In classes and objects when we use const keyword for a data member , we use constructor! I know that
question is why only constructor ? why const is intialized only with help of constructor? is there any other way if no, why not?

It helps if you understand what const is and means.
const = constant.

-Think of something or someone that does not change as constant-
A constant value has to be initialised with a value at the time of its creation because its value is constant and does not change.
To answer your question though:
You could set a const data members value with a hard coded value instead of setting it at initialisation, but that reduces flexibility.
Here is an example
