C/C++ :: Rainfall Project Cannot Output Information Into Table
Apr 8, 2015
Have everything working fine as far as input and functions.. I am supposed to output the information as a table. I started to write a void function in order to complete this task. I know how to output the information if i were to have an array for the months, but how to display the months when I am using a switch statement.
#include <iostream>
#include <cstring>
#include <iomanip>
/* author: John Pierce
Description: program reads in averages, then prompts user for current month. The program then
continues to prompt the user for the rain fall amounts for the previous year. */
using namespace std;
void printMonth(int month);
[code].....

this last few days I've been coding this one particular file
Hero.cpp
namespace Hero {
namespace {
// all data here
}
}
then the code grew a bit to about 700 line
Then now I want to implement hero skill system It needs the access to data inside the unnamed namespace where I put just about everything.. but it's unnamed namespace, it's only valid within one file and I should hide all that data from Hero interface in Hero.h How should I do this ?

If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.

Write a C++ program to output information for three students. The information stored in your program contains student’s first name, middle name, last name, and test score. The following shows the information for the three students, where test score is in the int type.
John Jacob Smith 78
Mary Jane Weems 82

Your program should declare three named string constants for the three students. Each constant contains the student’s first name, middle name, and last name. You may use three int variables to hold values for the three test scores. The first name, middle name, and last name of a student are then extracted using the substr() function shown in class. Your program should also compute the average (in floating-point number format) for the three test scores. The average score computed should be printed to the screen with 2 digits displayed after the decimal point.
The following shows the output from the program. Note that all the output is left-justified with 15 character positions reserved for each.
first name middlename lastname testscore average

I am trying to retrieve information from a website [URL] .... and have written a C code as follows:
Code:
#include <stdlib.h>#include <stdio.h>
#include <string.h>
#include <curl/curl.h>
int main(int argc, char* argv[]) {
/* Exit status to return */
int exitStatus = 0;
[Code] .....
The output of this program should be:
From To
4504111 B0LPF3
4504111 P62993
The first print option [printf("%s", url)] gives the url output as [URL] .... which on being manually pasted in any web-browser gives the correct output but the program fails to give the output.

Whenever I run my program, It should be taking this string of information:
Shampoo 10 8.75 87.50
Pen 3 2.50 7.50
Headphones 5 20.99 104.95
MacAir 1 879.23 879.23
Raspberries 6 4.99 29.94
Oranges 5 2.79 13.95
Apples 3 3.85 11.55
From one file and outputting it to another, the finished product should look like:
Shampoo 10 8.75 87.50
Pen 3 2.50 7.50
Headphones 5 20.99 104.95
MacAir 1 879.23 879.23
cheapest item = Pen
most expensive item = MacAir
total cost = 1079.18
shopper = Mary Kay
Raspberries 6 4.99 29.94
Oranges 5 2.79 13.95
Apples 3 3.85 11.55
cheapest item = Oranges
most expensive item = Raspberries
total cost = 55.44
shopper = Winnie B. The Pooh
When I run my code however, it doesn't get past shampoo and will continue to add shampoo to the total cost infinitely. How can I change the code to produce the proper information?
CODE:
#include <iostream>
#include <fstream>
#include <iomanip>
#include <float.h>
#include <sstream>
#include <string>
using namespace std;
ifstream input_file;
ofstream output_file;
[Code] ....

I used to use OutputDebugString, and not using it now because it only allows to strings to be outputted, are there any methods that I can dump virtually anything to the console?
cout << thing << endl;
But what if I am not start running the program from the command prompt?

Project Golfer.cpp
So when you enter the number 99 its supposed to quit the program and it wasnt so i fixed that then i noticed that if you don't hit the green its supposed to loop back to a certain point but it was going to far back so i put a goto statement in and now it wont output my data table.

I have a large hash table, where each index has a container that has a doubly linked list. Things work up until releasing the memory. Each record is created with malloc, and each record->data is also created with malloc and the associated string is copied in using strcpy(). The table itself is released in another part of the program and doesn't produce and error.
/**
* valgrind --track-origins=yes
*/
==16898== Conditional jump or move depends on uninitialised value(s)

How to interpret valgrind. Error resolved on a small problem. Now running into issues on large (>10000 words to check) problems. It appears the virtual machine just can't keep up for some reason. Running the code on my local computer produces no errors, memory usage is minuscule, and profile tools don't report any issues.

So I'm supposed to write something that will output a multiplication table from two user input integers between 2 and 10.
For example it should display like this is the user inputs 4 and 5
1 2 3 4 5
2 4 6 8 10
3 6 9 12 15
4 8 12 16 20
I was hinted to used two for loops and this is what I have thus far, what I can't figure out is how to display it like the example.
#include <iostream>
using namespace std;
int main() {
int num1;
int num2;
cout << "Enter two numbers between 2 and 10." << endl;

So the latest challenge from jumping into c++ is as following.
Code:
Write a function that builds the multiplication table of arbitrary dimensions This chapter also talks a ton about 2d arrays.
So I've built my program thus far as this.
Code:
#include <iostream>
using namespace std;
int drawTable(int,int);
int main()
[Code] .....
So basically, the idea is that I can use the arrays dimensions as a placeholder, and just multiple them to get that specific spot, so table[0][0] = 0, [0][1] = 0 and so on. However the output actually seems to be randomly generated numbers so I'd like to ask, what am I doing wrong? Am I on the right track? Or have I missed the bus stop completely.

Write a program to create an output file containing a customized loan amortization table. Your program will prompt the user to enter the amount borrowed (the principal), the annual interest rate, and the number of payments (n). The payment must be rounded to the nearest cent. After the payment has been rounded to the nearest cent, the program will write to the output file n lines showing how the debt is paid off.
Code:
#include <stdio.h>
#include <math.h>
int main (void) {

I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)

I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?
#include "/home/onyuksel/courses/340/progs/13f/p9/util9.h"
#include "/home/onyuksel/courses/340/progs/13f/p9/hTable.h"
#ifndef H_TABLE1
#define H_TABLE1
void ptr_sort ( );

I have written an SQL statement that would:
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){
string query =
"SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id";
var cmd = new MySqlCommand(query, _connection);
var da = new MySqlDataAdapter(cmd);
var dtCounts = new DataTable();
da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?

I am a bit stumped with trying to write some code to get the tableadapter/binding source to "update" a current 'user' to the table.
I have the insert/delete methods working fine, but it's the updating that has got me screwed up.
Example of insert.
try
{
personTableAdapter.Insert(tFirstName.Text, tSurname.Text, Convert.ToDateTime(tDoB.Text), tPhone.Text, tAdd1.Text, tAdd2.Text, tSuburb.Text, tState.Text, tPostcode.Text, TeacherType.Text);
teacherTableAdapter.Insert(Convert.ToInt32(tTID1.Text), tRegNo.Text, tPassword.Text);
[Code]....
I also tried to do the updated string/original string with the tableadapter.update, but that didn't work either.

I have to do a project for Programming and he said in quotes
"Programming exercise 10.6: the programming project is as described, except do not represent the points using structures.
Assume, as known, the ten (x,y)-values corresponding to x=0.0, 0.1, 0.3, 0.45 ..etc and use y-values from the
function xsin(x); as in (x,y)=(x, xsin(x)) = (0.3, 0.3sin(0.3)).
Use value n+1=10, so the LaGrange polynomial will be order = 9."
What does it mean to not represent the points using structures??
