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.

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 main()
{
int a = 9;
unsigned int b = 10;
if (a == b) // C4389
return 0;
else
return 0;
};
|
|
|
|
|
use
unsigned int a = 9;
unsigned int b = 10;
or
int a = 9;
int b = 10;
There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.
