for our school project, we have to make a program which involves three students and the prices each of them paid for the meals. The program has to calculate how much each of the students has to pay/receive to/from the others. Most of it, we got from our teacher. The error we are getting is that we have to 'take care of the input/output order'. So if you type in the names/numbers of the students in a different way, so for example if you type first number 1, then 0, then 2 and 0 and 1 have to pay money to number 2, number 0 has to be in front of 1. Our output is that number 1 is in front of number 0.
I am trying to build a c++ that reads user input and arrange letters in ascending order.
for example, if the user input: Hello my name is Moe! the output will be: !aeeehillmmmnoos (ascending order)
my problem is that when i input hello my name is moe the output will be ehllo (not completing other letters) also when i change class size to 50, it outputs unknown weird letters.
This is my code:
#define CLASS_SIZE 10 #include <stdio.h> #include <iostream> void bubbleSortAWriteToB(const char a[], char b[]); using namespace std; int main(void){ int i;
I'm stuck again on a homework problem. I enter 9 8 7 6 5 4 3 2 1 in to the program when it asks me to. I print out the array (just before the bubble sort routine) and I get the numbers in descending order just as expected. So going into bubble sort routine, the numbers are correct.
I should get 1 2 3 4 5 6 7 8 9 as output.
But I get 1 2 3 4 4 5 6 7 8
Code: #include <stdio.h> #include <stdlib.h> int main() { int max_size = 20; // max size of array of numbers int numbers[max_size]; // array for numbers
I tried to make this code to output an array in Ascending Order but the output is showing weird output like 001fgc123 multiple times instead of the array.
What is wrong with my code?
#include <iostream> using namespace std; void ascOrder(int Array[],int length) { int n=0,i,orderNum=0; while(n<length) { for(i=0;i<length;i++)
I will keep this simple as I have the code written for my testing software program, I just want to add a feature of randomly generating the answer choice output order, I do not want to randomly output the full questions, but instead the choices (answers to the question), for example =
As you can see I would like to output the answers, choices randomly as in answer choice 3 will appear at the top instead of 1. and so on, it doesn't matter if the numbers move with the txt as the numbers beside the questions are txt.
I'm new to program breadth first search and for my assignment we have to implement a breadth first search graph and output the order of the traversal. The problem is when I run my program I do not get any output from my traversal. All I get is "Breadth First Search Traversal starts at Vertex 2 and the order is: "
Here is my Queue class

Question: What is the efficiency and big O of the selection sort algorithm when the input happens to already be in nondecreasing order?
Answer: Not sure... since the input is in nondecreasing order, such that example 0, 1, 1, 2, 3, 4, 4, 5 then there will be no swap, Just comparisons of emelemts. So it is big O of n
I'm trying to arrange names alphabetically from a text file. Inside my textfile, it's like : "John", "Edward", "Peaches", "Anna"... etc.(It has thousand more names, all with quotations, separated by comma and I think it's not typed line by line... but using only one line). How can I read each name separately?
this code, it works if the text file contains names separated by lines and without commas and quotations. I do not know with the case I've stated above.
string numbers[1000]; string line; string number; string y; string x; int z = 1; ifstream myfile; myfile.open("names.txt");
[Code]...
This only shows the data inside text file. I'm new in c++.
Write a program that accepts three values (int) from the keyboard into three variables a, b and c. After loading the variables, your program will arrange the values into a, b, and c, so that a contains the larger, be the next and c the smallest.
You can use any other variables in addition to a, b c, as you see fit.
You will have to use some variation(s) of the if construct.
There are many ways to program this, but your challenge will be to achieve this without doing all possible comparisons. In fact, three comparisons woudl be enough, if you , for example, determine the largest number first, and keep track of its position in some way , so you can compare the other two.
I think I might use a code similar to the one below.
switch (expression) { case constant1: group of statements 1; break; case constant2:
i am making a program that reads a file from .txt and print them out using linked list. However, i need to sort them from the highest price to lowest price.

i know its long but im afraid that i might miss out some things.
A Bookseller makes special discount for multiple orders of a book as follows:
AMOUNT and DISCOUNT as follows.
5-9 5% 10-14 10% 15-19 15% 20+ 20%
Write a C main function to read the amount of order from the standard input and compute and print the total price of the given order after the discount. Assume that unit price of a book is 10.00$
My problem is that.When i start with this
Code: #include<stdio.h> #include <stdlib.h> int main(void) { int number; float TotalPrice; printf("enter a number:");

I get 0 if i enter a number between 0 and 4(0 and 4 included). I don't know where I am doing a mistake. I also want to know if i can handle this buy just if statements. or how can i do it by while and for loops ?
I would like to, when running cat, send in some data like "testing" to its stdin, and then catch the output of stdout, and put it into a character array variable.Currently the parent stalls till the child is done.I imagine the parent has to some how detect that the child executed 'cat', and then send in input to stdin?Then somehow detect that 'cat' is done executing, and read the output from stdout? I have looked around and found "dup2", but I don't understand how to send in and get data to the child from the parent, especially since the "file descriptors" is not pointing to any files in the first place..
So I have a project in which I am processing audio signals in real-time. I want to create a class to do this using the ASIO driver. I don't want to use a cross platform library nor do I want to use windows API as it is very slow.
I'm trying to write something that when a user is at the command line, the user can type and it displays of list of commands the user can use to run the application.
I have a project, a montly paycheck. So it checks the monthly paycheck of each employees. but my problem there is how to add a new employee when u are a user or in the output of program?
How to structure the input of one .dat file and outputting into another one. I have to loop through a file structured "doe, john, 1500", check for errors and then increase the mp by 50. You also have to do this through using a person class too. I think I need to use a while loop to go to eof and use getline to input correctly, but im not sure how to structure it.

I'm learning C++. Is there some way to make program function on input from a port like usb port and can I send bits through the port? For example A usb cable connected to a circuit. I press a button and an AND gate on the circuit gets activated by a bit from the usb port and a fan in the room turns on.
I'm trying to write a simple program that will prompt for a string typed in by keyboard and save it to a file. I've tried lots of variations and this is just the latest version.
//Prompt for a string input by keyboard and save it to a file
#include<iostream> #include<fstream> #include <string using namespace std;
I want to create a function that will accept input from the user and return the input, to be used for further calculation. I know how to accept and return with integers as parameters , but how do i do it with arrays?
Suppose there is an array of numbers arr[]. Now, i want a function that accepts the input from the user, and return the array for further manipulation.
For example, if the array is arr[5], then i should call a function and accept the values from the user. Then, i should return the imputed values and print the same. How can i do this.
