/*
Vamos a modificar el programa anterior para trabajar con tablas de estructuras, de forma que
calculemos el KDA total de los cinco jugadores que han participado en la partida.
Para obtener dicho dato es necesario sumar por un lado los asesinatos de los cinco jugadores,
por otro las muertes y finalmente las asistencias. Asimismo,
calcularemos el ratio de ese KDA total.
------------------------------resuelto por pasos--------------------------------
1)Definir dos constantes a la cual le pasaremos por valor la longitud de los vectores que crearemos mas adelante (opcional)
2)Crear una estructura con las variables necesarias para almacenar los datos requeridos.
a) los datos requeridos son:
*)Nombre
*)Nombre del campeon
*)Asesinatos
*)Muertes
*)Asistencias
b) ejemplo de codigo:
typedef struct {
char name[10];
char champion[10];
int kills;
int deaths;
int assists;
} players;
3)Crear una tabla estructurada para poder almacenar los datos de los jugadores.
*)ejemplo en codigo:
players game[5];
4)Solicitar los datos que almacenaremos en las variables de la estructura creada previamente, sacar el ratio de de KDA y mostrar el ratio por pantalla.
a) solicitar datos:
*)Ejemplo en codigo:
printf("Name: ");
scanf("%s", &game[0].name);
printf("Champion: ");
scanf("%s", &game[0].champion);
printf("kills: ");
scanf("%d", &game[0].kills);
printf("deaths: ");
scanf("%d", &game[0].deaths);
printf("assists: ");
scanf("%d", &game[0].assists);
// y asi hasta completar todos los jugadores
b)Sacar ratio y motrarlo por pantalla
*)Ejemplo en codigo:
float player1_ratio = (float)(game[0].kills + game[0].assists)/game[0].deaths;
printf("Ratio player1 %f\n", player1_ratio);o);
// repetir con el resto de jugadores
5)Sumar el KDA de todos los jugadores, sacar el ratio de ese KDA y mostrarlo por pantalla.
a)Sumar KDA y sacar el ratio
*)ejemplo de codigo:
int total_kills = game[0].kills + game[1].kills + game[2].kills + game[3].kills + game[4].kills
int total_deaths = game[0].deaths + game[1].deaths + game[2].deaths + game[3].deaths + game[4].deaths
int total_assists = game[0].assists + game[1].assists + game[2].assists + game[3].assists + game[4].assists
total_ratio = (float)(total_kills + total_deaths) / total_assists
b) mostrar por pantalla el nombre de los jugadores, el kda total y ratio de ese kda total
*)ejemplo en codigo:
printf("Players %s%s%s%s%s have kda: %d/%d/%d and ratio: %f", game[0].name, game[1].name, game[2].name, game[3].name, game[4].name, total_kills, total_deaths, total_assists, total_ratio)

DESCRIPTION:
Read one or more matrices from an input
Each matrix should be separated by a blank line or a line whos first character is "# followed by an identifier number"
Data is stored as a continuous array of double-precision floating point numbers
Automatically detects the number of rows and columns in the input
- the first matrix is taken as the model - discrepancies result in errors
The number of matrices and the number of rows and columns are stored
NOTE: multiple whitespace is treated as a single whitespace, so "empty"
words in a line will affect the index to all subsequent columns.
USES:
storing 2-d blocks of ASCII data into memory as a 1d array
DEPENDENCIES:
char *xf_lineread1(char *line, long *maxlinelen, FILE *fpin);
ARGUMENTS:
char *infile - name of the input file, or "stdin"
long idcol - for lines starting with "#", the zero-offset column-number holding the id (typically "1")
double **matrix1 - result, multi-matrix data - freed by calling function
double **id1 - result, id's for each matrix - freed by calling function
long *ncols - result, how many columns are on each row of each matrix
long *nrows - result, how many rows are in each matrix
char *message - holds error messages - should be defined by calling funtion as message[256]
FILE *fpin - pointer to input stream (typically a file or stdin) - updated by the function
RETURN VALUE:
- the number of matrices detected, or -1 on error
- the matrix1[] array is filled
- the id1[] array stores the identifiers for each matrix, presuming they are preceded by a "# <identifier>" line
- the message[] array will hold any errors
SAMPLE CALL:
char message[256];
double *matrix1=NULL, *id1=NULL, *pmatrix;
long nmatrices,ncols,nrows,ii,jj,kk,mm,idcol=1;
nmatrices= xf_matrixread1_d(&matrix1,idcol,&id1,&ncols1,&nrows1,message,fpin);
mm=5;
pmatrix= matrix1+(mm*ncols*nrows); // select fifth matrix
printf("# %g\n",id1[mm]); // print the identifier
for(ii=0;ii<nrows;ii++) {
for jj=0;jj<ncols;jj++) printf("%g ",pmatrix[ii*ncols+jj]);
