C++ :: Truth Table Generator - If User Enters String Of Boolean Algebra It Will Output Table
Jan 25, 2013If 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.
C++ :: Goto Statement - No Output Data Table
Feb 26, 2015Project 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.
C/C++ :: Hash Table - Interpreting Valgrind Output
Nov 22, 2014I 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.

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.
C/C++ :: Rainfall Project Cannot Output Information Into Table
Apr 8, 2015Have 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>

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. */

C++ :: Output Multiplication Table From Two User Input Integers Between 2 And 10?
Jan 14, 2015So 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;

C++ :: Function To Build Multiplication Table Of Arbitrary Dimensions - Unexpected Output
Nov 8, 2013So 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.
C :: Program To Create Output File Containing Customized Loan Amortization Table
Nov 18, 2013Write 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.

C++ :: Hash Table Program - Sorting Pointer Table After All Of Values Entered
Nov 19, 2013I 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?

C# :: Lookup Non-existent Rows In MySQL Table And Then Update Another Table
Dec 15, 2014I 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?

C# :: Use Table Adapter With Textboxes To Edit SQL Table?
Mar 8, 2015I 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.
C :: How To Add New Value To Hash Table
Apr 18, 2013I have a problem with this function that adds a new value to the hash table or updates its data if the value already exists:

C++ :: Decode A Table To An Array
Aug 13, 2014I have recently run into a problem at work in regards to organizing information for some variables in a table and sorting them based on priority values...
For example:
Case ID: 0 1 2 3 4
1 (2 3) (1 2) (5 1) **the first number in the () is the priority*
2 **the second number is the variable id**
3
So from up above (I made it shorter than mine), I have a table with 8 columns for the different cases and 30 rows for the different conditions possible. I am trying to figure out a way to create some type of function that will be able to run through the row and pick the case with the highest priority first (from 1-8), and output the case ID, the priority, and the second number within the brackets.
I thought about creating a decoder that will sort the values and give an array with the outputs, but I know there must be a smarter way to sort the data.

Feb 14, 2013I've finally been able to get my coding corrected after doing this for 5 hours and watching numerous tutorials on it... But I now need to create a table. how to create a table with dashed lines like -----------------, both vertical and horizontal.
Another issue I have is that I'm having trouble trying to get a prompt to ask the user how many programs, tests, and quizzes he/she completed with their total points. I got the basic programming done, but need a prompt asking "How many (quizzes, tests, or programs) have you completed?"
Finally, the do-while loop is driving me insane, where I have to set certain values. If it is greater than 2, then I insert formula 1, but if it is less than 2, then I insert formula 2. Whichever way it goes, the total points earned minus the two lowest scores are then calculated into an average.
Code:
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
int main()
[code]....
The whole basis of the program is to calculate the averages of programs, tests, and quizzes done during a semester at a school. The user is asked how many of each category he/she has completed (total points earned and total points possible). All of this is then calculated into a cumulative class average in a table along with points earned and points possible for each category (along with tests and quizzes combined into one average along with individual averages).
C++ :: Duplicates In Hash Table

The inserting part works just fine, but the checking for duplicates where I compare the two values is crashing my program.
