Can i initialize variables with value when we creatjng class??

Question

Example:
Class temp{
Private:
Int a[3] = {12,2,3};
};

Answer 1

In any of these cases, in case of doubt, you should do this:

Just try it.

Make a little code, testing if what you want to do works.

#include <iostream>
using namespace std;

class C{
int a[3] = {12,2,3};
public:
void f() {
cout << a[0] << a[1] << a[2] << endl;
}
};

int main() {
C x = C();
C y = C();
x.f();
y.f();
return 0;
}

Answer 2

I think you can but the 'i' of int must be small 😅

Answer 4

Do you mean values for each instance? Or static class variables? Or something else?

Can you explain with more detail, what exactly you want to do?

Answer 5

For each instances

Answer 6

If i create object of temp t then t has a[3] variable with values 12,2 and 3.
Is it right to do?

Answer 7

It can be done. That's part of what constructors are for. You can have default values for some fields.
