C/C++ :: Program That Assigns Passenger Seats In Airplane?
Apr 26, 2014
I am supposed to create a program that assigns passenger seats in an airplane. First I am suppose to generate an array with random X's. Then I am supposed to ask the user to pick a seat. From there I am supposed to check if the seat is already taken. My problem is when I ask them to pick a seat it generates an array of nothing but X's. Also how would I allow the program to accept the seat numbers as either uppercase or lowercase letters. for example if they want seat '3C' how would I allow them to enter the C as either a lower case or upper case.

The assignment is to read in a text file of passenger names (first and last initial), seats (A1, B1, C1, D1, A2, etc.), and ticket prices. The output is specified to be a table of passengers and their seats sorted by seat order, and I also have to print the minimum and maximum ticket prices along with the owner of each ticket, along with the average of all ticket prices. My arrays are all reading in correctly, and the minimum, maximum, and average ticket prices were all easy to find. My problem is the sorting.
We were introduced to arrays a couple weeks ago and this is our first time doing any sorting. We are supposed to use a bubble sort, and while I think I gather how to use a bubble sort, it's not working in my program (so obviously I don't really know how to use it). I have tried several different things, and sometimes a few seats/names will switch around (never the way I want them to) and sometimes nothing will happen at all.
New to programming, not trying to get homework done for me, need to bubble sort airplane passengers and seats by seat order (A1, B1, C1, D1, A2, etc).
My input looks like this:
A Z A1 555.55
repeat with different initials, seats, and prices however many times the user sees fit.
I have a 1D character array for the columns(A - D), a 1D integer array for rows (1 to maximum integer), 1D float array for prices, and 2D array for name initals.
Here's the function to read in the arrays:
void read_Arrays(char seat_cols[], int seat_rows[], char name[][LAST], float price[]) {
int i, j;
for(i = 0; i < FIRST; i++) {
for(j = 0; j < LAST; j++) {
scanf(" %c", &name[i][j]);
} scanf(" %c %d %f ", &seat_cols[i], &seat_rows[i], &price[i]);
}
}
Here's the sort. The way we were shown to do it was with a 'for' loop nested within a 'do while':
{
do {
flag = 0;
for(i=0; i < ROWSIZE-1; i++) {
if(seat_rows[i] > seat_rows[i + 1]) {

I can't get my program to print only AVAILABLE SEATS; instead it prints Both Available and Taken.
//Program allows you to delete and add seats to the Airplane. Also to upload seat settings as a text file.
#include <iostream>
#include <fstream> //file stream for text file
#include <string>
using namespace std;

I'm trying to create a program to calculate the flight time and fuel burn of an airplane. However when I repeated the whole calculation, it did not show any data or result like the previous calculation. In addition, the "If" statement that I used to test the "fuelRemain" doesn't work properly. I can't figure out why.
Here are the outputs [URL]

A small airline has just purchased a computer for its new automated reservation system. you have been asked to program a new system. Develop a program to assign seats on each flight of the airline's only plane (capacity = 10 seats) your program should display the following alternatives
Please type 1 for "SMOKING"
Please type 2 for "Non-Smoking"
if the person types 1, your program should assign a seat in the smoking section (seats 1-5). If a person types 2, your program should assign a seats in the non-smoking section (seats 6-10). your program should then print a boarding pass indicating the person's seat number and whether it is in the smoking or non-smoking section of the plane.
Use a single-subscripted array to represent the seating chart of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seats is assigned, set the corresponding elements of the array to 1 to indicate that the seat is no longer available.
Your program should never assign a seat that has already been assigned. When the smoking section is full, your program should ask a person if it is acceptable to be placed in the non-smoking area section ( and vice versa ), If yes, make the appropriate a seat assignment. If no, print the message " Next flight leaves in 3 hours! ".

so my homework assignment is to make a program of which removes any notes in a program file.
for example, you run my program it will ask for a filename, when entered it opens the file, copies everything in it and removes any double forward slashes (//) and anything after that up to the new line character ( ) and anything between /* and */ including the /* and */.
i created the entire program and it removed the // and anything after that up to the new line character but will not remove anything after the first / when it finds a /*. This includes the */ at the end of the comment.
the section of code that removes the comments is
//this loop removes all notes
for(i=0;i<buf.st_size;i++) {
if((filecontent[i]=='/')&&(filecontent[i+1]=='/'))//removes notes using //
{
for(i=i;filecontent[i]!='
';i++)
filecontent[i]=' ';}
[Code]....
i know that the section that removes the multi line comments would not remove the final */ at the end if it did work, i was planning to fix that later once it removed the comment.

My program is ruuning perfectly only problem is that i must transform it to program uses class, class student . Am very beginer in using classes, so far i do very easy programs using classes.
so far i have this
#include "stdafx.h"
#include "student.h"
student::student(vector<STUDENT> studenti) {
vStudent=studenti;
[Code] ....
I try to make it but its too difficult for me. in that student.h and student .cpp is 50 errors..
Here is my code

I've been working on a small SDL program and decided I wanted to throw the program on to a disc so I could show some people what I'm working on. However, when I try to run the executable, the program crashes and under more details it says that the fault lies on SDL2_ttf.dll .
Why does this program work inside of VS2012e and not in windows?
What I did :
Set the program to release, hit f6, and then tried to run the executable from windows.
Additional information :
Compiler : Visual Studio 2012 express
O/S : Windows 7 64bit
SDL lib : 32 bit version

is there anyway to have a program where it ask for three numbers and you shows which which number is the largest and which is the smallest, e.g.
Enter 1st number: 30
Enter 2nd number: 10
Enter 3rd number: 30
Largest = 30
Smallest = 10

I am working on a program to compute the natural log of numbers using several different methods, but I am having a couple of issues. Firstly, when using Borchardt's Algorithm I almost always end up with nan as a result, even though I am pretty sure I got the formula correct. Also, in my lnDemo.c file It doesnt give me the correct answer and the second time around I get a segmentation fault.
Code:
//myLog.h-------------------------------------------------------
//These functions will compute or aproximate the natural log of a number
//This method will use a formula to compute it
int lnFormula(double x, int m,double *result);

I have an issue with a switch case in my program. I execute it and it does fine all the way up to where it says, "Answer (1, 2, or 3): ". When I enter 1, 2, or 3, it gives me' "Not an input choice!" from the default of the switch case.

Can we use more than one 'if' subroutine in one program. I am trying to implement this but if I run the two subroutines at the same time the lower subroutine directly shows "invalid grade". But if I run one at a time then they work perfectly fine.
Why is this happening? Does the compiler think that its the same "if" routine. If so how do I segregate it???
Code:
printf("Enter a score:");
scanf("%d",&gr);
if(gr>=80 && gr<=100)
printf("A Grade
");
if (gr>=60 && gr<80)
printf("B Grade

I expected this program to print out:
Code: Enter your desired monthly salary: $2000___
Gee! $2000.00 a month is $24000.00 a year. Instead, it printed out:
Code: Enter your desired monthly salary: $2000___
Gee! $2000.00 a month is $24000.00 a year. I don't understand how it got the extra nextline in the middle.
Here is the code:
Code:
#include <stdio.h>
int main(void) {
float salary;

I'm trying to successfully run a program that calculates your BMI but, although it runs, it is not giving the the correct math. Instead, it gives me the number i've submitted as my weight as an answer. I'm using Visual Studio 2008 and the formula: weight / (height/100)*2
Here is my code

"Allow the user to enter an integer, between 1 to 9 only. You may use the value ‘0’ to terminate the program. Then display the output as follows:
Sample Run 1
Enter an integer (1-9):4
