Chapter 3, Problem 3RQE
Explanation of Solution
Header files:
It contains function definitions and variables, which are imported into any C++program by using the “#include” statement.
- It has an extension “.h”, which contains function prototype and macro definition.
- The given code requires two header files. They are:
<iostream>
<iomanip>
“iostream” file:
In given code, it has “cout” variable, which is used to display the program output. It has been defined in “iostream” file and for the type “ostream” object.
- Hence, it is necessary to include <iostream> file.
“iomanip” file:
The given code also contains “setw()” function, which is used to set the corresponding field width for output operation...

You need to modify a program to take all the information (jersey number, name, height, accuracy and yearly salary) of each player and find the information of the best player who has best accuracy among them. You should consider the accuracy in a range [0-10]. Take all the information using a struct data type in C++. Like, struct teamDetroit { int jersey_num[10]; string name[10]; double height[10]; float accuracy[10]; int salary[10]; }; Moreover, take only 3 players information and put the player name as a single name (either first_name or last name).
