class-problem

Anonymous — Thu, 07 Mar 2002 05:51:31 GMT

hello,

I created a simple class "Test", with 2 member variables: an integer and
a double. When I want to get the information back from a class member,
the double value always turns out to be 0.
Does anyone know what I do wrong??
(when I do the same in a simple c++ program, it works fine...)

class Test
{
public:
Test() { iVal = 0; \
dVal = 0; }
Test(int newI, double newD) { iVal = newI; \
dVal = newD; }
~Test() {}
void setiVal (int newI) { iVal = newI; }
void setdVal (double newD) { dVal = newD; }
int getiVal () { return iVal; }
double getdVal () { return dVal; }
private:
int iVal;
double dVal;
};

void CreateAndReadTest()
{
Test NewTest(5, 5.8);

acutPrintf("\n *** New Test Parameters ***");
acutPrintf("\n - integer value: %i", ActiveTest.getiVal());
// gives the correct info

acutPrintf("\n - double value: %d", ActiveTest.getdVal());
// always gives zero...

return;
}

Jeroen,

acutPrintf("\n - double value: %2.4f", ActiveTest.getdVal());
or a whole range of format options the .4 is the number of decimal places.

You should also initialise dVal = 0.0;

Thanks a lot!
Where can I find these format options??

Jeroen,

In any C++ book or in the C++ help!

You can format the string prior to output using this option!
e.g.
sprintf("\n%-35s %s %10.2f", temp, comma, total);

Note the "-" for justification!

Have fun!

Thanks again. 🙂
in a program that's not arx I always use "cout", and so did my c++ course,
that's why I'm not familiar to these notations...

greetz,

Even A C book will provide the info.
