C :: Round Up To Or Round Off To The Nearest Cent?
Nov 19, 2013how I would easily round a double or a float to the nearest cent. It was easy enough to do it in visual basic or java, But i cannot figure out how to do it in C.

C :: Rounding To The Nearest Cent?
Feb 4, 2014I'm having trouble with rounding to the nearest cent in this program. It's the only thing that i need. The result i need is just off by one cent. I tried multiplying the interest amount by 100 and adding .5 then dividing all that by 100 but that just made it worse. Here's the code:
Code:
#include <stdio.h>
int main()
{
int count=0;

C :: Round Off Float To Integer
Mar 10, 2013I have a float values I'd like to round off to the nearest integer value.
That is to say, if the float value is 44.234533, the integer value should be 44. If the float value is 44.682101, the integer value should be 45.
How do I do this?
C :: How To Truncate And Round A Decimal
Jan 14, 2014To one decimal place?
Code:
#include <stdio.h>
int main() {
double num, trunc, round;
printf("
Enter a Decimal:
}
[code]...
That's my code currently, I've gotten it to round as I want, but I want it to truncate to one decimal place as well.If i enter 4.157, It should truncate to 4.1, and round to 4.2.
C/C++ :: FLTK - Creating Box With Round Corners
May 8, 2014The problem says: Draw a box with rounded corners. Define a class Box, consisting of four lines and four arcs. So I wrote the below code for that exercise:
#include <Simple_window.h>
Simple_window win(Point(100,100), 600,400, "semi-ellipse");
struct Box: Shape{
Box(Point p, int ww, int hh): w(ww), h(hh)
{ add(Point(p.x-ww,p.y-hh)); }
[Code] ....
When I ran it I faced this exception:
Unhandled exception at 0x757FE9D7 (ole32.dll) in test.exe: 0xC0000005: Access violation reading location 0x00000004.
I know this refers to declaring "Simple_window win(Point(100,100), 600,400, "semi-ellipse");" in global state. But I did that because I had to do it. The problem is that how to attach lines and also object (here b) to Simple_window win in either parts (main() function and also Box struct).
C++ :: Do While Loop Skips Over Input The Second Time Round

C++ :: Game Loop Design - Restart Round?
Sep 30, 2013I have a simple game loop.
while(true) {
//round initialization stuff
while(true) {
//capture input, make pieces move,
}
}
I am faced with the decision of what is the best way of restarting the game. The problem is, the condition for restarting a game is very, very deep inside the game's logic. So returning returning... is not an option, or at least, it ain't gonna be pretty.
So one of my considerations is to use a goto label, like so:
while(true) {
//round initialization stuff
while(true) {
//capture input, make pieces move,
} restart_round:
}
This seems to be the cleanest solution, since it allows me to fully reset the 'state' of the round, by first having all the destructors(pertaining to the round's objects) called, and then the constructors and other initialisation stuff.
Are there any subtleties that I am missing regarding this solution?

View 3 Replies View RelatedC/C++ :: Time Gaps In Round Robin Scheduling?
Mar 26, 2015I've recently completed a fully functional round robin algorithm for a class, however upon running a myriad of test cases I found where mine fails. I think it best to show with an example:
Process-Burst-Arrival
P1 1 0
P2 1 1
P3 1 4
P4 3 8
P5 5 20
Currently what happens is this, it runs perfectly from process 1 through process 3. However once it reaches process 4 it does the appropriate thing and adjusts my total processing time (q variable) to the arrival time of process 4. Great! But then, it rolls over to check the queue again and it's bringing in process 5, changing q to it's arrival time. Then it proceeds to swap them in and out due to them both now being in the queue and time quantums/slices running out.
My question is this: How/where do I put a lock on the while loop that runs the simulated scheduler (round robin in this instance) to not grab the next process when there's a time gap in between each process.
This specifically is the two lines that I can't seem to get working as they should:
if(arrival[i]>q)
q=arrival[i];
FULL CODE BELOW
#include <iostream>
using namespace std;
void RR(int n, int burst[], int arrival[], int throughput)

C/C++ :: Round Robin Execution With Gantt Chart - Arrival Time And Burst Time
Mar 10, 2015This is a round robin execution. with gantt chart. arrival time and burst time. I think there is an error in my formula to get the right answer,i cant resolve it but my program is running. What is the code or the right formula??
#include<stdio.h>
int main(){
int i,j=0,n,time,remain,flag=0,ts;
int sum_wait=0,sum_turnaround=0,at[10],bt[10],rt[10];

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++ :: Rounding To Nearest Half?
Mar 9, 2014How do I round to the nearest half integer?
Example;
0 to 0.2 = 0
0.3 to 0.5 = 0.5
0.6-0.9 = 1
What's the formula for C++?
I found a way to do it in math but I want to know what I'd have to put in C++. It's (x*2+.5)remove decimal numbers and divide by 2. What do I put in place of "remove decimal"?
For ex; x = 8.4 using (x*2+.5)remove decimal then divide by 2.
8.4 * 2 = 16.8
16.8 + .5 = 17.3
17.3 - decimal = 17
17/2 = 8.5
I want to do something like;
cout << " Half number: << (x*2+.5)remove decimal/2 << endl;
What would I have to put in place of "remove decimal"?

C++ :: Store Coordinates As X And Y In A Vector To Find Nearest Neighbor Of Given Points
Oct 13, 2014Lets say that i have the coordinates of a 2D space (x and y), I want to store the coordinates as x and y in a vector to find the nearest neighbor of given points like i have:
#3.57 3.18#
#84.91 27.69
#93.40 4.62
#67.87 9.71
#75.77 82.35
#74.31 69.48
#39.22 31.71
#65.55 95.02
#17.12 3.44
#70.60 43.87
Each coordinates is like x y and it shows points 1 to 10 (like 3.57 3.18 is point 1 in 2D space ). My question is that how i add all x and y coordinates in vector? I started like this;
`struct point{
int x;
int y;
