I'm new to C and encountered a weird problem. Here's the code:
int main(){
char name[]="";
readname(name) ;
printf("The filename is: %s
",name);
printf(name);

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.
how I would code copying a file that cannot be opened (eg. any file that isn't ANSII format).
I know that for a .txt or something like that I could simply do
#include <iostream>
#include <fstream>
#include <string>
[Code].....
how I would copy a file's contents into a char buffer and copy it over to another file for files that can't be opened/read in notepad? (Example: a rar file or a .exe ) Not sure if that makes

I am getting a few compile errors for what might be a simple thing to do. I am opening a file in main, passing that pointer to a function and checking the contents of that file with a regex before I pass it on to build a BST. I am getting the following compile errors, what is wrong. Here are the errors:
Code:
gcc main.c fileCheck.c -o tree

main.c:19: error: syntax error before "FILE"

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

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;
cin.getline(name, 50);
output.open(name + ".txt");
Get an error with this code on ".txt".
I' used to check if my streams are properly opened with a simple:
Code:
if (!file)
std::cout<<"Error message";
However I just realized this is only a valid test if they are initialized with a wrong string and when I tested it:
Code:
int main() {
ifstream f_one("input.txt");
ifstream f_two("not_a_file.txt");
ifstream f_three;
[Code] ....
I didn't get the f_three error message, only the f_two.
how should I check my streams in order to prevent this?
this is the code:
Code:
#include <stdio.h>
#include <string>
#include <iostream>
using namespace std;
int main () {
int result,i,j;
[Code] ....
and it doesn't find it. it says the the word:"Users" is incorrectly formed universal character name ....
I have a file path in a wstring like this:

How can I do that?

So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;
int progfiles() {

This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer
i
c
i
Press any key to continue . . .
The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output
"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"
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.
What would be the correct way to call a function within main that has file pointer parameters?

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

int main() {

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).

-10^9 <= a[i] <= 10^9
1 <= x <= 10^18
and 1 <= n <= 10000
Every value here is an integer value

Okay so I thought I had this assignment completed properly last week. Last night I found a bug while playing the game.why won't the game end when the player guesses the correct number? The game allows you to finish using the max number of guesses even though you already guessed the correct number.
Code:
#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#define MAXGUESSES 6
#define MAXGAMES 20
#define MAXNUMBER 100

I have a program that printf a float that is returned by a function like this:
Code:
printf("%3.1f
", myfloat());
...
float myfloat(void) {
code....
}
In w32 my program has been running ok, but when run in a w64, it crash at the printf. If I change the definition of the function to return double it runs ok. in printf format string - Wikipedia, the free encyclopedia , in the "type" section I see there is no definition to print a float, but %f is for double in fixed point.So the question is what is the correct way to printf a float? must I cast? or is it better to return double? if so, does it have a performance penalty?
Well... I observed, as a non-professional programmer that "overloading operators" has some strict rules and some conventions... so any operator can differ from another. In order to have a clearest idea, I'd like to ask you to specify, for every operator, the correct (or best) way to overload it.
There are cases where you define &operator and cases where you define operator (without "&"). There are cases where operator are defined as "friend" inside class, and other cases where operator is declared externally.
example: ostream &operator<<
(why it uses & ??)
So can we have a summary for all kind of operators?
#include <iostream>
#include <string>
using namespace std;
void secondq();
void thirdq();

I have programmed a game where you guess a number (1-6) and if the number is equal to the random number then give the player score + 10. But if I have selected for example 4 players then if the game will give player 1 a score it gives player 2 a score instead? What can be causing this error?
