Compilation is success full ,but i am observing that some junk value is there in the path variable. After Reaching If statement cursor went to final return statement ...
I intent to use this mechanism for rename the file because the file name consists Unicode characters . I would like to know why the return value of "MoveFileExW" is false for file name consists 'space','hyphen' etc.(sometimes even without a Unicode character).for accepting 'space','hyphen' what type of conversion I would use [I.e.: Does the root cause of failure is due to CP_UTF8 type use].
Code:
//! inputPath & final_inputPath consist source and destination file name and are std::string //! Both are in same directory F: est_files std::wstring unicode_input_original; int unicode_input_length_original = 0
I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
I wanted to share the value of a variable from Sender Program to Receive after program and want to calculate difference between send and receive. After studying Header file concept I program following three.
Now I am struck. How to to compile? I link all these file. I used following method:
Then I run Sender and after that Receiver.I per my knowledge, Receiver should give difference but it gives error :
Code: Receiver.c: In function "main": Receiver.c:10:42: error: "Send" undeclared (first use in this function) printf(" Total Receive is %d ",Receive-Send);
Code: Sender.c #include <stdio.h> int Send ; void main(){
I have been working a project in C++. I have TTTMain.cpp file that has all the function calls, TTTFuntions.cpp that has all the functions, I have TTT.h file that has all the prototypes and variables and additionally I have Winner.h that has enum class Winner declaration in it. Here is my block of codes:
Winner.h file:
#ifndef winner #define winner enum class Winner {
[Code]....
My question is when I compile this gives me error on
I've been given an assignment with the below questions.
1. What is the difference between pass by reference & pass by pointers?
2. What is the use of the initialization list in the constructor?
3. What is meant by a reference & its advantage?
4. Class has a reference, pointer and a const. Is it possible to write the copy constructor & assignment operator overloading funciton? how? ( Since reference is there, I'm not sure on how to write for it)
5. Example for a variable decleration and definition? (I know for function but for variable don kw how)
6. static and const static what is the difference??
I made my header file. If cpp file with definitions is in project compiler knows it has to be linked, but if it's not compiler doesn't know. If I include standard library or boost I don't have to manually link cpps. How to do so including my header automatically links cpp? Maybe problem is with something else?I use VS 2013.
My socket.cpp program got error. it showed "socket.h: no such file or directory". I had put my header file (socket.h) in the same place with my source file.
This code is for fun, and have it doing a lot of what I want it to, just not all. I want random generated to write to a txt file. I tried to use an array but that failed. I wanted to use an array because i am only passing one value. Which makes sense since the random generated function is an int.
I made the fprintf as a comment but hopefully soon it will be able to send the values to the txt file. After that I will tackle the function.
Code:
#include <stdio.h> #include <stdlib.h> #include <string.h> #include <time.h> #define HIGH 49 #define LOW 1 int random_generated()
1. Write a program the calculates the volume of a sphere.
Use a define to set Pi to 3.14 and a macro for the formula for the sphere. V = 4/3PiR3. In main ask for the radius (R). Pass it to a function where you calculate the volume and return it to main and print the volume in main. Use float values. (Save this program as you'll need it later.)
I have a class Myclass (for the sake of the example). I have a header file 'space.h', which is following:
#include "Myclass.h" struct Files {Myclass* new_object, int number};
But turns out in the Myclass.h, I need the struct Files, like so:void function(vector<Files> arrangement);
So I would have to include "space.h" in the Myclass.h, but this way there's going to be a double definition of struct Files, since Myclass.h includes space.h and space.h includes Myclass.h.
I wrote a simple date class and could not get it to work until I put all the code in main(). Then it worked like a charm. I have not been able to create a separate .cpp file and get it to work with my existing main().
I tried to follow [URL] which is a closed article, with no success. I tried every combination I could think of and was unable to compile without error. (Linux Mint 17,code::blocks 13.12, G++ 4.8.2). I did finally get it to work by putting *all* my code in the .h file and #including the .h file (and nothing else) in the .cpp file. This is not how it's supposed to work.
This is unbelievable! I just tried this on another computer, same OS same version of Code::Blocks and G++.
