The following 2 codes are almost identical, only that the switch statements are slightly different. The 2nd code has the issue of requiring an additional enter key to be pressed when I enter '3' as input to exit the program.
Working code :
Code:
#include <stdio.h>
#include <ctype.h>
#include <string.h>
void clearKeyboardBuffer() {
int ch;
while ((ch = getchar() != '
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?
I know how to check if a particular button has been pressed but I basically want to disable the delete button when ever the listbox has lost focus. I am having issues with the fact the button gets disabled before it receives the message. Is their a way around this that is non hacky?
How would I detect if any letter key is pressed. Would I have to use GetAsyncKeyState() for every letter key? Or could I have some kind of loop going through all the hexadecimal values for every letter? I don't know how I would go through hexadecimal values with a loop.
So I'm in the process of building my 2D game in Allegro5, I'm building a side platform game and at the moment I have a sprite being able to walk left right and jump. What I want to do is put a time delay on the jump function so that when a user presses the jump button and the sprite has carried out the jump function I want there to be a 1 or so second delay before the jump button actually carries out the jump function again.
I have quite a bit of code so not sure what bits to place in here, I'm more looking for a way of doing this, so providing me code isnt really needed just a way it can be done.
Things that might be useful to know:
At the moment I have a timer initialized in allegro which is used with my FPS int to mean that my game runs at 60FPS.
I have a bool bIsOnGround which maybe could be used into this, I'm not sure...
I have been learning C# so I've been dragging and dropping. I have a "First Name" and "Last Name" text field. I want to add this to a combo box called something like "User List", which will list the last named then the first names. However I figure I can work with something that can get me to store the names in the combo box.
So. I have two things I need to know:
What do I have to do to have when the button is pressed, add to the combo box?
Is there a way to retain all the entries I have entered? Or no?
So, I've been working on a project recently, and the only thing remaining to do is a detector to whenever down arrow key is pressed. The down arrow key can only trigger when a certain check box is checked and this will have to work with a timer either. The problem is that how to make the down arrow key press detector(I've got the check box and timer ready tho).
I would like to know how to press a key as if it had been pressed on the keyboard in a program. I would also like to know how to read input from a xbox 360 controller. I want to know how to do this so that I can add joystick support to a few mmos that I play that do not already have it.
I am currently using Flash. Here are two images I will be referring through without this post:
1: [URL] ....
2: [URL] ....
So basically, when I click the generate buttonon the first image it takes you to the second image. What I want is when I click the generate button it comes to this screen, aswell as choose a random word from each list that I will make (Who List, What List, When List, Where List, and Why List) and place the word next to its position. When you click New Idea I want it to also generate another set of random words from the lists. How can I do this?
cout<<"1. runtim"; cout<<"2.tims"; cout<<"Your selection will be automatically neglected within (function to be inserted for time ) ";/* insert timer here */ cout<<"What kind of process u need to do"; . . . .
I have 2 questions
1.the timer function has to be such that when any key is pressed in between the specified time its has to stop its counting and go to the nest line and functions . i checked sleep function but if any key is pressed its does not break out of the sleep program and execute the next command
2.and if the timer has completely finished running then it has to skip few lines and execute the program .
Nothing complicated, and it works well ... except one thing: when I press the shift key and the mouse is moving by SetCursorPos, is moving pretty slow ... why ? I can not figure out why ! For testing, I attached the test project ...
Code: /* generals is the first array. Max 10 elements. numGenerals is the element count of generals.
genBuff is the second array; it is to be checked/pruned. genCount is the element count of genBuff. genBuff will be a max of 171, but be pruned to no more than 10, and no more than the complement of the element count of generals. */
[Code] ....
(I do have comments in the actual source, different from above).
I have two int arrays. They hold values from 0 to 170. The first one will never be more than 10. The second will be at most 171, but will be whittled down to at most 10, usually less. 171 is worst case, most users of this particular program will probably be reasonable and not try to add all 171 (max is 10 anyway). The first array is the original array. The second array is a temporary array. Any value in the second array that is also found in the first array, is removed from the second array, since all values in the first one must be unique. After this pruning process, both arrays will collectively contain no more than 10 unique elements; the elements from the second will be added to the first.
So right now I have three nested loops. I figured with the miniscule array sizes it wouldn't be a big deal. I can think of a way to remove one or two of them, but I want to be sure that I'm still writing clean, legible, good-practice code. The first loop walks through the first array. For each element in the first array, there is a second loop to walk through the second array to check for duplicates. If a duplicate is found, the third loop walks through the second array to overwrite the duplicate while preserving the second loop's position (j).
Is this dumb? I know that the big O gets worse and worse the deeper you go with nested loops. Even though the arrays are really tiny, is this still a thing to avoid?
I know how to remove digits in number from right to left.For example: the number 319. If I do (number /= 10), I get 31.how can I remove digits in number from left to right.For example: the number 319. If I will do something, I will get the number 19.
class List; List *deletezeroendlist(List* L); class List { public: intdigit; List*nextDigit; public: List():digit(0), nextDigit(NULL){} List(int d, List *next):digit(d), nextDigit(next){}
I have tried many different ways but it is still not the answer / perform the function List *deletezeroendlist(List* L)
Below is my .h file and the code below that is my function that I'm having troubles with. Its suppose to take in a users topic and see if that topic exists, if it does exist then find the keyword, commentcompare will find where that keyword is and delete the comment. However its not deleting anything and its returning temp is NULL.
class comment //adds a comment { public: comment(char * create_comment);
How can I remove an element in a list when I have only an iterator that points to the object I want to remove. Is there a build in command? remove() takes an object reference as its argument. Is it possible to convert the iterator into a pointer type so it can be deferenced and passed to remove?
This is the code I am working on:
//player.cpp void Player::CheckCollectableCollisions(std::list<Collectable>& c) { std::list<Collectable>::iterator i = c.begin(); while(i != c.end()) { if (Collider::CheckCollision(pNodes_.front().getLocation(), i->getLocation()))
I am trying to remove the first digit so if the user enters 12345 it should output 2345 the code i have works only for removing the last digit how would i go about removing the first one?
#include <iostream> using namespace std; int removeFirst(int n); int main(){ int n, m; cout << "enter number" << endl;
Im supose to use <>bool removeTile(char, int, int, char[])<> to do this "function that takes in the choice (D or S) and the two dice numbers and the board as input arguments. When the move is legal and the tile is available for removal, it removes the tile according to the choice by marking the tile as ‘X’. Returns true if the move is successful."
