C :: Finding And Changing String With Another String
Mar 6, 2015I have a question about this function.
Code:
char a[4] = {"aaa"};
strstr(a, "bb");
When I do this after function copies bb to the array it puts '' ? I mean last for array would be 'b' 'b' 'a' '' or 'b' 'b' '' ''. I am trying to learn the basics of searching a string, finding and changing them with another string.
C :: Changing Value Of A String Through A Pointer
Jun 11, 2013Basically, I have a pointer to a C string:
Code: char **objectData and a C string:
Code: char temp[350]; I need to assign the CONTENTS of the temp to the CONTENTS to which objectData points.
Code: *objectData = temp; //this changes the pointer. When temp is deleted, objectData points to some rubbish
**objectData = *temp; //this doesn't seem to be doing anything - the string to which objectData points does not change.

C++ :: How To Convert String To Double Without Changing Actual Data
Jun 3, 2013I have to convert string to double. i'm using "atof" function to achieve same.
I have string as "0.0409434228722337" and i'm converting with "atof" But i'm getting double value as "0.040943422872233702". Why it adds 02 additionally at the end?
More example :
"0.0409434228722337" converts to "0.040943422872233702"
"0.067187778121134" converts to "0.067187778121133995"
Is there any other possibility to convert string to double without changing data ?
C++ :: Changing Array Of Characters To A String Array?
Apr 7, 2013I have an array titled: char TypeOfSong[arraySize] where the array size is 15. I am reading data from a file into this array and the characters can be either 'C', 'D', 'E', or 'R'. Each of these characters stands for a word (sting) and when I output the array, I need the strings to show up, not the characters. I have been reading online and in my book but I can only find information on turning one array with the same characters into a string. How would I go about changing this character array with different characters into a sting?
The characters stand for:
C = Country
D = Dance Party
E = Elevator
R = Rock
C :: Changing The Value Of Something From A Function
Oct 30, 2013I was talking to someone earlier about how to change the value of something from a function, and they said what was needed was to use a ** to change something, and was wondering if I could get a walk - through of what happens. I understand a single pointer well enough, but a pointer through a pointer is kind of confusing to me. Here is a simple example.
Code:
#include <stdio.h>
#include <stdlib.h>
#define SIZE 5
int add(int ** TOP, int * stack);
int *stack = NULL;
[Code] ....
Why is it that when the program prints the address of TOP in main, it is different than the address of TOP in the function? Is it because it is a different instance of TOP because it is in the function? When I put the number on *TOP, and come out of the function back to main, it then says the address of TOP is the number entered into *TOP, and am not sure why. And the **TOP ++ at the end I am thinking it increments malloc by 1, therefore bringing the pointer TOP up to point at the next element, or am I completely off base there?

C++ :: Changing Some Bit Of A Number
Jan 1, 2015I use miracle library to work with big numbers. I defined a number for example X with 192 bit. at first X= 0 ;I want to change for example 3 bit of it to 1 randomly.as a example:
assume that X has 10 bit :
X=0000000000
random numbers should be :
1000010001
1010100000
1100000100
C/C++ :: Changing Complexity From O(n) To O(1)
May 5, 2012For the following code :
s = 0 ;
for(i=m ; i<=(2*n-1) ; i+=m) {
if(i<=n+1)
{ s+=(i-1)/2 ; }
else
{ s+=(2*n-i+1)/2 ; }
}
I want to change the complexity of the code from O(n) to O(1) . So I wanted to eliminate the for loop . But as the sum "s" stores values like (i-1)/2 or (2*n-i+1)/2 so eliminating the loop involves tedious calculation of floor value of each (i-1)/2 or (2*n-i+1)/2 . It became very difficult for me to do so as I might have derived the wrong formula in sums of floors . Need Changing complexity from O(n) to O(1). Is there any other way to reduce the complexity ? If yes ... then how ?
C++ :: Changing From BigInteger To GMP?
May 15, 2012I have this code which previously used the BigInteger library, however now I have GMP installed and I want to use that instead.
I have read the manual but I cannot figure out how to use GMP in this function without getting errors.
Here is the function:
Code:
int lucas(long p){ //p is a number in the range of 2 up to 50,000,000, possibly bigger
int s = 4; //previously assigned as a big integer
int z; //used in the for loop below
int M = 2; //previously assigned as a big integer
for(z = 1; z < p; z++){ //this accomplishes the same as 2 to the power of p, and is stored in M
M *= 2;
}
M--;
[code]....
I can initialize variables using the gmp library, but when I'm trying to use the mpz_pow_ui() function I get errors because it wants me to use long integers, which are too small for the numbers I want to work with.
How can I re-write this function to use GMP?

C++ :: Changing Array Values

C++ :: Changing Variable In For Loop
Apr 28, 2013I have a problem with my code which I can't work out:
double Mi = 200*pow(10,30);
cout << "
Enter accreted mass increment in solar masses
";
cin >> dm;
cout << "
[Code] ....
Basically the loop works, but gives the wrong results.
I need, at the end of the loop, to sort of "redefine" Mi as "Mi + Macc". I then need it to repeat the loop, and at the end add another Macc so that Mi becomes "Mi + Macc + Macc", etc.

