C++ :: Codeblocks Not Finding Libs - Permission Denied

Oct 18, 2013

I upgraded to code::blocks and now I have the errors while trying to install sfml and sdl (to use in a dual project): Codeblocks libs:Permission Denied

Codeblocks libs is a custom folder I created and copied libs from the lib folders to because I got the same errors in the actual folders and thought it might be because of their location. What should I do?

C/C++ :: File Renaming / Permission Denied

Oct 9, 2012

I am writing a C++ program that finds the Word Documents on your computer that have '+' or "%2B" in the name and replacing those '+' and "%2B" with ' '. I am writing this program for my school's University Writing Center, so I predict the only places they will have these files are the USB memory stick, Desktop, Documents, and Downloads. I encounter a problem, however, when I run this program and it renames the files in Downloads: Permission denied. I am using the windows.h to do this. How do I give the program permissions to that folder?

update:This program is going to be written in C++.

C++ :: Permission Denied Error - ID Returned 1 Exit Status

Jul 13, 2014

I'm new to C++ and keep getting an error. I get a permission denied and id returned 1 exit status, the code is fine and as far as i understand this would be because my OS doesn't allow modification of currently running files which would make sense as when i look in task manager it shows my program running even though it has finished. Ending process/process tree does nothing as does using any third party process terminator.

There is no loop in the program or anything even a simple hello world program yields the same result. Only way i can re-run my program is restarting my computer or saving the project under another name and re-compiling...

C++ :: MinGW And Export Link Libs?

Jan 5, 2012

I'm building an app using VC++. The app links to a DLL built using TDM-GCC (which uses MinGW I think). Obviously, the DLL comes with a link lib.

If the lib is linked to another MinGW app, the DLL functions get found by name. So if the DLL builder updates his DLL, the MinGW app carries on working.

However, if the same lib is linked to a VC++ app, the functions get found by ordinal value. But MinGW doesn't seem to have any means of guaranteeing that a later build of the DLL will use the same numbering scheme. So his new DLL will break the pre-existing VC++ app that used it.

In VC++ this problem could be solved by using a DEF file but that doesn't seem to work in MinGW. So my question is:- can a DLL built with MinGW be somehow instructed to export its functions only by name - or at least to export them so that any other compiler will import them by name and not by ordinal numbers?

C++ :: CopyFile Error 5 - Access Denied

Dec 26, 2013

I am trying to copy files, but the windows + compiler gods will not submit easily today. In my code below I get the sysdirectory + the file I want to copy with:

GetSystemDirectory(sysdirect, sizeof(sysdirect)); //Sets system directory IE. C:WindowsSystem32
GetModuleFileName(GetModuleHandle(NULL), cfilename, sizeof(cfilename));
_splitpath(cfilename, NULL, NULL, fileName, extension); //splits the path name up into different pieces
_snprintf(rfilename, sizeof(rfilename), "%s%s", fileName, extension); // writes formatted data to a string

Then
if (strstr(cfilename, sysdirect) == NULL) { //returns a pointer to the first occurence of str2 in str1
char tmpfilename[MAX_PATH]; sprintf(tmpfilename, "%s\%s", sysdirect, filename);
cout << tmpfilename << endl;

[Code] ....

my tmpfilename prints exactly where I want it to go and my debug prints out an error 5 which is an access denied error. I was looking at the system("copy") function, but I don't think I would be able to use my pathnames. From what it looks like I would have to hardcode in like "copy C:windowssystem32".

C++ :: Installing SDL Extensions To CodeBlocks

Aug 30, 2013

how to use SDL just today, installed the standard SDL library on the compiler. But when i got to the point where I needed to install the SDL image extension library I thought I had everything correct but when I tried running a program using it I got errors. The non-extension SDL apps work just fine but when I try using SDL_image functions in my code I get problems, although when I begin typing the function the name shows up and i do not get issues with the .h, I feel its a link issue because I get errors such as:

ld.exe||cannot find -lSDL_image|
ld.exe||cannot find -lSDL_image|
||=== Build finished: 2 errors, 0 warnings (0 minutes, 0 seconds) ===|

I'm confident I have my /includes installed correctly. Also I was unable to find the 1.2 version for the Img extension so i reluctantly went ahead with 2.0 if that is perhaps causing issues.

C++ :: Running Certain Code In Codeblocks Sets Off AVG?

