Built-in Functions
Built-in functions are available by default, without importing any package. Their names are predeclared function identifiers. They give access to Go's internal data structures. Their semantics depends on the arguments.

len()
len() returns string length, array length, slice length and map size.
cap()
cap() returns slice capacity.
Complex Number Manipulation
TO DO: Continue to Distribute These Built-in Functions
Allocation: new()
Making slices, maps and channels: make()
Appending to and copying slices: append(), copy()
Deletion of map elements delete()
Handling panics panic(), recover()
