C/C++ :: Find Closest Arrival And Departure Times?
Nov 13, 2014
I suspect it is a logical error but I can't pinpoint it. The assignment is to input a time of day in 24 hour format, pattern match with scanf, and print out the closest arrival and departure times for that time. The arrival and departure times are in minutes past midnight in a constant array. I am getting no bugs but the program is not giving correct values.
/* filename: hw25.c
* Purpose: Finds the closest arrival and departure times
*/
#include <stdio.h>
#include <stdlib.h>
#define N 8
#define HOUR 60
void find_closest_flight(int desired_time, int *departure_time, int *arrival_time);
Write a function which takes string of integer numbers and length of a string. Function need to return value of element which is close to mean of all numbers and transform string without that element. If are more numbers in same "distance" of mean, function need to find first and throw that number-element.
In function without [].. with pointers.
I wrote this code below, programm find mean of elements and if mean is equal to any element of string.. the programm return that number. Idk how to delete that number and how to find closest.. for ex:
String=[4,7,10,3] sum=24 mean=6
The progoramm need to delete 7 and new string look like String=[4,10,3]
insert Code: #include <stdio.h> int main() { int n,i; printf("Elements of string ?
Consider a coordinate system for the Milky Way, in which the Earth is at (0; 0; 0). Model stars as points, and assume distances are in light years. The Milky Way consists of approximately 1012 stars, and their coordinates are stored in a file in comma-separated values (CSV) format one line per star and four fields per line, the first corresponding to an ID, and then three floating point numbers corresponding to the star location. How would you compute the k stars which are closest to the Earth? You have only a few megabytes of RAM.
int compareints (const void * a, const void * b) { return ( *(int*)a - *(int*)b );
[Code] ....
So whenever i hit something that is not in the array i would like to know the closes upper value. So for 4 closest upper value is 5, then for 8 it is 12 , for 35 it is 44. how would one do this?
This 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]; int ganttP[50],ganttStartTime[50]; printf("Enter no of Processes : "); scanf("%d",&n); remain=n;
Any good algorithm for calculating the closest points/distance between two line segments? I use some pretty general code: [URL] ....
which seems widely used and advertized on the web and works in most cases but seems to often fail horribly when line segments are nearly parallel. I've been messing with the SMALL_NUM value for division overflow to no avail. The calculated distance can still vary widely when nearly parallel.
I managed to isolate a specific incident where this happens in my code. The distance between segments P1P2 and Q1Q2 changed abruptly in one timestep from 1.05 mm to 0.90 mm (yarn radius = 1 mm), causing abrupt compression spikes. In reality the distance in the original timestep is definitely also around 0.90 mm but is not calculated as such. I find that the values of s and t (s=0 for P1, 1 for P2, t=0 for Q1, 1 for Q2) for the closest points are originally 0 and 0 (as well as in the previous time steps) and then change abruptly to 0 and around 0.29 in the new time step. What it should be, I still need to check out.

// Here is my code for displaying the data from the text file into a 2d array and height next to it, but I am not able to diaplay the height from 60 to 76 next to the row of the 2d array, as shown in the table below. This is my program:
Recently the health authorities have listed a new way to calculate the body mass index (BMI) of an individual. Values of 20 – 24 are classified as normal, 25-29 as overweight, and 30-34 as heavy.
The table below is a portion of a typical BMI table.
Since the calculation I performed gives me -71.77 Volts, I need to match this value to the time that this occurs closest to using my program, and output the time that this occurs at.
Here is my program so far: int main() { std::ifstream inFile; inFile.open("AP.txt"); ofstream results_file ("maxvaluewithinput.txt"); float TimeAtdVMax = 0; float VoltsAtdVmax = 0;

If you're curious, this program isn't for homework. It's part of the independent learning on C++ I'm doing for a Master's Thesis; the program will eventually model the APD90 of a ventricular action potential.
Try 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.
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.
I have been trying to make a program that asks for username and password, and if it is wrong it will loop back to the top. But i only want it to loop a set number of times, how can i do this? This is my code so far
I was wondering that why in the below code, the copy constructor is called 2 times.
Code: class A { private: static int count; int age; public: A()
[code].....
I think that when f(a) is called, since I am passing this as value, no copy constructor should be called. The copy constructor should called when the return object "x" is assigned to:
so i have to read a text file with an unknown number of lines and allocate memory to for the number of items in the text file.currently i read the entire file(counting the number of lines). i allocate memory according to the number of lines read and then use fseek() with an offset of zero to allow for the second read .
I create a loop that would repeat itself many times a second? Trying to do extremely basic graphics with a grid and system("cls") every time I run a command, but it still looks very jumpy. I realize system calls are evil. Any way to get rid of this too.
I have a question about SDL and drawing sprites (SDL surfaces). My idea is that the user can create a wall of separate sprites by create one sprite each time in the current mouseX and mouseY position, when the user push down the e-key. The problem is that I have no idea how I could draw the same sprite multiple times without to delete the previous one.
in a header file and the header file is included in several C files.
Questions:
At run time,
Is there just one copy of the const variable my_fl_dark_gray or are there multiple copies for the multiple C files?If a function uses the const variable, does the initialization statement "my_fl_dark_gray=fl_color_cube(...);" run every time the function is called or does it just run once and then when the function is called it just uses the value stored in memory?
Write a C++ program that compares the execution time of the above summation using two different solutions: one that uses loops, and another that uses the closed form approach. Use large values of n for the comparisons, such as, 10^7, 10^8, 10^9, 10^10, 10^11,10^12, 10^13, and 10^14. Provide a comparison table for the execution time in both solutions.Do not worry about the value of the actual sum. Overflow will occur in the sum value rendering it invalid; however, this is not the primary concern of the program. Execution time is the primary concern.
Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...).
For every char of the given alphabet, count how many times in the string
1----- the char is preceded by its predecessor in the alphabet (consider that the predecessor of 'a' is '9') 2----- the char is followed by its successor in the alphabet (consider that the successor of '9' is 'a') 3----- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition) 4----- what is the longest substring of characters strictly rising (the following is greater (>) of the previous) 5----- what is the longest substring of successive characters (i.e.: fhkjshdfruytyzABCDEfglsj => 7) 6----- the frequencies of any char (if in the string the character 'g' occurs 12 times, its frequency is 12)
but when I print the output using something like this:
outfile << "Owner Name: " << name << endl; outfile << "Address: " << street << city << endl;
(let's pretend I included spaces between the address components, which I omitted to save space)
I get an output file of:
Owner Name: John Smith Address:
The output stops after the name variable, which I believe is stored correctly. I don't think anything is storing in the address pieces, this is the problem.
I think it's because I'm not using getline() properly in this case. Can you string together multiple getline()s like that?
If this was my design, I'd read in strings instead, but that is not possible in this case.
