In const parameters,?

#1

we have written cout<<E.tyres ; and it is showing 4.
but we haven’t changed the parameters in the object that we created in the main .

what does const parameters mean .and how can we make setName as a const parameter ?

#2
  1. as tyres is constant variable and we initialize it with 4 so it remain 4 it doesn’t change
  2. const parametes are those whose value can’t be changed during entire program you can only access them

to declare a variable as const
just write const in front of data type
const int types

#3

in the first doubt i meant that we haven’t passed tyres while creating the object .??

#4

we are hardcoding its value
means we are not taking it from user and then assinging
we simply intialize it with 4 so no problem in it

#5
