Question

I am having trouble writing a code for the following problem in "Starting Out With C++ From Control Structures through objects"

In statistics, the mode of a set of values is the value that occurrs most often or with the greatest frequency. Write a function that accepts arguments as the following:

A) An array of integers
B) An integer that indicates the number of elements in the array

The function should determine the mode of the array. That is, it should determine which value in the array occurs most often. The mode is the value the function should return. If the array has no mode (none of the values occur more than once), the functions should return -1. (Assume the array will always contain nonnegative values).

Demonstrate your pointer prowess by using pointer notation instead of array notation in this function.

Explanation / Answer

Just declare an array (of some size). Then ask the user "How many numbers do you want to input?" If that's bigger than your array size, just print a message and exit. If the number of elements is input first, you don't need the realloc() stuff. You can go with simple malloc(). As long as you've learned pointers, that's enough. #include /* In statistics, the mode of a set of values is the value which occurs most often or with the greatest frequency. Write a function that accepts the following arguments: • An array of integers • An integer that indicates the number of elements in the array */ int meanArray(int arrayNum); int main() { int num; printf("How many numbers do you want to enter ? "); scanf("%i", &num); meanArray(num); return 0; } int meanArray(int arrayNum) { int makeArray[arrayNum]; return 0; }
