pls help me with the separation of commas from the set of numbers ...its hard
|
|
|
|

i guess... pls help me separate the commas from the numbers so i can calculate the average... it hard to separate it when im just a bigginer.. pls
|
|

Thanks. your codes are c++ i think?

It's not their fault. Actually, the people here are such experts that they can write a turbo c compiler in less time than what it would take for them to figure out if cout/cin or std::string is a C-language feature or not. They have risen much higher than the realms of specific programming languages. They only understand the language of bits and bytes and in their mind, both string and char are just a piece of f*  memory holding some bits.

And what's your trouble about?

I know what you want. Just tell me if I am correct.
int main(void)
{
int a,b,c;
scanf("%d,%d,%d",&a, &b, &c);
printf("\nYou just entered: %d, %d, %d", a, b, c);
}
Pay special attention to the commas used inside the scanf function. I think it addresses your doubt to some extent. I had this doubt all my life.
Second, I suppose you will say that above program is very rigid as it allows input of only 3 variables. What if the no. of variables is not known.
Very valid question, I say. Only I have forgotten how to work with console and it give me creeps to find out about gets etc. See this [^]
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
int main(void)
{
char input[255];
int sum = 0;
int num = 0;
gets(input);
char* token;
token = strtok(input, ",");
while (token != NULL)
{
sum += atoi(token);
++ num;
token = strtok(NULL, ",");
}
printf("\nSum = %d, average = %f\n", sum, (num==0? 0 : (float)sum/num));
return 0;
}
Hope it helps?

THANK YOU SO MUCH.. it really helpes...cool...

(num==0? 0 : (float)sum/num)
what does this code do?..... is there any other alternative in finding the average i mean other formula..pls reply
|

Can you tell what is the conditional or ternary operator [? :] in C and how does it work? Any example that can help me in understanding it?
Answer my question and i will answer yours.

can anyone help me on this code. im trying to input a hindu arabic number in a text file input.txt then it will output a conversion of that number into roman numeral... but the problem is it wont output the convertion.. the out put are trash characters.... but this worked when i was not inputting in a notepad .it worked when i was inputting in the running turbo c... here are my codes...... the first one is when the inputs are still in c and the other is in a .txt file....

You can use Word Automation to open the .doc file and save it as a .html file. After importing Word's type library, it's about 5 lines of code.

Hi all,
I am new in MFC. 
I am struggling with one of my system's modules which is I need to edit filed's value in the data source depending on some variables.
My problem is I stuck with Recordset type because I making the editting via SQL statment and the following which are I done so far:
CDatabase DBDecaying;
CString SqlRulesDecaying;
CString sDriver("MICROSOFT ACCESS DRIVER (*.mdb)");
CString sDsn;
CString ssDSN("ODBC;DRIVER={%s};DSN='';DBQ=%s");
CString sFile("c:\\DB\\db.mdb");
sDsn.Format(ssDSN, sDriver, sFile);
DBDecaying.Open(NULL,false,false,sDsn);
CRecordset RecSetRulesDecaying( &DBDecaying );
int X=2,Y=3;
double NewActiLevel = 0;
SqlRulesDecaying.Format(_T("update Rules set RActiLevel=%f where CNum=%d and
RNum=%d"),NewActiLevel,X,Y);
RecSetRulesDecaying.Open(CRecordset::forwardOnly,SqlRulesDecaying,CRecordset::??????);
Regarding the first parameter I tried snapshot,dynaset and dynamic instead of forwardonly. nothing happens.
So what I should put insted of ???? I tried (Update,Can Update,..) but I had syntax errors.
So please any help will be appreciated.
Best regards.

Since CRecordset::forwardOnly is a read-only recordset, that would be the one to not choose. Any of the others should work.
moh.hijjawi wrote: So what I should put insted of ????
CRecordset::none should be sufficient.

First of all thank you.
I did like you mentioned but i have an error which is "Attempt to open a table failed- there is no columns to retrieve were specified" and I sure that the sql it is OK;
please any help

Have you tried:
CString sDriver("MICROSOFT ACCESS DRIVER (*.mdb)");
CString ssDSN("ODBC;DRIVER={%s};DSN='';DBQ=%s");
CString sFile("c:\\DB\\db.mdb");
CString sDsn;
sDsn.Format(ssDSN, sDriver, sFile);
int X=2,Y=3;
double NewActiLevel = 0;
CString SqlRulesDecaying;
SqlRulesDecaying.Format(_T("update Rules set RActiLevel=%f where CNum=%d and RNum=%d"),NewActiLevel,X,Y);
CDatabase DBDecaying;
DBDecaying.Open(NULL,false,false,sDsn);
DBDecaying.ExecuteSQL(SqlRulesDecaying);

Now it works fine. so there is no need for recordset statement.
Thank you very much indeed

Hi all,
I have a Report style list control an i want to search an item inside that list control using Find function.
My problem is i want to search that item in second column.
LVFINDINFO info;
int nIndex = 0;
info.flags = LVFI_STRING;
info.psz = FirstRun;
while ((nIndex = g_index->FindItem(&info)) != -1)
{
g_index->DeleteItem(nIndex);
}
This code searches value in first column only.
How can i do this...
To accomplish great things, we must not only act, but also dream;
not only plan, but also believe.

|

How about:
for (int x = 0; x < g_index.ItemCount(); x++)
{
CString strText = g_index.GetItemText(x, col);
if (strText == FirstRun)
{
g_index->DeleteItem(x);
break;
}
}

The following code genarates C4389 warning.
How to remove this?

int a = 9;
unsigned int b = 10;
if (a == b) // C4389
return 0;
else
return 0;
};
