Declaration means it exits but it has no meaning. But where
as definition means it has a meaning. Without decalration
there is no definition. Why means without existing how can
we use.
Some situations we do both in a single statement like,
int i = 10;
here i is declared and definie with the value 10;
But some languages give some value to the variable without
defining like
class DiffsDemo {
int i;
}
DiffsDemo demo = new DiffsDemo();
print: demo.i;
output: 0;
This will happen because some default values are assigned
to that types. Internally at run time they will define.
