C :: Wrong Result In Integer Conversion To Little Endian

Feb 18, 2015

I am trying to convert uint32_t or unit16_t to chars in little endian. When I was reading the char s from binary file I used memcpy so I did not need to convert them, but now I try this:

Code:

static void write2Bytes(unsigned char ** pDestStr, uint16_t* item) {
(*pDestStr)[0] = ((uint16_t) item & 0x00ff);
(*pDestStr)[1] = ((uint16_t) item & 0xff00) >> 8;
*pDestStr+=2;


[code]...

In the last function I try either to cast to uint_32_t or unsigned char but in both case I got wrong values. The original binary string read from left: 0x36000003 (it is number corresponding to 48Mbytes).

And the result when casting to unsigned char is T000000 and T(>00 for uint_32. So what's wrong? I need to get some string with will be corresponding to 0x36000003. does this kind of convertion take a lot of compute performance when I one would use it offten (like when one would do convesions for bitmaps).

Visual C++ :: Prompt User To Enter Integer Value And Character Code To Indicate Conversion

Sep 14, 2013

I'm expected to write a c program for this question :

Using these header files
#include <stdio.h>
#include <conio.h>

Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.

C :: Take Integer Input For Temperature And Display Message For Different Ranges For Each Day Of Week

Apr 20, 2014

I'm writing the program below to take an integer input for temperature and display a cheesy message for different ranges for each day of the week.

I tried using two if statements, the first to determine if the input is valid, and the else display that it was invalid and to try again.

The second set of if (if else) statements would evaluate a number input and display the cheesy message based on the value, or if it was out of range, to make you re input that days temperature.

I understand that the else statement is linked to the closest if statement, unless brackets are added to prevent this. I thought my brackets were correct, but I keep getting [Error]'else' without previous if'. The red lines are the if and else statement I'd like to be linked, and tried to do so by enclosing the 2nd if statement in brackets.

The assignment doesn't require the error checking, but if I don't use some form of it I believe it will just loop. Again I have to use the last 4 lines due to instructors rules, and have to use scanf and not strings or arrays.

This program will ask the user what the temperature will be for each day of the week. The integer input from the keyboard will be tested in a series of IF tests and a message will be printed depending on the temperature.

Code] ....

#include <stdio.h>
#define MAX 100
#define MIN 0

int main() {
int day = 1;
int temp;

C++ :: Check Wrong Input Data

Jan 20, 2013

i'm making a for loop for a mini game which required the user to enter the input number.Let say if the user accidently entered a character instead of integer the whole program will go haywire so is there anyway to check for the error and prompt the user to input the data again?Here is the simple program...

for(row=0;row<4;row++)
{
printf("Enter Row%d:",row);
for(col=0;col<4;col++)
{
scanf("%d",&num[row][col]);

C++ :: Cin Input Validation Returns Wrong

Jul 11, 2014

I have this function that is supposed to take a float as a parameter and then call the getLine() method to accept the users input. The function basically just checks to see if what the user input was of the same data type, if it is it returns the input value, if not then it keeps looping through taking new input until its correct. The problem is no matter what number you put in the output always returns as 140734799803512.

float InputValidation(){
float num;
string strInput;
while (true){
getline(cin, strInput);

[Code] ....

You also need to include <string> and <sstream>.

C++ :: Correct Answer From File - Cin Getting Wrong User Input

May 31, 2014

So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;
int progfiles() {

[Code] ....

This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer

i
c
i
Press any key to continue . . .

The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output

"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"

C :: Flushing Input And Why Do Have To Hit Enter Key Twice

Mar 6, 2015

I wrote a program that reads user input string using fgets() function. After this, program will ask if the user wants to save the string to file or does the user want to change the string or quit without saving. If user wants to change the string this must be made possible by asking for the string again. After this, menu will be printed again printing the choices available.

