C++ Vector cbegin()
This function is used to point the first element of the vector container.
cbegin() vs begin()
The cbegin() function returns the constant iterator while begin() function returns an iterator. The element pointed by the end() function can be modified but not by cend() function.
Consider a vector 'v'. Syntax would be:
It does not contain any parameter.
It returns the constant iterator pointing to the first element of the vector.
Let's see a simple example.
In this example, it shows an error as we are trying to modify the value using cbegin() function which is not possible in this case.
Let's see a another simple example.
In this example, cbegin() function is incremented by 1 to access the second element of the vector.
