I have a .txt file which contains a large amount of ones and zeros (tile map for a game) and basically I just want to know how to change say just the 12th value in the file from a 1 to 0 .....
View 2 RepliesMy coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code:
#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;
void change(double cents, int a[]);
int main() {
double Dollars;
double cents;

I have installed VS 2010 and VS 2012. VS 2012 uses SqlServer CE 3.5 and VS 2012 uses SqlServer CE 4.0.The problem is that when a project uses a 3.5 file it tries to open it with 4.0 even if the app.config says to use the 3.5 provider. The version of the assembly is pulled right out of the GAC. I uninstalled 4.0 and the reference auto updated its version to 3.5.1. However after installing 4.0 again it changes to 4.0. The error I am getting is that 4.0 cannot open a 3.5 file....they changed the file format from 3.5 to 4.0 and they are not compatible.
View 2 Replies View RelatedFor particular assignment, I am asked to evaluate data from an inputfile, let it be named "infile.dat". Next, it is required to output to this same file, but with the name of this file altered to reflect the changes of data. For example, if I want to change the original file name to "changed_infile.dat.altered" by adding the "changed_" prefix and ".altered" suffix, how could this be done?
From my understanding, there are no functions in <fstream> that could change the file name. However, there is a rename function in <stdio>, but it's not exactly what I am looking for because I want to append a prefix and suffix to this existing inputfile name. Although I could apply a brute force method by simply doing rename("infile.dat", "changed_infile.dat.altered"), I want to have my program to work with various input files of different names.
im trying to make a tool that can change the version of the file (.exe)

View 3 Replies View RelatedI have an application which is used for calibration for electrical components. Here I want to set a rootpath for this application. I did some research and I found out that I can get the rootpath of the application (that is where the exe is stored) But what I am really looking for is once I start the application the root path should be what I assign. For instance currently the root path is "C:UsersPublicDocumentsABC.ToolsProjects" but I would like the root path to be "E:New ABC" Is this possible? I wrote some code where I call the exe of the application and it opens the file in a folder that I specify :
private void NewJournal_Click(object sender, EventArgs e)
{
string filePath = @"E:New ABCabc.vnalog"
if (!File.Exists(filePath))
{
return;
}
string SelectedFile = @"/select, " + filePath;
System.Diagnostics.Process.Start(@"E:New ABCabc.vnalog", SelectedFile);
}
Now this code open the .vnalog file in the application. And this works great..!!! How can I now change the path within the application?

I wrote a program to write text contents to file stream through fputs, the file stream address was changed in the middle of writing text content to the stream (11% text content have been put into the file stream), that cause the file stream pointer can be evaluated problem and raise exception on stream validation code in fputs library function, my question is what things could go wrong to make file stream pointer changed its address to something else or a NULL pointer if the file stream have not been flushed and closed.

In the old days, there was graphics.h, but that isn't included now, and I would prefer to use some modern extension. I'd like to write it on Win7, then move it to Linux on Raspberry Pi. It would be nice to avoid a full-scale graphics system like OpenGL.
I am working on a program that is supposed to do I/O file streaming. I dont know if I can properly explain how its supposed to work but I have found the error on my code, I just dont know WHY the error is happening? If you look in the while loop, count changes values like it should, but MOVE and TIP doesnt. Count starts at value 2. So move is 108. Then count becomes 4, but move stays at 108?
tring rec;
fstream myfile("File.txt", ios::in | ios::out);
myfile.seekg(myfile.tellg(), ios::beg);
myfile.seekp(51, ios::beg);
[Code]....
The lines of code im getting errors on is
int move = count * 54;
int tip = move + 51;
Move wont change its value? It stays 108, causing this infinite while loop. Where is the error in my code to cause move to not change values like count does?
I seem to be struggling with I/O File streaming :(

instead of displaying

View 5 Replies View RelatedOn one of my assignments I have to find the optimal change. For example, if I were to have 70 cents and had only quarters, dimes and pennies, the best way to receive change using less coins all together would be 2 quarters and 2 dimes (4 coins all together should be displayed).
All in all, I understand my assignment, however there is something I don't know how to do (or can't recall how to) and that is finding the the highest number in an array to use in a function and be able to compare it.
#include<iostream>
using namespace std;
//function in which amount = money, changeArray is the array where money is stored,
//and numCoins the amount of coin types there are available in the array
int optimalChange(int amount, int * changeArray, int numCoins) {
[Code] .....
What I'm stuck with, is that I don't remember how to get the highest number from the array that way I can compare it with the total amount when I'm building my function. Also, the function has to call itself recursively.
So this is the code I have so far, I didn't know it had to be a dynamic array so how would I Utilize dynamic array allocation to size the modal array
#include <iostream>
using namespace std;
int main() {
const int arraySize = 25;
const int patternSize = 10;
