Expert Solution & Answer
Chapter 23, Problem 12RE
Explanation of Solution
Justification:
- The “flush ()” method is being used for flushing out the internal buffer which could be used.
- Print writers buffer their outputs. They will not send the characters in the buffer until the buffer is full.
- For example, using “BufferedOutputStream” would have content for jotting the chuck for enhancing the performance of the system...

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.
