you are a tax calculator in company, and you should calculate the tax based on staff’s salary as follows:
-the salary is less than 600, the tax is 0.
-the salary is greater than 600 and less than 800, the tax is 10% of the salary.
-the salary is greater than 800 and less than 1000, the tax is 13% of the salary.
-the salary is greater than 1000 and less than 1500, the tax is 18% of the salary.
-the salary is greater than 1500, tax is 20% of the salary.
Write a program in C++ to ask the user to enter the salary then calculate the tax using:
If-Only structure, If-Else structure, Switch-Case structure.

|
|
So do it! Write that program! It won't write itself ...
|
|
|
|
|
It looks like a good start to develop a working program!

Hi there!
I have started this Tax software program for you:
#include <iostream>
using namespace std;
int main()
{
cout<< "Tax software developed by https://iq.direct" << endl;
cout<< "Enter Salary:";
double s = 0, t = 0;
cin >> s;
cout<<"you entered: " << s << endl;
if (s < 600)
{
t = 0;
}
if (s >= 600 && s < 800 )
{
t = s * 0.1;
}
if (s >= 800 && s < 1000 )
{
t = s * 0.13;
}
cout<< "The tax will be :" << t;
return 0;
}

Hi
I have done this many times streamin text, this time however the text just doesn't appear I do a SW_SHOW on both the rich edit and the dialog
So I decided just to do a simple test copy "this is a test\r\n": info the pBuff *pcb = 16 for the next call I have *pcb = 0 to tell rich edit no more
The Dialog box and rich edit appear with no test however When I press any character on my keyboard e.g type D The text This is a text magically appears in front of D
Any ideas are appreciated

|

No idea until we will see your actual code.

i'LL POST THREE pieces 1) the oninitdialog of the parent Cdialog 2) the Steamin 3) resource file Tell me if you want to see more thanks you

What is storage_ptr? Its type and value?
|
|
|
|
|
you think thats the problem I should make it a CRicheditrl *
BTW I did Call AfxRichEditInit and I did observer that storage__ptr had a Hwnd after the DoDataExange
void* storage_ptr;
|

ForNow wrote: C++Copy Code
void* storage_ptr;
You mean you pass an uninitialized pointer into your STREAMIN method?
BTW, did you debug your code (and, particularly, this STREAMIN method)?
|
|
|
|

The Ponter I pass to the streamin is 1) the data ptr and 2) the length of it I did debug it and it passed the value back that I wanted in pBuff and *pcb
storage_ptr should be of type CrRicheditCtrl * instead of void * but it does a value and After the Call Cdialog::OnInitDialog it Called my DoDataExchage and had a valid HWND
In in fact if you look at that small test when I pass "this is a test\r\n" back to pBuff and *pcb = 16 that doesn't display
When I type any chanarcter in the rich edit for example a D this is a test follow it for example looks like this DThis is a test
thanks

I could not test your "code" because there is a lot of problems with:
undeclared identifier
undeclared identifier
cannot convert from 'DWORD (__cdecl *)(DWORD_PTR,LPBYTE,LONG,LONG *)' to 'EDITSTREAMCALLBACK'
...
and so on.
Could you post a code (sample project) that would reproduce your problem?
|
|
|
|
|
is there anywhere I could zip it if not the total project is 6 .cpp files with 6 headers and resource file
thanks you are really nice
|
|
|
|
|
Sorry! I don't know.
But if you won't find a way to do that then you could repost your question in Visual C++ Programming
Or just email it to me: <my surname=""> at <onlinehome.de>
|
|
|
|
|
Ill take the latter thanks but this mini project is a tcp/ip application that gets data into the RichEdit from a z z/os machine
let me see if I can somehow segregate it The rich edit portion that is causing the problems and then get a clean build and i'll send it over thanks you are very nice
|
|
|
|
|
You have to simplify your project code until it will reproduce the problem. Just make a very simple project with your RichEdit without any TCP/IP and other IPCs.
Test it. If you won't find the reason of the trouble while debugging this test project then post it to me or/and to the community.

commented out IDC_EDIT1 and the stream out worked

Does it mean that your text was under the IDC_EDIT1 control? Or what???
|
|
|
|
|
No just commented out that control maybe it overlaid IDC_EDIT
Thank you
|
|
|
|

ForNow wrote: maybe it overlaid IDC_EDIT
Yes, it is what I meant in my previous post. 
|
|
|
|
|
For the class parameter the documentation says a redefined name (not sure what that means) the reason I am asking I am using a control for which I have a specific WNDCLASS which I registered however the CDialog::Create fails with that control statement in the resource definition
Thanks
|
|
|
|
|
We need to see the code and a bit more detail. If the control is not known at build time then the resource compiler may well have a problem.
