If we want a search function to search an array for some value and return either the index where the value was found, or -1 if not found, which of the following prototypes would be appropriate?

B) void searchconst int array, int target);
C) int searchconst int array[], int numElements);
D) int searchconst int array[], int target, int numElements);

Option A is incorrect because it returns void instead of an index or -1.
Option B is also incorrect because it does not have the parameter for the number of elements in the array.
Option C is incorrect because it does not have a parameter for the target value and does not return -1 if the target is not found.
Option D is the correct answer because it takes in an array, the target value, and the number of elements in the array. It also returns the index where the target value was found, or -1 if it was not found.
