How can I solve this problem?




:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

C# help !!

I am taking a C# class and I am totally lost on this week's assignment I haven't been able to get much hoping someone here can assist. Time is of the essence. Here is this weeks assignment:

One of your smaller customers needs your help writing a program. Your customer has an e-commerce Web site but wants to avoid being sued for allowing children to make purchases without the authorization of their parents. Using the 6 steps of problem solving, create a program to verify the age of a customer wishing to make an online purchase. The customer will enter his or her year of birth, and your program will calculate whether the customer is more than 18-years old. The program will then display a message to the customer that his or her purchase request is accepted or denied.

Your solution must include the following 5 parts in addition to the coded solution:

1.A problem analysis chart with each of the following sections:
◦Given information
◦Required results
◦Processing required to obtain the results
◦Solution alternatives
2.A flowchart showing the program processing flow
3.A chart showing input, output, and processing
4.An algorithm in pseudo code describing the steps the program will perform
5.A description in 4–6 paragraphs of how each of the 6 problem-solving steps was addressed

 

Equation solving in c++

Hello!

The business problem is calculating certain Task time's of workers. I have only their total time per day and the amount task's they did in that time those task are split into types (Its that 18 variable's I already mentioned). An example:
8x+4y+0z+...+5n=4300[seconds]
8x+0y+0z+....+0n=1000[seconds]

Yes some workers have only 1 task done and other don't but that's not a problem as I can zero-fill those spot's or easily ignore unsolvable equations.

I'm trying to solve 2000 equations (2000workers/day) with 15 variables (15 diffrent tasks) . I found an algorithm that solves an equation (Gauss elimination) so that part I have behind now I'm puzzled how to calculate all combination's of those equations. I need to match each equation with all solvable combination's of others. I want have a all the possible variable values as output then I can run some statistical program to find my sweet spot for the task time but that's another story.
Any nice c++ trick you could suggest ?
