For some reason my compiler says "rename not declared in this scope" .... Isn't it declared in iostream? Or is rename only for C not C++? And if it is only for C how do I rename a file in C++ then?
#include <iostream>
#include <cstdlib>

using namespace std;
int main()
{
do {
......sushi go;
......string x; <----------------------------Declared x here
......cout << "wanna use a banana?" << endl;
[Code ....
Error reads: 'x' was not declared in this scope.
How do I fix this?
P.S The sushi class does not matter, that is all perfect. Also, the dots are to represent my tabbing to make it easier to understand.

I'm working through this neural network tutorial, unfortunately I get stuck trying to compile on line 28, saying "error: 'neuronNum' not declared in this scope." I seem to always get stuck on these kinds of errors, yet I don't understand because I though that the variable was declared and initialized within the for loop.

I'm trying to make a dynamic 2d array of a Tile Object I created, the Dynamic 2d array was working when I tested it as an int array but not that I gave it a type of Tile it is giving me the above error. I'm reading values from a .txt .

I am trying to make a linked list. When I compile my code, I get an error saying 'current' is not declared in this scope. I don't understand because I have declared in the first line of my functions body. The variable is local to the function so I don't understand what the problem is.
#include <iostream>
#include <cstdlib>
using namespace std;

Are there any situations to explicitly use the scope resolution operator with global scope? I can imagine a situation like:
#include <cmath>
class IntWrapper{
public:
IntWrapper& pow(char);
IntWrapper(char);
private:
int m_int;
[Code] ....
But then I would think that the writer should have used a different name, and that using the scope resolution operator in the constructor body is still pointless...
struct x
{
y *GetY(); //error: what is "y"?
struct y
{
};
};
Why does GetY have to be declared after struct y is declared? I thought order of class members in C++ did not matter? Does it have to do with the way parsing is done?
EDIT: It also doesn't work if I typename x::y *GetY();, which makes even less sense to me.
EDIT: It works if I forward declare, but this goes against everything I know about C++ classes...
I want to rename all files in a folder (exactly I want to change extension file example:"FILE0001.CHK" to (FILE0001.JPG)), i know rename function , but how to use it all files, files names going sequencely (FILE0001.CHK,FILE002.CHK until FILE3000.CHK) ... How i can rename or change extension file quickly and easily.
View 1 Replies View RelatedI used rename function to rename a file.
The file names are in std::string type variable.
The function usage is like this
int result = rename (old_file_name.c_str(),new_file_name.c_str());
I expected result = 0 but i get result = -1.
Does this return code is due to any file pointer holding to this file?
How to rename a textfile in a Visual C++ CLI GUI project. I've tried using the 'rename()' function but that isn't working for me (probably because of the type of project).
View 2 Replies View RelatedI am having a datagrid view. In that suppose I give the header name as wrong, suppose say, instead of "test", i gave it as "tst". So i need to rename in this case. So what i expect is I need to double click that header and rename it. But in code I can't directly give it as "test", since it can be whatever. By double clicking i need to change in that display itself. I can able to catch the double click event. It is as below. Any code which makes me to edit and rename the header.

My source works perfect.The problem is that the (remove(),rename()) functions works but return nonzero number, so they fails all the time.

I need a code for renaming multiple(bulk or all ) files in a folder.
I found one batch file script but it renaming with numbers only. But i want differntly.
[URL] .....
Example:
In a folder there are 100 images and all numbered with some digits or names.
assume that all images are belongs to "john" , so i want to rename all images with "john+ a random string".
here a random string means -> it has an array with 3000 english words, (you can predefine them by downloading from dictonary).
In the script the 3000 names are fixed, but the 1st name will be changed by my wish. that my be john, mary, sai, pavan etc...
Suggestion: you do not need to enter all 3000 words in array manually. some javscript codes are there to read input of each and evey line and them into an array.
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 this code to check if file exist already and its work, but what i need is : is to add feature to function to see if the file already exist open same file and rename it with another name ,probably file2
assume file name is "abc.c"
This scenario like this
User>>(provide file name)
Code>>(check if file already exist show msg:
"File already (abc.c) exist would you like to create another file and rename it ("abc2.c") "maybe it need loop to search directory "????
User>>if press yes ok it will make another file with another name but if no exit the function and dont create another file
Code: // function to check file existence and here what i need to add the feature above
int fExist(const char* fn){
struct stat buffer;
int exist = stat(fn,&buffer);
if(exist == 0)

Did a little Googling on this but couldn't find anything definitive. Is it safe to do something like
Code:
void MyClass::myFunc(){
my_type_t &foo = some_obj->get_member_reference();
store_for_later(&foo);
}
Then at some pointer later in execution, another function uses the pointer passed to store_for_later.
I have done alot of googling for the scope resolution operator and Ive gained a bit of an understanding as to what it does i know it can distinguish between global and local variables, but I see it used to access methods/members of classes such as this example, why not just use a dot instead to access it?:
sql:: Driver *driver;
Why is the scope resolution operator being used here?
The situation is the following :
Code:
vector<int>& function(int a , int b){
vector<int> s(3000000);
vector<int> xxx(4);
return xxx
}
Not to board people with details but if i am returning the the reference to a vector xxx what happens to vector s. is it destroyed ?? it should be, but i don't see it on my memory map (memory is not released) . can this be or should i go and search for error on some other place.....
Can we use using declaration within name space scope? is it safe to use it?
I think we can use using declaration for class scope and function scope only.

I am retrieving the data by using above code
From some other code i am calling some function in c# through windows service. That function is going to delete some unwanted data from sql server database. if i wanted i initiate the request it will take 30 min to delete the data.
in this 30 min time i am unable to access other pages in my website. is there any better way to design this?
Ran into something today that does not make sense:
This compiles: Code: int x = 5;
switch(x) {
case 0:
{
int value = 5;
}
break;
[Code] ....
Ok so it doesn't like int value = 6 b/c of int value = 5 for case 0. However since the value in case 0 is declared within the brackets one would think it has case scope.
So I tried this:
Code: int x = 5;
switch(x) {
case 0:
{
int value = 5;
}
break;
[Code] ....
Now it doesn't like it b/c value has not been declared in case 1:. These two conditions cannot possibly be both true at the same time. You cannot disallow the declaration of value in case 1 b/c it interferes with value in case 0 and at the same time disallow me to use value from case 0 b/c it is not in scope. If it was not in scope then theoretically I should be able to declare value in case 1.
Both MSVS 2012 and 2013 exhibit the same behavior. I checked the standard and it is unclear on the matter.
