Dynamic array in a struct?

[Good Dreams]

Is it possible?

[Good Dreams]

Is there any Real data type? I read it here.

Data Type Ranges
C/C++ recognizes the types shown in the table below.

Type Name Bytes Other Names Range of Values 
int * signed, 
signed int System dependent 
unsigned int * unsigned System dependent 
__int8 1 char, 
signed char –128 to 127 
__int16 2 short, 
short int, 
signed short int –32,768 to 32,767 
__int32 4 signed, 
signed int –2,147,483,648 to 2,147,483,647 
__int64 8 none –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 
char 1 signed char –128 to 127 
unsigned char 1 none 0 to 255 
short 2 short int, 
signed short int –32,768 to 32,767 
unsigned short 2 unsigned short int 0 to 65,535 
long 4 long int, 
signed long int –2,147,483,648 to 2,147,483,647 
unsigned long 4 unsigned long int 0 to 4,294,967,295 
enum * none Same as int 
float 4 none 3.4E +/- 38 (7 digits) 
double 8 none 1.7E +/- 308 (15 digits) 
long double 10 none 1.2E +/- 4932 (19 digits)

I didn't ask for a complete list of all data types. In this case a simple yes or no would be enough.

As for the first question...?

Real is a misnomer -- integers are real numbers as well Float is correct because the decimal point "floats" around the number depending on the exponent.

struct mystruct {
    int *piArray;
};

void somecode() {
    mystruct xx;
    x.piArray = new int[50];
    delete[] x.piArray;
}

You're right. The thing is that I was considering more irrational numbers which are real too. I should have mentioned it.

Finally I see a practic use of pointers! I'm following the cplusplus tutorial which talks about many things, but it's kinda difficult to me to see how can I use them. In time I'll see it perhaps.

One of those things is a class. I see it like a way of organizing our code better. Am I wrong? I was watching this interesting thread started by kedaman. He mentions the use of classes to solve the problem. In which way can it be good to use a class? (in general, not only in this particular case)

Found a good example that shows to me a good use of classes (just closing topic).
If anyone is interested:Polynomial Class

Later

Didn't someone post that quite a while ago?

Yep,

Hurray for search feature!
