Im using a recursive function to sort array. The decrement operator is used to eventually get to base condition in function. Used debugger the size-- expression is not decrementing. I figured out how to fix it but dont quite understand it.

One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.
Code:
void CFileManager::SplitHeader(std::string sFilePath) {
std::string sDrive(255, ');
std::string sDirectory(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

I am new to C programming and I am trying to compile and run an exponent program my instructor posted for us but it is giving me an error saying:
Warning c4550: expression evaluates to a function which is missing an argument list.
Why this is happening (she doesn't seem to find anything wrong with the code). From what I could gather there is some issue with the math but idk. It is supposed to prompt for the number and the exponent to raise it to, then calculate and output the result.

#include <stdio.h>

Implement a recursive function named void printBack(DoublyLinkedNode<T>* node) for the class DoublyLinkedCircularList which will print out the elements in the list from back to front. The function is initially called with the first node in the list. You may not make use of the previous(prev) links
This is my solution where I got 2 out of a possible 3 marks:
template<class T>
void DoublyLinkedCircularList<T> :: printBack(DoublyLinkedNode<T>* node) {
if(node->next == NULL) //Correct- 1 mark
return 0;
else
printBack(node->next); //Correct - 1 mark
cout << current-> element << " ";

Hey I am trying to use the getline() function to read a line from a file. For some reason Visual Studio 2010 gives me the following error. "No instance of overloaded function "getline" matches the argument list". The piece of code that produces the error is in a class in a separate .h file and is executed as a method of the object. I'm almost certain it has something to do with either the compiler thinking I am calling another getline in a different namespace or my parameters for the function are incorrect. Here is the code:

#include <iostream>
#include <string>
#include <vector>

I'm writing a program in C that performs operations on an array of 4-byte unsigned integers. Here's some usage examples:
+ n m // print sum of elements at indexes n and m
& n m // bitwise and of elements...
< n m // shift element at index n by m bits
I will have to implement functions for sum, bitwise-and, bitwise-or, xor, left-shift, right-shift... All with the same function format:
void print_operation(unsigned n, unsigned m) {
printf("%u
", n some_operator m);
}
Is there any way that I can pass an operator as an argument so that I can have a single elegant function that looks like this? I'd really like this to work like callback functions.
void print_operation(unsigned n, unsigned m, some_type oper) {
printf("%u
", oper(n, m));

i've just started learning building structures in c++ and they gave us an exercise of writing a recursive merge code of linked lists - just merging without sorting... i don't even know how to start this is how i started so far.... i know that the break in the recursive function is when i get to the end of the first list and then to start linking the second list..as you can see i wrote a function that uses recursive function...
LIST merge3(LIST lst1, LIST lst2) {
LNODE* curr1 = lst1.head;

I am having trouble modifying a linked list. I am writing a function to delete the last node from the linked list, but it gave me incompatible types error.Here is my struct:
Code:
typedef struct PCB{
int id;
struct PCB *next;
struct PCB *prev;
}PCB_rec, *PCB_p;
Here is my function to delete the last node (given the pointer is pointing at the last node of the list):
Code:
void del_last_node(PCB_p *process_list){
PCB_p temp = process_list;
if (temp->prev != NULL){
temp = temp->prev;
[Code] ....
And here is how I called the function:
Code: del_last_node(&process_list);
It gives me the following errors:
initialization from incompatible pointer type at line:
PCB_p temp = process_list
assignment from incompatible pointer type at line:
process_list = temp
You need to write a permute class that will take first and second strings to rearrange letters in first, followed by second. For example, if the first is “CAT” string and second is “MAN” string, then the program would print the strings TACMAN, ATCMAN, CTAMAN, TCAMAN, ACTMAN, and CATMAN. The first and second strings can be any length of string or a null.
The permute class uses a Note class as link list note to link all letters arrangement. The permute class has Note pointers, firstNote and lastNote, to point to the beginning and ending Notes of the link list as private data members. There are three other private data members (total, firstString and secondString) to store the total possible number of arrangements and strings pass into the class.
Write a driver to test the permute class to pass in any two strings of any sizes.
Other than mention in the following, you can add more classes, functions, and private data members to this program.
Note class
The Note class needs to have two private data members and a constructor. The two private data members are data and p pointer. The data’s data type is string and p pointer is Note. The Note class constructor has two parameters, one is string and the other is Note pointer.
Permute class
The Permute class has five private data members (*firstNote, *lastNote, total, firstString and secondString). The firstNote and lastNote pointers are point to Note. The total has integer data type. The firstString and secondString have string data type.
There should have at least three public member functions, Permute, permutation and print. The Permute function is the constructor which takes strings to initialize the private data members. The permutation function does the recursive call to arrange the strings and setup the link list. The print function will print out the private data member information.
Driver file
The driver file should declare a Permute eight elements pointer array. Instantiate eight Permute object with the following eight set of data and assign the object to the pointer array. Use a repetition to call the object’s print function to print out the private data member information. If the total of the permute private data member is less than 100 then print out the permutated letters four in a row, otherwise print out 9 in a row.

first = "", second ="CATMAN",

How to pass an int that I got from user input into a function to use it. I am trying to print out the words to a string of numbers.
I got the input from user.
I got an absolute value of the input.
I then separate the string into individual digits and name them.
I can print these out.
Then I started my if statement by checking if the original input was zero, and if it is, printing zero and exiting.
Then I an trying to pass the digits into a switch function and this is where I go off the rails.

I was reading about void as function argument, but I did not fully understand it's meaning in C.
In C++
void foo(void) {}
and
void foo() {}
are the same. It means no arguments for foo function. But in C it's different. First function means the same as in C++, but second means
In C, an empty parameter list means that the number and type of the function arguments are unknown. But if it is unknown you can't use this arguments if user specifies same. Because here are no variables to store them. So doesn't result are the some? You do not get any arguments. O do I can get this arguments from some hidden variable?
For example.
void foo() {
printf("%d", var);
}
foo(5);
It is very unclear for me. Do this apply to main function too?
int main(void)
int main()
or can I use arguments given to int main() like given to int main(int argc, char* argv[])
