 Hello Friends this is our first blog

1. Input iterator:
   • An Input iterator is an iterator that allows the program to read the values from the container.
   • Dereferencing the input iterator allows us to read a value from the container, but it does not alter the value.
   • An Input iterator is a one way iterator.
   • An Input iterator can be incremented, but it cannot be decremented.
2. Output iterator:
   • An output iterator is similar to the input iterator, except that it allows the program to modify a value of the container, but it does not allow to read it.
   • It is a one-way iterator.
   • It is a write only iterator.
3. Forward iterator:
   • Forward iterator uses the ++ operator to navigate through the container.
   • Forward iterator goes through each element of a container and one element at a time.
4. Bidirectional iterator:
   • A Bidirectional iterator is similar to the forward iterator, except that it also moves in the backward direction.
   • It is a two way iterator.
   • It can be incremented as well as decremented.
5. Random Access Iterator:
   • Random access iterator can be used to access the random element of a container.
   • Random access iterator has all the features of a bidirectional iterator, and it also has one more additional feature, i.e., pointer addition. By using the pointer addition operation, we can access the random element of a container.
