Question

You will be writing an electronic bowling scoring program using functions, arrays, and structures. Refer to the following website for the rules of scoring: http://en.wikipedia.org/wiki/Ten-pin_bowling

The program should allow multiple players (at most 10) to play the bowling game and keep track of each player’s score. In addition, the program should allow players to play the bowling game as many times as they want. The game consists of 10 frames. During each frame, a random number generator will generate numbers which will be used to calculate the score for that frame. At the end of each frame, your program should display the individual score for each frame that has been completed so far and the running total score. If a frame’s score is not available at the end of that frame, use “strike” or “spare” to indicate its status.


The following is an example program that generates a random number from 1 to 10.

#include
#include
using namespace std;
int main()
{
//declare variable to hold random number
int random;

//randomize number based on time
srand(time(NULL));

//generate random number from 1 to 10
random = rand() % 10 + 1;

cout<
return 0;
}
