared my variables as string. Why is it giving me this error?
private static string Repair() { string result=""; string beep; string spin; Console.WriteLine("Does your computer beep on startup?:(y,n)");
In my program, I am fed a string that contains integers such as Code: *str = "45678" and my program is simply supposed to read the number in and store each given number in a separate spot in an integer array. So basically, when my program has finished running it should be stored like:
however, this just seems to return an impossibly high garbage value when I do. I'm assuming the way I'm trying to store it is 'illegal', but I cant seem to find online a proper way to do it.
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.
Trying to append a comma to a string. Getting "Segmentation Error" on Solaris when the function is entered the second time.
Code:
// Appends a comma to the given string void appendComma(char* instring) { if (instring == NULL) { instring = realloc(NULL, strlen(",")); strcpy(instring,",");
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;
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?
I am wondering about the constructor. I see there appears to be nothing inside of TinyGPS::TinyGPS() as far as parameters go and that that declaration is followed by a ":". First I'm wondering as to the meaning of the colon. As well with the variables defined after the ":" I see some "(0)" and I am wondering as well to the exact meaning of the "(0)". Are those variables being defined as parameters separated by ","?
I have an input file that contains any number of lines. Each line will follow the same structure. There will be 5 fields, separated by 4 commas. Fields 1 and 3 will be single characters, fields 2,4,5 will be integers. Example:
<A, 123, B, 456, 789>
I need to iterate over each line, parse out the fields, and capture each field value into a separate variables.
I need to find some sort of method to convert a series of char variables to a string, to be shown in a label. I've searched for two days and experimented myself just as long, and the closest I've gotten simply puts ASCII values into the string with the following command:
What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?
String s("Hello"); String t("There"); 1. s = s + t; 2. s += t;
so i got a project from my college to make a calculator including numerous things. everything was done but at the last moment my teacher refused the use of sin() function and asked us to make it manually and not use the sin() function. creating the new code. with a deadline of less than 24 hours. here is the part of code that needs the change, we need to eliminate the use of sin() function.
I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code: #include <stdio.h> #include <string.h> int main() { char str[100]; int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0; at the beginning of the code and then made Code: count = strlen(str); why wouldn't i have the same result? Is there a way to do it also?
Very new to programming, and I know that there must be another way on inputting a string into each array cells not by just inputting it one by one, but as a whole. My code at the meantime is: [URL]
I have problem with string compare. I want to compare the string user input with a string in binary. And I don't know how to do it. Problem in function login();Here is the code: And you also can download file in attachment too..