View 4 Replies View RelatedC# :: Changing Focus Using Program PID
Apr 17, 2014For the past couple days I've been making small improvements on a program I made to keep track of a battle count while playing a game. Mainly to reduce the chore of keeping track yourself while you're playing. But it still becomes a hassle to switch back and forth between the program and your game and I was hoping to be able to set focus to the game after the BattleCount method is called.
Currently I am importing a DLL that somebody recommended I use to make a ActiveProcess method that accepts a integer as a parameter which would set the PID but it doesn't seem to be working. The two methods are as follows.
private void countDownClick(object sender, RoutedEventArgs e) {
//Calls a method within my class that subtracts and adds battle values.
counter.CalculateBattles();
//These two change text on my WPF forms with accessor values from my class.
battlesWonText.Text = counter.BattlesWon.ToString();
battlesLeftText.Text = counter.BattlesLeft.ToString();
[Code] ....
This is the C++ code they told me to use to set focus to another application using a PID.
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
const UInt32 SWP_NOSIZE = 0x0001;
const UInt32 SWP_NOMOVE = 0x0002;
const UInt32 SWP_SHOWWINDOW = 0x0040;
[Code] ....
I'm simply trying to figure out how to set focus to a foreign program using their PID and a button click event in WPF. I'm using Visual Studio 2012 on Windows 7.
C# :: Changing Database Values?
Dec 14, 2014I'm working on a project where we access a tiny premade database in order to log into and access another page. I got the log in part working right, but the last part of the project asks me to lock out the account after a certain number of failed attempts. I'm not sure if I need a method to do this or if I can do it right there in the button handler. I tried creating a method to use on the object that was already there, but I'm not sure if that's the right way to go about it. It says it locks the account, but the value in the database never changes, and I don't know why.
//from the login button handler
protected void btnLogin_Click(object sender, EventArgs e) {
bool IsFound = false;
clsDataLayer dl = new clsDataLayer();
IsFound = dl.GetUser(Server.MapPath("~/AddressBook.mdb"), txtUserID.Text, txtPassword.Text);
if (IsFound) {
Response.Redirect("~/frmUpdateAddress.aspx");

Visual C++ :: Changing Code From TCP To UDP
Mar 20, 2013i had created a client server program in MFC using TCP but by doing this the server can only work on one computer because you have to tell the client the ip address to connect to i.e
Code:
ServerAddr.sin_addr.s_addr = inet_addr("10.13.31.112");
so i want to change my code so that i can use broadcasting but i found out that it only works using UDP. I tried changing the code but the error message "error with sendto: 10047" displays when i run the program.
that error means
Address family not supported by protocol family. An address incompatible with the requested protocol was used. All sockets are created with an associated address family (that is, AF_INET for Internet Protocols) and a generic protocol type (that is, SOCK_STREAM). This error is returned if an incorrect protocol is explicitly requested in the socket call, or if an address of the wrong family is used for a socket, for example, in sendto.
here is the code from server:
Code:
WSADATA wsaData;
WSAStartup(MAKEWORD(2,2), &wsaData);
int port = 7171;
if (param)
port = reinterpret_cast<short>(param);

C :: Changing Cents Into Individual Denominations
Sep 16, 2013I haven't actually learned how to use arrays yet but I know the basic principle of it and decided to try and implement one to improve my code. I'm sure the thing is a bug ridden mess but I would particularly like to point your attention to the function sortDenomination(). Is what I am trying to do in the loop possible?
The reason why I want to do it this way and not with if statements for each denomination is because I can then easily apply this to the second part of the assignment which sees us split a double into dollars and cents and then process each separately. All I would have to differ for each is change the money_loop variable to include the last two denominations in the array.
Code:
#include <stdio.h>
/*Reads cents input from the user.*/
void getCents(int &read_cents) {
printf("Please enter the amount of cents between 5-95:

C :: In Two Dimensional Array 0,0 Spot Keeps Changing
Jan 12, 2015I have a 10x10 array, initialized to all zeros. I create 2 random numbers for the purpose of guessing a position in the array.
However, when I print the array, the 0,0 spot keeps shifting to match the 2nd random number generated. Is there something strange about the 0,0 spot?
Here is my code:
Code:
seedrnd();
for (x=0;x<2;x++) {
randArray[x]=rnd(10);
}
for (x=0;x<2;x=x+1)
[Code] .....
The 2nd to last print statement actually prints randColumn. The last print statement correctly prints 0.
C :: GPIO Input With Changing States
Feb 4, 2014I have a GPIO pin(GP4) on a microcontroller with a continuous digital pulse train coming into it. I am writing to it in C and do not have interrupts on this chip. I have been calling my input "#define inputA GP4". In C, I would like to be able to find the positive edge of a pulse and trigger the timer on it. I'm not sure if an XOR will accomplish what I need by storing inputA to another variable at some point. Would it be possible to accomplish this by writing code that acts like a positive-edge triggered flip-flop?
The other problem that I have is I need to be able to do this and not get caught in an infinite loop where I can still do other things sequentially with my code, if for instance, inputA goes to 0 and stays at 0 permanently. This means that my option of using while(inputA=0); is out of the question.
C :: Changing Order Of Numbers In Array
Dec 10, 2014I want to write a programm that will reverse the order of the numbers in an array (e.g. as an input 1,2,3.5,4 and as an output i want 4,3.5,2,1) . But i have to problems:
1) I do not know how to properly change the type of a numbers inside an array from int to float or double, changing int to float in front of the a[10], does not change anything instead the code does not want to compile then.
2) I also want to make an array of a number of elements typed by a user with use of a "do" loop and how to put this parameter in the code.
Here is my code:
Code:
// ConsoleApplication3.cpp : Defines the entry point for the console application.//
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[]) {
int a[10], i, n;
int pom;
do {

C++ :: Changing Global Variable In A Thread
Jul 28, 2013I have a small problem with my program. It is kinda a mess but I will try to explain you what I am trying to do. I have some threads. One of it, it attempts to detect a game client. So my code is sort of like that:
DWORD ProcessID; // The process ID of the game client
void test() {
char* text;

So basically, its like the variable changes, but only inside the thread... why does that happen?
