Answer 1

Question 4:

• typedef is a feature which is used to create alias name for predefined datatypes or userdefined datatypes in c++.
• The alias name can then be used in the program instead of the datatype.
• Syntax : typedef datatype aliasname;

• typedef double A; = > A can be used instead of "double"
• typedef int B; = > B can be used instead of "int"

Question 5:

True

Memory that gets created dynamically is anonymous and hence it should be assigned to a pointer variable. The pointer variable is thus used to access the value stored in that memory address
