I tested my count funtion. So my count function is not working properly, it should return 5 because 5 words have prefix "tal," but it is giving me 10. It's counting blank nodes.
This is my main.cpp file
int main() {
string word;
cout<<"Enter a word"<<endl;
cin >> word;
string filename;
[Code] .....
My program does compile and counts the number of lines of code, which is LOC: 20. My issue this, according to my code instruction it should not count comments (//) and also shouldn't count blank lines of code. Unfortunately my code is counting // and white space.
What seems to be working is #, all three includes are not being counted. That’s a good sign. I’m using the same technique not to count #. Why isn't working for comments and blank lines? I’m pretty sure that my logic is correct. I think my problem is maybe syntax.

I'm making some progress. My program does compile and output the number of line per code, but it shouldn't count comments and blank lines. I tried using (s.substr(0,2) == "//") as suggested but it didn't work.

#include <iostream>

I am trying to count every node of a binary tree internally (not passing in the root), all my attemps have ended in memory access violation or an inaccurate count (4 or 5) when it should be 10.
This is what I have tried
And yes I am NOT suppose to pass in the root.
int CountChildren()
{
if ( !Left() && !Right())
return 1;
if ( Left() )
return Left()->CountChildren() +1;
if ( Right() )
return Right()->CountChildren() +1;
}
or
int CountChildren()
{
if(!Left() && !Right())
return 1;
else
return Left()->CountChildren()) + Right()->CountChildren() + 1;
}
I'm trying to count the number of node in a binary tree. I have a public count function that calls a private count function. I keep getting a linker error: Undefined symbols for architecture x86_64:
"BST<int>::nodesCount(BST_Node<int>*, int&)", referenced from:
BST<int>::nodesCount() in main.o
This is in Xcode. It doesn't seem to like calling the private function in the public one, but I'm not sure why since I'm doing that with several other functions.
//public function
template <typename T>
int BST<T>::nodesCount()

I have a slider control on a dialog box. I am playing a video file and slider moves according to the video elapsed. Suppose I have set the slider range to 100. Now till some point say 90, the slider moves to the point wherever I click the mouse. but at the last point in between some range say 90 - 100 (to the end of the slider), if I click the mouse button anywhere, slider jumps to the end.
I am using a TimeLine control where user can add more than 1 video (1, 2, 4, 8, 10 , 50 etc......), If I use only one video, slider moves as per the video progression.....Issue arises when I add more than 1 video and click on the start button, slider starts moving....Now when I drag the slider to any position or I click the mouse button anywhere on the slider control, slider thumb moves to that position and immediately jumps back to some other position. This is the Issue, I am facing.
share some sample code where slider is moving with the video showing the progress of the video.
I want to implement a functionality similar to VLC player. Wherever user clicks the mouse, slider moves to that point.
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

I have to write a program (on linux) which will count character, words and lines like wc linux command. I'm trying to write this for last 3 days... First part of app I did and it works fine - command line options to choose. Then I've got a function read_file which I have to use to read a file. One of the options is to get the file name from user and if user will not type any name then the standard file is ubuntu dict file /usr/share/dict/words, this is not working as well...
Counting characters and lines is working fine but because I don't know how to get text from read_file wrote code to read file interior this functions. Words counting is working partly - everything is fine until there are two or more spaces, tabs one after another then counts extra words. Finally I need child processes in words and lines counting functions. Parent process should waits for all childs to finish and should be pipes to submit character counts back to parent process. How to do all this things with processes...
Code:
#include <getopt.h>
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <errno.h>
/*size of character buffer to read in a file. */
#define BUFFSIZE 1000000

Modify your code by adding your own tests to see if your functions work right. Include at least 6 separate tests, of your choosing.
For example, test the compare function with the first parameter as a blank string -- then with the 2nd as a blank -- then both. Test compare with the first string shorter than the second -- then the other way around. Test your copy function with long strings.
I am struggling with how to use the compare function with a parameter as a blank string. I tried leaving the first parameter blank but doing ("",text) but I don't think that is the correct way of doing this.

View 2 Replies View RelatedHow would I generate nodes inside a function for example I have a head node
Node * head = new Node;
Now I want to generate nodes for as long as the for loop is running
void CreateList(Node * h) {
for(int i = 0; i < 5; i++) {
Node * n1 = new Node;
head -> next = n1;
} }
Something like this but it should keep adding nodes to the list and change the head each time so how would I do this...
If I were to exit a program, is it okay if I fail to properly destroy whatever structures were allocated?
For instance, if I do this with SDL, there might be obvious consequences like a dead window perhaps. But if I do this with a POD structure, is it okay?
Also, I realize RAII is supposed to fix parts of this but it's not perfect when environments are suddenly cut off with something like exit(1/0);

i am facing some problem with qsort() function it work well if the last element of array is larger then the 2nd last element. But in case if last element of array is smaller then the 2nd last it will sort the whole array and remains the last as it is. For example
Code:
int group_id_local[max_j]={2,1,4,5};// it work fine, output should be {1,2,4,5} but if i have this one
int group_id_local[max_j]={2,1,4,3};
// output should be {1,2,4,3}
/* COMPARE FUNCTION FOR USING QSORT()*/
int cmpfunc (const void* a, const void* b)
{
if (*(int *)a < *(int *)b) return -1;
if (*(int *)a > *(int *)b) return 1;
return 0;

why it will not sort the last element?

I'm working with a cross-platform library which defines a function to obtain function addresses from a shared object (i.e. a DLL on Windows). Here's my modified version of the function which works (albeit only on Windows of course):-
Code:
typedef void (*SuilVoidFunc)(void);
/** dlsym wrapper to return a function pointer */
static inline SuilVoidFunc
suil_dlfunc(void* handle, const char* symbol) {
return (SuilVoidFunc)GetProcAddress((HMODULE)handle, symbol);
}
Now, here's the original (cross-platform) version which is giving me a run time error on Windows:-
Code:
typedef void (*SuilVoidFunc)(void);
#define dlsym GetProcAddress
/** dlsym wrapper to return a function pointer */
static inline SuilVoidFunc
suil_dlfunc(void* handle, const char* symbol) {
typedef SuilVoidFunc (*VoidFuncGetter)(void*, const char*);
VoidFuncGetter dlfunc = (VoidFuncGetter)dlsym;
return dlfunc(handle, symbol);
}
That original version fails at the final return line. The error message says "The value of ESP was not properly saved across a function call".
I'm assuming there's a problem with the declaration of VoidFuncGetter (i.e. it'll assume that the caling convention for GetProcAddress() is cdecl when in fact, it's stdcall). What's the most elegant way to fix this and still keep cross-platform compatibility?
The program will ask for the user to enter a value for x, then compute the following polynomial: 3x^5 + 2x^4 - 5x^3 - x^2 + 7x - 6.However, when I double check it with my calculator I get a wrong answer for random values of x. To simplify my problem I'm using only integers.

This function should delete each element in the list which is the same as this one typed by user. There are no errors, but function doesn't work. It deletes something, but not this element which should.

I have created a shared object in Ubuntu (libMYLIB.so). I am now trying to compile a simple test program (testmylib.c) to see if the shared object is properly built. I am getting an error that the build cannot find the shared object. My build command is:

where /dir/mylib is where my source and libMYLIB.so reside.
What am I doing wrong?
