Question

Posted this a few hours ago. Can anyone help with this? IN C++ Perform the following: Read 10 bowlers with 3 scores each into 1 string array and 1 numeric array(2 dimension double array) Sort the data by individual bowlers averages, Don't forget to sort their names also. Calculate the average across and store in your existing array. Calculate the average down and store in your existing array. Print out the contents of both arrays. This will print the averages across and down also. Search for a bowler (bowler named keith) print his 3 scores and averages. Instead of sorting by name, i need to sort by the averages of the individual bowlers...the average that was calculated across in the original problem. I would like to do it using bubble sort. I should print out all of the bowlers with their averages across and down and sorted by the averages that print out across. Here is the code i have so far but this sorts by name.

#include //to use cout and cin and endl// allows using cout without std::cout
#include // to use string data type
#include //to use strlen, strcmp, strcpy
#include    //for pow function,sqrt,abs
#include // for set precision, setw,
#include //for file input
#include // to use assert to disable place before #define NDEBUG
#include //for random numbers, exit function
#include //time function used for rand seed
#include // for toupper, tolower

Answer 1

The program that you've written is logically correct and should work. The sorting must be performed on the averages of the players.