I had to flush stdin before getting changing input! However, problem is "Why do I have to hit return key 2 times, when I choose 2 and input string again." (I use code block 13.12 with windows 8.1 laptop) */

Code:
#include <stdio.h>
#include <string.h>
#define MAX 50

C++ :: Need To Enter More Than One Char Input Not Working

Jan 23, 2015

Basically I'm having trouble reading more than one character.I want the user to input character traits(ie, w, a), if two traits are entered they get the job.

But I cannot get my program to read more than one character input.

This is what I have so far...

C++ :: Input Does Not Enter Buffer When Sleeping

Aug 7, 2014

When the program is processing/sleeping, those char input at that time would not goes into the buffer until the next input request (such as calling istream::get). The program below shows this.

#include <iostream>
#include <streambuf>
#include <chrono>
#include <thread>
int main() {
std::cout << "Sleeping...

[Code] ....

I wonder if there is a way to distinguish between the input comes from the time that does not request it (i.e., during processing or sleeping) and those comes after the time does request it (in the example, after "Input something: ").

C :: Input Validation - User To Enter Six Doubles

Dec 20, 2014

I'm trying to validate my input. I require for the user to enter six doubles and if they don't then I want them to re-enter the information. Here is my code:

Code:
while (1>0) {
printf("Please enter arguments in the order: negative mass, positive mass, initial x-position, initial y-position, initial x-velocity, initial y-velocity:
");

if ( scanf("%lf %lf %lf %lf %lf %lf",&MassMinus,&MassPlus,&Pos[0][0],&Pos[0][1],&Vel[0][0],&Vel[0][1]) != 6) {
printf("Not all numbers were assigned!

[Code] .....

At the moment it just waits if you enter less than six numbers and if you enter any more than 6 it just ignores anything after the sixth number (so pretty much does nothing). Also if I entered 1 2 a b 3 4 instead of entering six numbers it would register that as 1 2 0 0 3 4 but I want it to make the user input the numbers again. I'm also aware that "while (1>0)" isn't good programming form but I'm not really sure what to use instead?

C++ :: No Input - Forcing User To Press Enter Twice

Aug 25, 2013

When the user gives no input, they have to press enter twice before "Done." is printed.

cout << "What do you want the name of your page to be? ";
std::getline(cin, pageTitle);
if (cin.get() == '
')
pageTitle = "Welcome to Website.";
cout << "Done.
";

Is there a way to print "Done." after pressing enter once?

Visual C++ :: Writing To Named Pipe Coming From A Service (session 0) Without Admin Rights

Dec 9, 2014

I'm trying to write to a named pipe created by a service, as we all know the session 0 isolation implemented in vista and forward makes this task a bit complicated.

well at this point i managed to make almost all to work but my real problem comes when i try to write on the named pipe from my GUI application with no administrator rights

If i run the GUI application with admin rights it works 100% but, I don't need that application to require the user admin rights and for security reasons i rather to leave it without admin...

so i started my research and i found that there is a way to achieve this by calling CreateNamedPipe() with a low integrity security attributes...

well how to implement but i finally made it, the problem is that it gets worse than passing null security attributes, it works with admin rights with NULL security attributes, but when i pass the low integrity security attributes it gives "access denied" even when using admin rights, so i guess im passing the wrong security attributes but how to manually create the security descriptor string.

This is the code:

Service (session0) SERVER

Code:
DWORD WINAPI PipeThreadRSVS(void* pParameter){
LPTSTR _PIPE_NAME = "\.pipeRSVHPipeIn";
bool Break=false;
char Received_Buffer[BlockSize+16];
DWORD BytesRead = 0;

C++ :: Check CPU / RAM USAGE / Temperature

Nov 1, 2014

I want to make an application that will check CPU/RAM USAGE and CPU TEMPERATURE and if it meets some requirements it will restart your system or do something else..but my problem is:

1) How do i get that info? (i know that in VB.net there is an easy way) but in C/C++ or Java?

2) Is it possible though a C program to execute a command and parse that info to your program?

I am mainly interested for windows but i need also info for linux too..
