C++ :: Reading Series Of Strings Into Array Then Output

Feb 24, 2015

The requirement was to set the txt files information equal to a variable before and not to put it directly into the array.

#include <iostream>
#include <string>
#include <fstream>
#include <sstream>
using namespace std;
const int MAX = 24;
struct applicant_info {

[Code] .....

the txt doc looks something like this: file name: jobs4.txt

C/C++ :: Reading Strings To Char Array From Exe File

Feb 25, 2014

I am trying to read strings to an char array from an .exe file and then i would check some of the strings, but the problem is that the only thing that is read from the file is the first string (MZ) and an 'square' that is some incorrect character. I am using fread to read from the file. Here is my code:

FILE * pFile;
long lSize;
char * buffer;
size_t result;
pFile = fopen("my_file.exe", "rb");
if( pFile == NULL) exit(1);
fseek(pFile,0, SEEK_END);

[Code] ....

(I want to read the whole file, its not that big)...

C++ :: Creating Series Of Outputs Using Array Created By Variable?

May 18, 2014

I'm expected to get a starting minimum input, and also an ending maximum output (for example: 21, and 25). From here, i have to give output using all the numbers (in a row) between the min and max numbers.

(for the same example:
21
22
23
24
25)

I assumed I would want to create an array using a variable, but i'm not sure of that either.

C# :: Fibonacci Series - Adding Value In Array Inside While Loop

May 27, 2014

I am making a program to run Fibonacci series. I have created 2 array.

1)- 1st array holds only 0, 1
2)- 2nd array holds other values eg: 1, 2, 3, 5..........etc

I am using while loop to get the febonacci series and storing it in a 2nd array called int[] numbers.

After getting value using while loop, I am joing both the arrays using int[] final = arr.Concat(number).ToArray();

At last, I have used foreach loop to add the febonacci series into the listbox.

The problem I have is that, I cannot able to concat both the arrays. I tried to assign number array at the top of the while loop. so that number variable will be accessible outside the while loop. But I am getting a error.

See the code below

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

C++ :: Using Vectors And Strings / How To Output Name With Lowest Age

Nov 5, 2013

I have to write a program in C++, without using a selection sort, that outputs the name you enter with the lowest age. You input 5 names with ages and at the end it outputs the youngest person. This is what I have so far:

#include <iostream>
#include <vector>
#include <string>
using namespace std;
int main()

[code]......

I Know for the second for loop there has to be if statements in it but I am so stuck on what to write next.

C :: Reading Strings From File

Nov 2, 2013

It appears that when you enter command line arguments or use fgets() to input a string you can assign that string to another string variable using the assignment operator. But when you read from a file, you can't do that, you get a segfault. It seems the only way to get around that is to malloc the string and use the strcpy function.

Code:
#include <stdio.h>
struct person {
char *names[2];
};
void readFile(struct person p){
FILE *file = fopen("names", "r");

C# :: How To Use Confirmation Dialog When Reading Strings

Jun 11, 2014

Here's what I want to do:

So, basically the user imports a list of strings from a CSV file and the lines get read line by line and sorted in a listbox. If the user uploads the same file again that contains the same list of strings, a confirmation box with the following is supposed to be displayed:

"The list is the same. Are you sure you want to import this list of strings?" The options are yes, no, maybe.

If the user clicks on yes, all the strings get saved/put into the listbox regardless of whether or not they are repeated. No allows the user to to cancel the whole operation and return back to the screen for all samples. Maybe allows the user to individually pick which one they want saved or not. Maybe takes the user to a yes or no confirmation dialog box and it loops through all the strings in the csv file until the user has picked yes (accept) or no (deny). Only the confirmation box with yes and no should be looping.

What I have so far:

-Two confirmation boxes (I decided it would be easier for me to create two views and two viewmodels just for confirmation box setup - one with confirmation box of yes/no/maybe and one with confirmation box of yes/no).
-All the event handling is set and done.
-Reading the CSV file and checking for duplicates.
What I have problems with:
-When the call the confirmation dialogs...

Here's a snippet of what I have:

public void ReadImportedSamples(string filePath)
{
string line;
try
{
using (DDataContext context = new DDataContext())
{
using (StreamReader sr = new StreamReader(filePath))
{

[Code]...

So, I have two confirmation boxes, confirmationWindowSamplesListYN (only yes and no) and confirmWindowForSamplesList (with maybe).

Everything is set up fine. I am just wondering when the call the proper confirmation dialogs so that I can get the behavior above?

C :: Reading Formatted Strings From Text File

I wanted to improve the game from my last thread. I want to read and store a question in this format: Code: Who invented the BALLPOINT PEN?

A - Biro Brothers

C - Bicc Brothers
D - Write Bothers

But when I use fgets() to read the string, it reads all the ' ' literally instead of outputting a real newline. Like if it read the above question, I want it to print something like this:

C :: Reading Matching Strings From A File And Deleting From Another

Sep 26, 2014

We are generating emails for freshman students, however, the system probably due to server overload fails to generate some emails. So I'm working on this c code( probably was a wrong choice) to search for regexp matching the generated emails and deleting from the list of students and propective emails.

I"m currently at the stage of making sure the code can find all the matching regexp from the student list file before deleting! But the code fails to read all matching regexp?

Code:
//Filename: SearchReplace.c
//Usage: This searches for lines in a file containing a particular work and deletes the lines.
//Licence: GNU P.L.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

[code] .....

What I'm missing. It recognizes some regexp and fails to recognise some. Been staring for hours!

