hello @tejuschaturvedi0

vectors are like array only

Size of arrays are fixed whereas the vectors are resizable i.e they can grow and shrink as vectors are allocated on heap memory. Arrays have to be deallocated explicitly if defined dynamically whereas vectors are automatically de-allocated from heap memory.

v.begin() gives iterator that points to the first element of vector.
v.end() gives iterator that points to address that is next of last element of vector.

check vector playlist of ur course for clarity
