Is size_t same as unsigned int data type ?

Hello @asif_h yes correct.
it is just the alias.
Alias of one of the fundamental unsigned integer types.

It is a type able to represent the size of any object in bytes: size_t is the type returned by the sizeof operator and is widely used in the standard library to represent sizes and counts.
