C2A5E2 (6 points - Program) Exclude any existing source code files that may already be in your IDE project and add a new one, naming it C2A5E2_Create2D.c. Also add instructor-supplied source code files C2A5E2 Type-Driver.h and C2A5E2_main-Driver.c. Do not write a main function! main already exists in the instructor-supplied implementation file and it will use the code you write. Regarding data type Type, which is used in this exercise... Type is a typedef'd data type that is defined in instructor-supplied header file C2A5E2_Type-Driver.h Any file that uses this data type must include this header file using #include. File C2A5E2_Create 2D.c must contain functions named Create2D and Free2D. Create2D syntax: Type **Create2D(size_t rows, size_t cols); Parameters: rows - the number of rows in the 2-dimensional pointer array Create2D will create cols - the number of columns in the 2-dimensional pointer array Create2D will create Synopsis: Creates a 2-dimensional pointer array of data type Type having the number of rows and columns specified by rows and cols. All memory needed for this array is dynamically-allocated at once using a single call to the appropriate memory allocation function. If allocation fails an error message is output to stderr and the program is terminated with an error code. Return: a pointer to the first pointer in the array Free2D syntax: void Free2D(void *p); Parameters: p-a pointer to the block of memory dynamically-allocated by Create2D Synopsis: Frees the dynamically-allocated block of memory pointed to by p. Return: vold Submitting your solution Send all three source code files to the assignment checker with the subject line C2A5E2_ID, where ID is your 9-character UCSD student ID.
