In this activity, you will implement and use several functions that use arrays as parameters. When passed as a parameter to a function, the function also needs to be told how large the array is; typically an integer size variable is passed with any array parameter. You will also declare and populate a static array to test your functions Instructions 1. A function, readInArray has been provided for you that takes an array and its size and prompts the user to enter values to populate the array. However, there is an error in the function: examine the scanf call and determine what is wrong and fix it before proceeding. Using the other functions as a reference, implement the getMin, getMax, and getMean functions. You will need to provide the correct function signature in both the header file and source file In the statsMain.c declare a static array that is "large enough" as indicated by the other clues in the code. Use your decared static array as an argument to readInArray and the other function calls Run your program and demonstrate it to a lab instructor. 2. 3. 4. Activity 4: Dynamic Arrays In this activity you will modify the code in statsMain.c to use a dynamic array instead of a static array Instructions 1. Alter your static array declaration to be an integer pointer and add code that calls malloc to initialize the appropriate amount of memory Alter any other code as necessary to remove the "large enough" restriction that we had in the previous activity 2. 3. Run your program again and demonstrate it to lab instructor Lab Handout: Arrays & Dynamic Memory Follow Up Demonstrate your program using a "large" array. Obviously prompting for and entering a lot of numbers is tedious. So instead, alter your code again to instead take advantage of the createRandomArray function provided for you. Demonstrate it to a lab instructor and have them sign your lab worksheet.

Explanation / Answer

void readInArray(int* arr, int size)

{
int i;
printf("Enter your list of numbers: ");
for (i = 0; i < size; i++) {
scanf("%d", arr[i]);
}
return;
}

void readInArray(int* arr, int size) ;

now check code once
