What is the difference between a static and const variable?

Question

Can someone explain the difference between a static and const variable?

Answer 1

Static Variables:

• Initialized only once.
• Static variables are for the class (not per object). i.e memory is allocated only once per class and every instance uses it. So if one object modifies its value then the modified value is visible to other objects as well. ( A simple thought.. To know the number of objects created for a class we can put a static variable and do ++ in constructor)
• Value persists between different function calls

Const Variables:

• Const variables are a promise that you are not going to change its value anywhere in the program. If you do it, it will complain.