Jul 3, 2012

I've recently started to learn C++ and I'm using codeblocks as my IDE, but I keep getting problems with AVG free edition picking up random pieces of code as Trojans ?! I've put an example of some code that sets it off below, and the error message I get. Is there anyway I can set AVG not to trigger with any codeblocks coding I've done? I guess I could tell AVG not to trigger for that folder, if that's even possible?

Code:

#include <iostream>
using namespace std;
class MyClass{

void coolSaying(){
cout << "BUST A MOVE!!" << endl;

C/C++ :: CodeBlocks Random Math Quiz Generator

Nov 26, 2014

The user will be allowed to pick:

-the number of problems they want to do
-the type of problem (addition, subtraction, multiplication, division)
-the range of numbers for the problems (like 0 to 9, -100 to 100, etc.) [random numbers in the range]

Your program will then display the given number of problems and get the answer from the user. It will tell the user it they are correct or not. If they are incorrect, it will print the correct answer.

After the given number of problems are displayed, the program will give the user the final number correct and percentage correct. The user will be asked if they want to go again. If so, you will reprompt the user for all the information and run again.

I came up with code thinking I was going in the right direction but it doesn't work correctly at all. We have to use functions. My main issue is how do i call variables from another function so all of the functions work together. I repeat I don't understand parameters and calling functions. here's the code:

#include <iostream>
#include <cstdlib>
#include <iomanip>
using namespace std;
int get_user_range(int &x, int &y);
int get_random_number ();

C :: Finding Next Day Using Structures

Jul 21, 2013

Ok, for my Sunday homework I have to find the next day of the year using structures. Now, I can get the structure to read the entered date (tested that with a simple scanf to printf entered data), but I need to get it to be able to tell that it is the end of the month and print out the next month when necessary. Here is what I got so far:

Code:
//Cameron Taylor
#include <stdio.h>
struct Date{
int month;
int day;
int year;

[Code] ....

As you can see, I am trying to use an array for the max day of each month (excluding Leap Year for now).

Where I use the entered month to = 'i'. Then I use 'i' as the position in the array to see if next.day is = to the max day of that position of the array.

I am having no compiler issues with GCC using -w or -Wall, but after entering the current day the program stops working and doesn't go beyond the input.

commiedic@localhost Project18$ gcc -o -Wall Exercise4.c
commiedic@localhost Project18$ gcc -o -w Exercise4.c
commiedic@localhost Project18$ gcc -w Exercise4.c
commiedic@localhost Project18$ make Exercise4
make: `Exercise4' is up to date.

C++ :: Finding A Value In 2D Array?

Jul 9, 2014

I want to search a 2D array to see if it contains a certain value x. I can come up with three different ways to do this. Provided I have:

const int Rows = 40;
const int Columns = 30;
int SampleData[Rows][Columns] = { ... }

Is there any real difference (in terms of performance etc.) between these, or are there an even better solution?

Solution 1:
for(unsigned row = 0; row < Rows; ++row) {
for(unsigned col = 0; col < Columns; ++col) {
if(SampleData[row][col] == x) {
// found
} } }

Solution 2:
int* data = &SampleData[0][0];
if(find(data, data + Rows * Columns, x) != data + Rows * Columns) {
// found
}

Solution 3:
int* data = &SampleData[0][0];
for(unsigned i = 0; i < Rows * Columns; ++i) {
if(*data++ == x) {
// found
} }

C++ :: Finding GCD Of N Numbers

Feb 14, 2014

I know how to write the GCD for one, two, three, four, and etc, numbers. But I cannot seem to find a way to write a code that does it for 'n' numbers.

That is, the user inputs a number 'n', which determines the size of a dynamic array. Then they are prompted to input the values for each of the elements in the array that will constitute the numbers the program is to find the GCD for.

This records the array:

for (int count = 0; count < n; count++) {
cout <<"Enter the numbers you wish to find the GCD for, for term" << count << ": ";
cin >> GCD_n[count];
}

Here is a code for finding GCD of three numbers:

cout << "This program finds the greatest common divisor of three numbers.
"
<< "Enter the first number:
";
cin >> a;

[Code] ....

How to proceed coding a program that finds the GCD of 'n' terms.

GCD_n[n] is the array that contains the numbers for which we need to determine the GCD for.

My main problem is with writing a code that tests the elements of the array containing the list of numbers in GCD_n[n], all at the same time, such that:

int n;
cout << "This program finds the greatest common divisor of n numbers.
"
<< "What is the total amount of numbers you want to find the GCD for?

C++ :: Finding The Address Of A Bitfield

Aug 14, 2013

So I obviously can't take the address of a bitfield, but is there a way to get the address of the field holding the bitfield? What I'm trying to do is find the address of the parent field of a bitfield in a class. For example

Code:
class Foo
{
public:
int a;
int b : 4;
int c : 28;
[Code] ....

