C/C++ :: Find Max Number Entered By User And Terminate When Negative Number Entered

Jul 15, 2014

I am trying to find the max number entered by the user, and it should terminate when a negative number is entered. For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.

#include <iostream>
using namespace std;
int Max(int x);
int main() {
int x;

C :: Run Some Operation If A Key From Keyboard Is Pressed

Jun 2, 2013

I need to run some operation if a key from keyboard is pressed. so I go with

Code: c=getchar();

to get it read. yet the user could press a key anytime; so I'd need some if-loop. no plans on how it'd look like though...I suppose something like this below wouldn't work right?

Code:
if(getchar()==1){

C++ :: SDL - How To Get Keyboard Input Into Function

Aug 31, 2013

I am trying to get my keyboard input into a function, so that I can call a function like updatebuttons() and set global variables to 0 if the button is not down at the moment and 1 if it is. It seems simple, but I can't seem to get it to work right; I am not use to working outside of windows, so I am still a beginner with SDL.

C# :: How To Add Keyboard And Button Press To A Program

Apr 13, 2014

I have a problem where I need to add the ability to input numbers into a calculator program through either a form button press or keyboard press. I have the button press working fine though I can't seem to get the program to start with the cursor active in the textbox for keyboard input. I've use this.ActiveControl = result; "result" being the textbox. Though the issue here is the program starts off with the cursor active but only for the first instance of keyboard inputs.

Perhaps its the way I wrote the program but is there a way I can achieve this? I found a way to write this calc by having a single event for all button presses, opposed from an event for 1-9. Not sure if this is a good approach but here is some of the code.

private double num = 0;
private string calculate;
bool pressed = false;
private void button_Click(object sender, EventArgs e) {
if ((result.Text == "0")||(pressed == true)) {

C++ :: Enter By Keyboard Instead Of Command Line Arguments?

Mar 9, 2013

Actually the below program is for Dispersal Algorithm called Rabin-IDA; this algorithm divided the data into N pieces and then recombine it from M pieces (such that M<N).

Thus, the below program needs command line arguments,which entering by Project properties/Debugging. this argument is file name, where the program performing spitted the file into N files, and then recombine it from M divided files, and put it on another file which should also passing its name as argument .

Now my question is, How can i make this program enter the file name by keyboard??(i mean enter the files name by user from screen not as command line arguments)

The below code is just the main function of program, and the whole of it in this link (http://www.juancamilocorena.com/home/projects) Information Dispersal Algorithms Rabin-IDA

#include "include.h"
void __cdecl _tmain(int argc, TCHAR *argv[]) {

C++ :: Restore Keyboard Stdin After Reading From Pipe?

Apr 25, 2014

I use the following code segment to read and output the text piped to a program. If there is no piped text, the code segment is skipped and then the program continues. What I need to do is restore stdin to the keyboard after reading from the pipe. I use the PeekNamedPipe() and ReadFile() because reading from stdin blocks until it has something, and I don't want that to happen. After reading from the pipe, the program begins to execute, and the main loop can be paused and it prompts for a command. I just can't figure out how to restore input to the keyboard. Obviously the platform is Windows.

char char_buffer[1024];
DWORD bytes_read;
DWORD bytes_avail;
DWORD dw;
HANDLE stdin_handle;
bool is_pipe = false;

C++ :: Microsoft Code For Keyboard Input Interpretation?

Nov 22, 2013

at the moment my program is extracting keyboard data through accessing the virtual key states. However, it is not performing as I intended because the data I receive from the console does not concur with the actions the user performed.

E.G. When I type, it comes out like this.

what I get with my program: WWhhhheeen III typeeee, iiit ccoommes oout lllikkke thhhhiiis

TLDR: so basically Id like to know how other programs know how to interpret keyboard input, so that when I type I dont get multiple inputs of the same key press
