Visual C++ :: Circular Buffer - No Instance Of Overload Function Matches Argument List
Nov 25, 2014
I'm having some issues with my code. For the produce function i am getting an error saying 'no instance of overload function produce() matches the argument list' and also for the lines buffer[head].data = message; buffer[head].time = current_time i get an error saying 'expression must have pointer to object type.
In the code i'm not sure if i passed the variables to the function correctly. I have attached the code .....

These are the two errors I get...

Code:
void CFileManager::SplitHeader(std::string sFilePath) {
std::string sDrive(255, ');
std::string sDirectory(255, ');
std::string sFileName(255, ');
std::string sExtension(255, ');
_splitpath_s(&sFilePath[0], &sDrive[0], sDrive.size, &sDirectory[0], sDirectory.size, &sFileName[0], sFileName.size, &sExtension[0], sExtension.size);
}
Which gives me error
Error 1 error C3867: 'std::basic_string<char,std::char_traits<char>,std ::allocator<char>>::size': function call missing argument list; use '&std::basic_string<char,std::char_traits<char>,st d::allocator<char>>::size' to create a pointer to member.

The code below outputs this:
a[]= 00
a[]= 10
a[]= 10
a[]= 10
a[]= 11
a[]= 11
0.
But I was expecting this:
a[]= 00
a[]= 10
a[]= 10
a[]= 00
a[]= 01
0.
This describes how the process is running in machine:
1. Defining a[2]{0,0}; ii=0; aj=0
2. Calling function func(a,ii,aj) |func({0,0},0,0)|
3. func({0,0},0,0) defining w=0; static aa=0
4. func({0,0},0,0) if(0) returns aa=1
5. func({0,0},0,0) for j=0
6. func({0,0},0,0) for Outputing "00", because a[2]={0,0}, look (1).
7. func({0,0},0,0) for if(!0) | because a[0]=0| returns w+=func(a,ii+1,j) |func({0,0},0+1,0)| and calls func({0,0},1,0)
8. func({0,0},0,0) for if func({0,0},1,0) defining w=0
9. func({0,0},0,0) for if func({1,0},1,0) if(1) returns a[0]=1, because of static aa=1, см 4.
10. func({0,0},0,0) for if func({1,0},1,0) for j=0
11. func({0,0},0,0) for if func({1,0},1,0) for Outputing "10", because of a[2]={1,0}, look row #9
12. func({0,0},0,0) for if func({1,0},1,0) for if(!1) |because a[0]=1|
13. func({0,0},0,0) for if func({1,0},1,0) for j=1
14. func({0,0},0,0) for if func({1,0},1,0) for Outputing "10"
15. func({0,0},0,0) for if func({1,0},1,0) for if(!0) |because a[1]=0|
16. func({0,0},0,0) for if func({1,0},1,0) for if if(1==1) |because ii=1, func({0,0},ii,0)|
17. func({0,0},0,0) for if func({1,0},1,0) for if if return 0
18. func({0,0},0,0) for if w=0 |because func({1,0},1,0) gives 0|
19. func({0,0},0,0) for j=1
And from now, something is happening that I cannot understand:
20. func({0,0},0,0) for Outputing "10"
Why so? If func has itselfs local variables, including a[2]={0,0}.
I was expecting this:
20. func({0,0},0,0) for Outputing "00"
So a[2] array is not local variable. Why it happens?
Code:
#include <iostream>
using namespace std;
int func(bool a[],int ii,int aj) {
int w=0;
static bool aa=0;

I have a very strange problem with the system() function (on XP).
I have the following code:
Code:
char *text1 = ""A SpaceAction.bat" fred";
char *text2 = ""A SpaceAction.bat" "fred"";
int main(int argc, char *argv[]) {
printf("%s
", text1);
[Code] .....
When I run it where "A Space" is a directory with a space in the name, this is the result:
Code:
"A SpaceAction.bat" fred
F:Test>echo Testing
Testing
"A SpaceAction.bat" "fred"
'A' is not recognized as an internal or external command, operable program or batch file.
It seems that the double quotes round an argument make the parsing of the command fail.

The program use a circular linked list and data structures to store the tasks.
- Every task should include a task name, a name for the person assigned to it, and the deadline for the task.
- Variables should be dynamic and their sizes should be determined at runtime based on the length of user input.
- You should implement the following functions (with appropriate arguments and return types) for your structure: add(), remove(), search(), and list().
- The add()function should add tasks alphabetically by task name. You do not need to implement any file operations.
- The search() function should be able search for a task by the task assignee name or the task name.
- The list() function should print records to the screen in the order they appear in the circular linked list.
- You should successfully deallocate all of the allocated memory before termination of your program.

I am having one issue with my project. We are making a game of Nim code.I'm 99% done with it, i worked hard on it and i feel like i did a good job, however my project is not displaying the matches i want. For example, it display's the inital number of them 23. But once the first player subtracts a number, it doesn't display matches for player 2, just the number of matches remaining. Then as i keep running the program the same thing happens. This is what it's supposed to
output:
"Input/Output sample
WELCOME TO NIM
------- -- ---
Enter the starting player's name (no spaces)-->John
Enter the second player's name (no spaces)-->Mary
There are 23 matches.
ooooooooooooooooooooooo
|||||||||||||||||||||||
Player John please enter the number of matches to remove-->2
There are 21 matches.
ooooooooooooooooooooo
|||||||||||||||||||||
Player Mary please enter the number of matches to remove-->3
There are 18 matches.
oooooooooooooooooo
||||||||||||||||||
Player John please enter the number of matches to remove-->1 "
This is entire code.
#include <iostream>
#include <string>
using namespace std;
int main() {
// Holds variables.
[Code] ....
I will attach my code as well.ProjectNim.cpp

I have a .cpp file which contains 5 smaller defined classes. In my missile class I have a default constructor and a constructor that I invoke
class Missile{
private:
bool isHuman;
[Code]...
My issue is when creating and adding the pointer object; it doesn't seem to create a new instance of the class-the Missile objects all share the same xPos value which is always the first xPos when the "fire" command is given. The "Missile *missile = new Missile(xPos, yPos, true);" line does not seem to create a new instance of the object with different variables but instead creates a new object with the same variables. Is it necessary for me to always make a separate .cpp and .h file for any class I want to create multiple instances of or can I keep the smaller classes in the same file and still create a new separate instance of the class?
