I have lots of files needed for program named text1,text2, etc. I tried to do a loop like this:
ofstream of;
for(char i='1';i<'9';i++)
{
of.open("text"<<i<<".txt");
}
I tried without << too, but it doesn't work neither. How can I make it work, without writing a line for each operation?

I have a file path in a wstring like this:
wstring pathName = L"c:windowssystem est.exe";
I want to be able to geta new wstring that just contains "test" from this wstring.
How can I do that?
Code:
#include <stdio.h>
void ASCII_to_EBCDIC( size_t, unsigned char *);
void EBCDIC_to_ASCII( size_t, unsigned char *);
void to_ASCII(unsigned char *);
void to_EBCDIC(unsigned char *);

static unsigned char

I compile this with no problem, but gives "File could not be opened". the strcmp tells me name and "snazzyjazz.txt" are not equal. but when I print them I get the same output.
So. I have a CSV Parser that I built. It works very well. The way it currently works is that I have the parser in a header file "CSV_Parser". So my .cpp code would look like this:
#include <iostream>
#include <eigen3/Eigen/Dense>
#include "CSV_Parser.h"
using namespace std;
using Eigen;
[Code] ....
This all works great. I am running Eclipse in Linux (Xubuntu to be precise). In the header file the .csv is opened as follows:
ifstream infile;
infile.open("/home/karrotman/Desktop/Matrix.csv");
What I would like is for the user to be able to change the file that the parser is opening through the main .cpp file. In other words, is there a way to create some variable, say "FileName" and do the following:
CSV firstMat;
string MatrixA = "/home/karrotman/Desktop/Matrix1.csv";
firstMat.extract(MatrixA);
CSV secondMat;
string MatrixB = "/home/karrotman/Desktop/Matrix2.csv";
secondMat.extract(MatrixB);
And then the .h would now say:
void extract(string FileName)
...
ifstream infile;
infile.open(FileName);
Obviously this does not work. Ultimately the goal is for me to open 4 .csvs at one time so I can do numerical operations on them.
I am trying to establish a connection between client and server to send a file to the server from a client. I have been successfully able to send files to the server but i am facing a problem with the the filename whenever i try to send any string to the server and use it in naming the filename at the server side, the string is successfully concatenated but it saves the filecontents in the filename.
for example: i am sending a file hello1.txt to server and the server has to save it as abcxyz.txt as i am sending the "xyz" from the client. BUT Whenever i am doing this ,the file saves as abcxyzfilecontents.txt If i saved in the .txt file "you123" ,my file at server side would save as abcxyzyou123.txt
Here are my codes:
Know that the server code implements a multi threaded server. The functionality to be discussed is defined in myfunc
Code:

I am wanting to have a text file which is named with the user input and appended with .txt.
cout << "Please enter a new filename for storing new coordinates in: ";
char name[50];
ofstream output;

output.open(name + ".txt");
Get an error with this code on ".txt".
I have written some c++ code in codeblocks but I am getting errors when i am trying to compile it. I have a file named files.txt and this file consists of the names of the files that actually contain the data that I need to present. I am trying to get the name of files from from once class and passing it through to another to process. These are the codes that i have:
main.cpp
#include <iostream>
#include <fstream>
#include <string>
#include "Files.h"
#include "Datafile.h"
using namespace std;
int main() {
ifstream infile("fileListAug.txt");
[Code] .....
The error message that i get is error: no match for call to (std:: string). For ther line with the error I have used (*******Error points to this line).
Code:
cout<<"Enter Filename for input e.g(inp1.txt .... inp10.txt):"<<flush;
cin>>filename;
ifstream inpfile;
inpfile.open(filename,ios::in);
if(inpfile.is_open())

I've made a code to check whether or not a save file has been created correctly, but for some reason it always returns this line: readdata[qa]=='1' as true. in which qa is the counter I use in a for loop and readdata is a character array consisting of 50 characters that are either 0, 1 or 2.
this is the entire code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
[Code]....
at first is also went wrong at line 22 and also returned that as true, but then I added brackets and it worked.
I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?
joe bob joe bob

By the way, how to implement "insert" and "heapify" and in insert, when we insert an element we also heapify it?
My program will ask the user to enter the number of lines for the sentence "I will always use object Oriented programming. " if for example, the user enters 3, it should print out
I will always use object Oriented programming. I will always use object Oriented programming. I will always use object Oriented programming.
the second part of my program asks the user to enter the line which we want to make a typo. If they enter 2, it will replace the "I will always use object Oriented programming. " with "I will always use object Oriented programing." in the second line.
this is how it should look like but I am having trouble putting the second part together. I don't know how to remove the sentence and replace it with the second part.
Enter the number of lines for the punishment: 6
Enter the line for which we want to make a typo: 3
I will always use object oriented programming. I will always use object oriented programming. I will always use object oriented programing. I will always use object oriented programming. I will always use object oriented programming. I will always use object oriented programming.

Make a C++ Program that will use nested if else and any looping statement to display the following a certain number of times depending on how many times the user wants it to do so.
Input Values:
1. Name of employee
2. Position in the company
3. No. of hours worked
4. Rate per hour
5. Overtime hours
Required Output:
No. Name Position Rate per No. of hours Basic No. of overtime Overtime
hour worked Pay hours Pay
1. Juan Manager 160 140 22400 10 2100
Computations:
basic pay = no. hours worked x rate per hour
overtime = overtime hours x 150% of rate per hour
Just asking how can I input the name, position, rate per hour, overtime hours and hours worked in a horizontal manner?
Because I need to achieve the required output.
