Name: Lab9_1 Array Builder Description: Dynamically allocates a new integer array or larger integer arrayLimitations:Credits:
Includes mandatory file header:- uses empty Win32 Console Application:- Programs submitted with correct folder structure and correct files (cpp & h):user Interface (10%):———————- Clean easy-to-use:- Informed user of application:- Prompted user for input data:- Leaves cursor at end of line prompting input:- Correct spelling in user interface: Source Code Formatting (40%):—————————— Descriptive Names for functions and variables:- Correct Use of Indentations:- Effective use of newlines:- Use of local variables:- Misuse of global variables:- Effective use of comments:- Use of constants and enums:Demo Results (40%):——————– Compiles w/o errors:- Instructor pause included in all return paths:- Input validation done according to requirements:- Produced expected program output:-
