Objectives:
• Learn more about pointers and arrays
Description:
• Modify your functions from the pre-lab 4: createIntArray, getArraySize, and freeArray.
• In createIntArray function, create an array of integers where 1 ≤ array[i] ≤ 20, using rand function.
• Store maximum value of the array at “array[-1]”, store the size of the array at “array[-2]”, and store the elements starting from “array[0]”.
After updating your createIntArray(), your array should look like below:
array[-2]
array[-1]
array[0]
array[1]
array[2]
array[3]
…
array[18]
array[19]
Size Max_Value
Main function steps:
• Call createIntArray function.
• Call getSizeArray and assign its return value to a variable called size2
• Print your array, array size, and a maximum integer in the array as shown in Example output below.
• Free the created array using your freeArray function.
Every user-defined function must have a comment describing:
• What function does;
• What parameter values are;
• What value it returns.
Example output:
Please enter an array size: 8
Array: [ 11 12 15 1 6 9 13 12 ]
My array size from getArraySize() is 8.
Max value: 15
Function Prototypes:
• int* createIntArray(int arraySize);
• int getArraySize(int* array);
• void freeArray(int* array);
Grading Criteria:
