I wrote a binary function based on existing template:
template <class T> struct percentage : binary_function <T,T,double> {
double operator() (const T& x, const T& y) const
{return x*1.0/(x+y);}
};
I call it in form of percentage<int>() When I compile, it's indicated: error C2143: syntax error : missing ',' before '<' I use VC 2012.
i was working to compile the code below. Unfortunately it didn't compile and give me the known error error: attempt to use poisoned "calloc".
This is how i compile it :
gcc -I/usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5/plugin/include -fPIC -O0 -Wall -pedantic -std=c99 -c decode.c decode.o
decode.c

#include <gimple.h>

The below code compiles without error using VS 2012 but with g++ 4.1.2 I get this error:
Code:
main.cpp: In function 'int main(int, char**)':
main.cpp:37: error: no matching function for call to 'StringHelper::stringToNumeric(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
Here is the code:
#include <string>
#include "boost/lexical_cast.hpp"
using boost::lexical_cast;
using boost::bad_lexical_cast;
class StringHelper {
[Code] ....
This is part of a larger program so in reality StringHelper has more static functions but this example does produce the error the same as the code when in the larger program.
To get it to compile under g++ I had to assign the return value from substr() to a string and pass that string to stringToNumeric. Why do I have to do this for g++ and not VS? Do I have something wrong with my template function that g++ is calling out and VS is not?
I am trying to implement the insert function of a binary tree. Atm when I try and insert 3 nodes, the program breaks and gives me a stack overflow error. The error points to a getter function for an identifier for the data in my node class.
void LinkedList::add(Product *myProduct) {
if (_length==0) {
_head = new Node(NULL, NULL, myProduct);
_end = _head;
_length=1;
[Code] ....
Here is my insert function, the error message is
"An unhandled exception of type 'System.NullReferenceException' occurred in SDI2.exe
Additional information: Object reference not set to an instance of an object. "
In my main I have declared an instance of product, "productToAdd = new Product(id,idPrice);" so I'm a bit confused as to what I need to include..
what can i do to fix ? why do i get the error ?

View 1 Replies View RelatedI am trying to compile some code under opensuse 12.2. The code compiles fine under cygwin and CentOS. Under suse, I get the error "directory name must immediately follow -I"
This is the place in make where the error happens.
Code:
g77-3.3 -I ./src/src_common_depend/ -O2 -DVERNUM=6 -c -o bld_dir/FortranA.o src/src_client_main/FortranA.FOR
f771: error: directory name must immediately follow -I
The includes are specified in the make file with,
SOURCELOC = ./src
INCLUDES = -I ${SOURCELOC}/src_common_depend/
These are common includes that are used by more than one applications and so are stored in a common location.
I have tried leaving off the ./ and the trailing /
SOURCELOC = src
INCLUDES = -I ${SOURCELOC}/src_common_depend
And various similar combinations, including parenthesis instead of the curly braces.
I'm not sure why gcc under suse would be particular about this syntax when gcc under other distros seem to think it's fine.
This is the compile rule that g77 is implementing where the error occurs:
# compile src fortran objects with fortran preprocessor
$(BDIR)/%.o: $(SOURCELOC)/src_client_main/%.FOR
$(FCOMP) $(FCFLAGS) $(VFLAGS) -c -o $@ $<
I am working on a project, where I have to be able to exclude some code fast and dynamicly at compiletime.
I got a scheduler running and actually I just want to remove some of the tasks from it - but at compile time so that the code wont take up space in my microcontroller.
I know that I can use macros like #ifdef #endif etc. But I think that method makes the code unreadable and complicated.
How to archive such functionality a more elegant way?
I am trying to make a program like a virtual machine, and therefore I need to have a virtual hard drive. I have it split across four files, each being exactly 67,108,864 bytes (at this point, the files consist of 0x00 throughout the entire file). When I try to write to the beginning of one of the files, I get a "EXC_BAD_ACCESS (code=1, address=0xff)" from Xcode.
Here is my source code.
Code: #include <iostream>
#include <fstream>
using namespace std;
int main()

Objective of this program is to read binary data from a file and print it.
Code:
#include <stdio.h>
void readFile(void);
int main(){
readFile();
return 0;

But When I Run This Code First It Print "Error." Then Rest Of The File.Say In My File I Have "I AM HUMAN", It Prints "Error. HUMAN"!!
I Cant Figure Out Whats Wrong In The readFile() Function.It seems right to me.
I'm writing a binary search tree program and I got it to compile but as soon as I input something it returns a "segmentation fault error" . I suspect the issue with the code is withing my `add` function.

Node<T>* node = new Node<T>;
node->setValue(value);
m_root = node;

I have written a function that inserts and prints a binary function correctly.
For example a tree like this [URL] ..... would print like this

Here is my print function
Code:
void prt_tree(struct node *tree) {
if (tree == NULL) {
printf("Null Tree

Could I just make some adjustments to my function to reverse it? and if so, how?

One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.
I have a problem with the C code . I created two functions, one that runs through the tree inorder, the other that returns the maximum value in the tree. The problem is when I use in the main the method "max", which goes in a loop and not print anything on the screen . If I remove the call to method "max" it works fine. Here's the code:
Code:
#include<stdio.h>
#include<stdlib.h>
#define bool int
/* A binary tree tNode has data, pointer to left child
and a pointer to right child */
struct tNode {

I have written a function that takes in a positive decimal and returns its Binary equivalent; however, the output always adds an additional zero to the binary. What could I do to get rid of it?
If the number is 7, it outputs 0111 instead of 111.
Code:
#include <stdio.h>
void Dec(int n) {
if(n > 0)
Dec(n/2);

I am having trouble writing an insert function for a binary tree.

struct bt_ *left;

I am having an issue when i try to delete a node with 2 children it either doesn't delete anything, or wigs out in various manners deleting the wrong node or replacing a node with a various memory location. As follows, here is the delete function:
void BST::dele(){
bool found = false;//initialize a bool type to "find" the element to be deleted
if(root == NULL) return;//well if the tree's empty, nothing to be found right?
current = root;//set the current to the root to traverse the tree in search of the element
node* parent;//create a parent node for use once the node has been deleted
while(current != NULL){//traverse the tree

What is the difference between the two functions below? I created the function in the top and my friend created the function in the bottom. I just want to know why the function with the while loop prints the binary numbers backwards. And the recursive function prints the binary numbers correctly.
void findBinary(int num) {
int remainder = 0;
while ( num > 0) {
remainder = num % 2;
cout << remainder;
num = num / 2;

I had an assignment that I completed and it was just inserting values into a binary tree and then displaying it. I was wondering what the code would be if I wanted to delete a number in the binary tree, or if I wanted to search for a number. Here is my code for my assignment.

#include <stdio.h>

typedef struct bt_{
