Summary In this lab, you complete a partially prewritten C++ program that uses an array. The program prompts the user to interactively enter eight batting averages, which the program stores in an array. The program should then find the minimum and maximum batting average stored in the array as well as the average of the eight batting averages. The data file provided for this lab includes the input statement and some variable declarations. Comments are included in the file to help you write the remainder of the program. Instructions Ensure the source code file named BattingAverage.cpp is open in the code editor. Write the C++ statements as indicated by the comments. Execute the program by clicking the Run button. Enter the following batting averages: .299, .157, .242, .203, .198, .333, .270, .190. The minimum batting average should be .157, and the maximum batting average should be .333. The average should be .2365. I entered the question below and that was previously answered…

Programming Language: C++ I really need help with this question and I keep getting repost answers. Please, someone, help with a genuine understanding of the problem. Code two functions to fill an array with the names of every World Series-winning team from 1903 to 2020, then output each World Series winner with the number of times the team won the championship as well as the years they won them. The input file is attached, along with the main function and screenprint. Please note team names that include two words, such as Red Sox, have an underscore in place of the space. This enables you to use the extraction operator with a single string variable. The following resources are included: Here is main. #include <iostream>#include <fstream>#include<string> using namespace std; // Add function declarations and documentation here void fill(string teams[], int size);void findWinner(string teams[], int size); int main(){ const int SIZE = 118;int lastIndex;string team[SIZE];…
