C/C++ :: How To Randomize Images In Multiple Picture Boxes
May 9, 2014Here's what i'm searching for: I have a form with 3 pictureBoxes (pictureBox1,2,3). The form also contains one button.
What I want is that when the user clicks the button (so button_click event) that the 3 pictureBoxes each show a different picture. And when I click the button again again 3 different pictures will load.
I already found out that I need to make an arraylist for the pictures (there are about 100 pictures). A System.Random
to select random images. But I have absolutely no clue on how to write this code.
C :: Reaction Game - How To Create Randomize Algorithm Which Gets Exponentially Faster
Mar 29, 2014I am creating a reaction game using a series of lasers and LRDs and need to make a function which waits for a specific pin in portb to be triggered high before it can move onto waiting for the next pin to be triggered. The time lasped before the "game loses" needs to get exponentially faster as the game goes on.
I am using statements such as if(input(PIN_B0)==1 generate_tone(G_note[2], 1000); but unsure how to write in c "wait x amount of time, if trigger move onto next random pin or no trigger go to lose function.
C :: Function To Round A Number To Give Integer Number That Is Closer To Real Value
Oct 9, 2013I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)
I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.

C++ :: Random Number Generator - Count How Many Times Each Number Shows Up

C/C++ :: Printing Partitions Of A Number Using Constraint On Number Of Values?
Apr 15, 2014I'm taking a C++ computer science course right now, and one of the questions on my latest assignment is this:
"A partition of an integer n is a way of writing n as a sum of positive integers. For example, for n=7, a partition is 1+1+5. Write a program that finds all the partitions of an integer n using r integers. For example, all the partitions of n=7 using r=3 integers are 1+1+5, 1+2+4, 1+3+3, 2+2+3."
I've been struggling with this problem for a couple days now, and how to do it. I understand I need a recursive function to grab variables, and probably an array or vector to store them, but where to begin.
I've been reading documents on partition generating and the concept still eludes me, and any other questions on here or other programming sites using partitions don't seem to have a constraint on them.
C :: Asks To Input Number Nad If Outside Number Asks To Put In Number Within Bounds
Mar 23, 2013I have to write a program that will ask you to put in a number between 0 and 9 and multiply it by pi. If the number put in is between 0 and 9 then pi is multiplied but if it isnt between 0 or 9, it will say the number is not between 0 and 9 and asks you to put it in again and will repeat until a number between 0 and 9 is put in.
I have got the program working to the extent that it the number is between 0 and 9 it will multiply it by pi but if its not between 0 and 9 it will say the number is not between 0 and 9 and ask to put in a new number.
I can't work out how to get the program to repeat itself if the number entered isnt between 0 and 9.
I have enclosed the code below .....
C++ :: Random Number Generator Stuck On 1 Number?
Nov 21, 2013I am working with C++ in Visual Studio. It's my first semester doing anything like this ever. Still, I am embarrassed that I am having trouble with this simple "coin flipping" program. The user tells the program how many times to "flip the coin" & then the program tells the user the results of each flip. You'll see I am randomly generating a 1 or a 2 within the function coinFlip to represent heads or tails. However, the problem is that if the user wants more than one coin flip, the "random" number stays the same for all of them, resulting in all heads or all tails. I am thinking this is an issue with the for loop that I have within the function coinFlip.
Code:
#include <iostream>
#include <iomanip>
#include <cstdlib>
#include <ctime>

C :: Finding The Closest Number To Another Number
Apr 10, 2014Try not to make too much fun of me for my logic, but I'm having trouble with this. I am trying to make it so the program takes a 1 dimensional array and a 2 dimensional array, and checks to see what row in the 2 dimensional array is the closest to the 1D array.
To compute the value of the 1D array you take the first row first element in the 2D array, and the first element in the 1D array, subtract and the absolute value.
Example: | 4 - 3 | = 1;
1Darray = 1.
Full 1 Dimensional Array:
3 1 6 9
Full 2 Dimensional Array:
4 9 1 5
6 1 7 3
0 8 2 6
To compute the value of the first row in the 2D array,
| 4 - 3 | + | 9 - 1 | + | 1 - 6 | + | 5 - 9 | = 18.
| 6 - 3 | + | 1 - 1 | + | 7 - 6 | + | 3 - 9 | = 10.
| 0 - 3 | + | 8 - 1 | + | 2 - 6 | + | 6 - 9 | = 17.
Thus row 1 being the closest row to the 1 dimensional array.
The code I've written so far seems to be going down the right path. Have a look below...
Code:
int i,j,tempRow,tempTotal = 0,firEle,cloRow;
firEle = abs( x[0][0] - y[0] );
for( i = 0; i < size; i++ ) {
tempRow = 0;
for( j = 0; j < size; j++ ) {
tempRow += abs( x[i][j] - y[j] );
[Code] ....
The whole temp part is kind of confusing myself. What I'm thinking is that I can add all row values up using
Code: tempRow += abs( x[i][j] - y[j] ); , then I need to compare that value to see if it is close to the "firEle" which is value I need to get closest to.
