Chapter 18.1, Problem 6SCP
Explanation of Solution
“mod” hash function and chaining:
- This type of storing system is preferred over array implementation as it takes care of the issues faced in implementing the array sorting.
- With the use of “mod” hash function, it is easy to store the elements in the respective indexes.
- The index values of the values are derived with the use of “mod” function.
- In this method, the element value is sent to the index that is derived by modding the element’s value by the array capacity.
- Example: if the length of the array is given as “10” and the element that has to be stored is “23” then, the value “23” is inserted at index 3.
- In this case, the negative values are assigned by finding out the absolute value of the element and then assigning it to its mod value.
- Collision is one of the risks faced in this method, which occurs when two or more values are to be inserted at the same index value...

You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array. Do not hard code your solution! If we test your code with different array values, we should still get the correct output.