My goal is to get the offset address of the int storing c in class Foo. But offsetof uses the address of c, so I get a compile error since c is a bitfield. What I wanted as output from the above would be "4", since an int is 4 bytes (on my system). So the int holding both b & c starts 4 bytes from the start of the Foo class. Is there any way to do this in c/c++?

C++ :: Finding Grid Of Mines?

Aug 8, 2014

Code: There is a rectangular grid of numbers. The grid has m rows and n columns. So it has m*n cells in total.The rows are numbered from 1 to m and the columns are numbered from 1 to n. The top most row has number 1, the row next to it has number 2 and so on. Similarly, the left most column has number 1, the column next to it has number 2 and so on. Each cell in the grid has a unique coordinate which is (x, y) where x is the row number and y is the column number of that particular cell.

Each cell in the grid has an integer in {0, 1, 2, 3, 4, 5, 6 ,7 ,8}. Number in cell (x,y) is number of mines in neighboring cells (cells have at least 1 common vertex with cell (x,y))

Your task is to find grid of mines, i.e display an m*n grid of numbers {0, 1} (cell (x, y) is 1 if there is a mine in cell (x, y)).

Input
First line of the input contains two space separated integers, m and n. Next m lines, each line has n numbers in {0, 1, 2, 3, 4, 5, 6 ,7 ,8}.

Output
A grid of numbers {0, 1}

C :: Array Finding Position Of A Value?

Dec 24, 2013

So for a project I'm working on, I'm using an array and generating it's values randomly but unique. Currently I'm working on a 3X3 array and the generated values are in the range from 1-9. So I wrote a function that will tell me the position of the cell whose value is 9. This is the function I wrote:

Code: void Llogaritje1(int t[3][3],int &i, int &j){
int y,l;
for(y=0;y<3;y++){
for(l=0;l<3;l++){
if(t[y][l]==9){
i=y;
j=l;
break;
}
}if(t[y][l]==9) break;
}
}

But it doesn't work on all cells. Seems like at cells t[1][0] and t[2][0] the values that i and j take are 0 0 since when I print them after excecuting the function that's what it returns. I really don't understand why.

C :: Finding The Minimum Value Of Array

Sep 9, 2013

I am trying to make my program read a bunch of numbers in an array to find its maximum and minimum. the program will ask the user to enter in as much number as possible until they enter a non number/letter. i got my program to find the maximum value but the program couldn't read the minimum value. it always says zero. also everytime i enter the number 0, the program will just finish its loop statement. If i typed in a negative number, it'll read the negative number as its minimum.

Code:
#include <stdio.h>
int main()
{
//-------variables------------------
double list[1000]; // can hold 1000 items
int i;
char letter;
int max = list[0];
int min = list[0];

C :: Finding Diagonals Of Array?

Apr 11, 2014

Most of this program is working correctly, however when I get to the part on lines 70 to 78 to try and use the function on lines 103 to 113 to find out each diagonals value and then print each one back. But when this runs it only returns the value for [0][0] for each run through the loop and I'm not really sure why. I know its probably something simple but I'm just missing it,

Code:
1 #include<stdio.h>
2 #include<stdlib.h>
3 #include<time.h>
4 #define MAX 100
5
6 void display_menu();
7 int check_option(int);

C :: Program Finding Max Of Graph

Oct 29, 2013

this is my first year programming, and in my class, each week we have to write a program. last week we wrote a program in c that made random value point and made a graph of the random points that continued on forever. this week, we have to use statistical functions to find the sum, mean, max, and min of the graph. below is the code i have so far.

Code:

#include <stdlib.h>
#include <strings.h>
#include <stdio.h>
#include <stdbool.h>
#include "SwinGame.h"

[code]....

so, as you can see from the code, the parts i need are finding/ coming up with a function to find the max min sum and mean of the functions.

C :: File I/O Finding Max And Min Numbers

My question is to write a complete program that will search a file of numbers(numbers.txt) for the smallest and largest numbers and then write the values to the screen using a single pass through the file. File only contains type int and holds at least one int. My questions are am I reading in the first number correctly? Where would I read in the second number to compare to the current max and min?

Code:

#include <stdio.h>
#include <stdlib.h>
int main(int argc, char * argv[])
{
FILE *fin;
fin = fopen("numbers.txt", "r");
//check to make sure file opened
if(fin == NULL)
}
