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;
[Code]....
why it will not sort the last element?
Code:
struct lista* del(struct lista* p, char* path1) {
char model[MAX2];
int len;
char ch;
printf("Type model.
[Code] ..... t
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 am unable to get the string seaching function to work. it always says "Nothing found" I am stumped.
Code:
#include <stdio.h>
#include <string.h>
char tracks[][80] = {
"I left my Heart at Harvard Medical School",
"Newark, Newark, You suck balls",
"Dancing with a dork",
"From Here to maternity",
"The Girl from Iwo Jima",

this programm should in theory create a labyrinth but it doesnt and i really dont have the skill to pick up where i have been mistaken so gcc runs it but it crashes and it doesnt produce any remarkable results even when it runs....
for example this should you run it with these parameters .

appear something like this
10111
10101
10101
10001

or like this

10001
11101
10001

but it only crashes....it works with recursion and it makes a array (which is Ptr) a set of 1 and 0 which 0 is the path and 1 is the walls...

I'm writing a program where the user inputs a number of rows, and that many rows of @ symbols are printed, where the first row has the same number of columns as rows, and each next row decrements the number of columns by 1. It prints out a totally wrong output and whatever I try it won't print the right thing- currently when I input 4 it prints out 5 @ symbols on the first row, and then 3 on all the other rows.
Code:
#include <iostream>
using namespace std;
int main ( ) {
int rows;
cout << "How many rows? ";
cin >> rows;

return a + b;

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?
i need a function that will work for both dynamic and static implementations of a function to get the transverse of a matrix. so far, i have this
Code:
matrix transpose(matrix m)
{
int row, col;
row = m.com_dim;
col= m.row_dim;
}
[code]....
this works well with my static implementation, but when i try it in dynamic it gives me errors. the function has to be the same for both dynamic and static implementation
I am unable to implement the insert function properly, every time i run the program i just get the first value and name, I am not getting other Id's and name.

I'm working on a program which creates data and saves it into blocks (different files), then reloads and converts it all. the .ftl file saves properly, but for some unknown reason, it won't let me open it for input after.
Here's the significant code:
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
stringstream filename;
stringstream newfilename;
string Filename;
[Code] ....
setblock will typically = 3, but for testing purposes is set to 1. this really has me confused. the compiler i'm using is Dev-C++ 5.2.0.1 on xp. i have tried pausing the program after the output file is closed, confirming the file has been created in the proper directory before continuing but still fails the .is_open() check.
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] .....
I have this:
string input;
unsigned short choice;
...
istringstream valid(input);
...
if(!(valid >> choice))
{
//some error
}
Ok. My code is almost 1000 lines, and I have splited some functions in headers. But the same function doesn't work:
template <typename T> bool valid_input(const string& input, T var)
{
istringstream valid(input);
return (valid >> var);
}
You can check it here: [URL] The output is correct, but in my machine with C++11, MinGW 4.8 (64 bit in a 64bit-Windows8), the output is incorrect. Why?
If you want more specific info, the problem is that I use input, I think. I use std::getline(std::cin, some_string).
I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size)
{
int temp;
int smallest;
int current;
int move;
}
[code]....
put it wont print the numbers sorted when I use my print function, just the unsorted numbers.
If yes then how?

When I run the program, it compiles correctly but does not give any output. I'm not sure what else to do. I've tried changing up the code in nodeCount(), leafCount(), NodeCount(), and LeafCount(). I've tried adding a count variable to both nodeCount() and leafCount() but that didn't work. If I fiddle with the functions, I get a whole mess of errors. Currently, the code is stable but just won't output what I want it to.
I'm having trouble with getting a sine function to work. All variables are defined earlier in the same section. I have the code in a button (where I figured it would go) but I get the following error:

I've tried other functions as well (abs, sqrt, etc.) to no avail, as Math only seems to pop up with two options: Equals and ReferenceEquals.
We have to make a function integrate to work with the other functions given. I had it working before but I would only get all -4 as my answers but only the first one should be -4. what should more or less be put in my integrate function?

This is my quicksort function. I have tried a lot of things but I am trying to get it to work to sort all the details I have stored in an array by there age. This is how I have entered the data.

I have the following function I would like to convert to work with std:string. I don't understand QT strings at all.

bool ok = false;
((uint8_t*)pData)[ i ] = hexText.mid( 2*i, 2 ).toInt( &ok, 16 );

We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.

I'm trying to pass my structure to a function using switch method, so that It will ask for user's name and age then then from the switch method it will call a print function, but my coding is not working.
View 7 Replies View RelatedFinally got to functions. Made a simple one that adds two numbers:
Code: int add(int a, int b){
cout<<"a+b=";
return a+b;
}
It refuses to give an output unless I use cout.
If I just call the function like so: "add(12, 24);", shouldn't it print out a+b=36? It only prints out "a+b=", unless I use "cout<<" ahead of the call.
My simple question is why does it need cout ahead of the call? Shouldn't "return" do its job and print out the number?