C/C++ :: Reading Strings From A Text File And Printing Them

Feb 26, 2015

I need a program that reads the number of lines of a file and then several (max of 20) lines of text from a .txt file so an example of the .txt file is: 2 This is the first string This is string number 2 So it first reads the 2 and then reads the two lines of text. It stores the text in an array of pointers. The code i have so far is:

#include<stdio.h>
#include<string.h>
#include<ctype.h>
#include<stdlib.h>

[Code].....

It doesnt give me any errors but all it does is keep running and doesnt print anything out kind of like its in an infinite loop although i dont see how that could be possible.

C++ :: Output Vowel From User Input - Error With Strings And Functions

Nov 25, 2014

The program is supposed to read in a string from the user and then output the number of each vowel that the string has. My first function is initializing the vectors, and the one that I'm having trouble with is the function used to read the string from the user and save it.

Here's my code:

#include <cstdlib>
#include <iostream>
#include <iomanip>
#include <string>
#include <vector>
using namespace std;

// FUNCTION PROTOTYPES GO HERE:
void init_vectors(vector<char> & vowels, vector<int> & frequencies);
string read_text(const string & prompt);

[Code] ....

And I'm getting the error:

freq.cpp: In function ‘std::string read_text(const std::string&)’:
freq.cpp:74: error: no matching function for call to ‘getline(std::istream&, const std::basic_string<char, std::char_traits<char>, std::allocator<char> >&)’

I'm not too sure if I can't use the function getline here or if there is something wrong with the function prototype itself but I'm pretty sure there isn't an error there as it was given to me.

C :: Reading And Printing In A Specific Format Strings Of Characters And Integers

Feb 23, 2015

I have been skimming and searching but dont know how to word the search just right to find what I need to know. I have written simple stuff with the support of tutorials like weight conversion or loops counting up to a set number. Nothing amazing. The other day I found out how to input and print a string rather than a single text character which i though was bad ass. I even got it to read multiple strings on a single line and found a way to read multiple lines. I can even format it to read both integers and characters on the same line as long as I know the predefined format.

On to my question... How do I read multiple lines with both carecters and integers. for instance:

nissan 1996
toyota 1998
or more comples like
nissan gtr 1996
toyota markii 1998

I want to use
int year;
char make[10]; maybe need to use char make[10][10]; for an array i would guess.
char model[10]; optional for the extra data

but reproduce what i read in a different order. say...
1996 nissan
1998 toyota
vice the original format.

this is what I have tried.

Code: scanf("%s %s", &make,&year);

//The way I seen to read multiple lines was on here

scanf("%[^/t]", %make);

But this wont let me separate the two into two differnet definded data types. Let alone use printf to display them in reverse order.

C++ :: Reading From Console Multiple Strings Of Unknown Length In Combination With Integers

Oct 10, 2014

I want to read a string of unknown length from stdin. I tried to follow the approach from this link.

[URL]....

My code is like this:

Code:

#include <iostream>
#include <string>
using namespace std;
int n;
cin >> n;
cout << "The value of n is " << n << endl;
string str;
getline(cin, str);
cout << "The entereed string is " << str << endl;

What I have noticed is that if I take integer input from cin (cin >> n in the above code before getline, the control does not stop on getline to take str as input from the console. If I don't do (cin >> n) before getline then the control stops on getline and takes the string as input.

What is the best way to read from console multiple strings of unknown length in combination with the integers?

C++ :: Opening And Reading Files With Input / Output?

Oct 15, 2014

I'm in a CIS 143 class which is Introduction to Programming using C++. We've been assigned a lab with little to no detail on how to do the things listed.

The purpose of this lab is to practice the file input and output concepts. For this lab you may assume that the input files exist and contain appropriate data inside of them.

Four separate text files* which contain the following lines, different for each file.

(*: This isn't on the lab, but don't worry about what the name, age, id, and major are. those can be random and I can just change them what they need to be)

Name
Age
Student ID Number
Major

Your program should ask the user which of the four input files they would like to open, and then read the contents from the file. Once the contents have been read in, it should output to both the screen and a file named "output.txt" the four values were read in, arranged as follows:

"Hello <name>! You are a <age> years old <major> student, and your ID number is <ID number>"

Now I am by no means saying "Do it for me". I just need to know how to have a user type file1, file2, file3, or file4, and then have the program open that file, then have the output.txt file arrange the wording into the sentence above.

This is what I have so far and I don't think it is anywhere near correct:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
ifstream inFile;
string file1;
string file2;

C :: Can Strings Fit In Array

Mar 5, 2013

1. I finished reading a beginning C book, and in the section about arrays, it says that one string can fit in a character array (char arrayname[]) but there cannot be a string array (string arrayname[]) that have multiple strings. Is

Code: string arrayname[4] = {"one", "two", "three"}; not valid?

My compiler lets me run it and it works, but why is the book saying it's wrong?

2. I know you can represent multiple strings in a character array by:

Code: char newarray[10][4] = ("one", "two", "three");

because [10][4] indicates that there should be four newarrays created with a max of 10 characters each, but is

Code: string multiplestrings[10][4] = ("i love you", "hello come to me", "i don't get C"; "hello world", "what are arrays"; "i am happy", "I am learning how to code"); valid?

Does multiplestrings[10][4] basically create 4 string arrays that have a maximum of 10 different strings within each string array?

C :: Array Of Pointers To Strings

Mar 6, 2015

I'm wondering how to access Buffer 1 and 2 via the pointer array;

Code:
char *BufPtrs[3];
char Buffer1[64];
char Buffer2[64];
BufPtrs[0] = Buffer1;
BufPtrs[1] = Buffer2;
BufPtrs[2] = NULL;

I thought that if I were to access Buffer1 via BufPtrs[0], I would simply just put an * to it before printf()-ing or store it in a char[] (equivalent to a string).
