Question

(a) Declare suitable C datatypes to represent each of the following sets of informa-

tion (as you would do in a header file):

(i) A company, described by:

• A 3-letter code.

• The current share price (a positive real number).

• The total number of shares (a positive integer).

• Total asset value (a positive real number).

• Total debts (a positive real number).

ii) A consortium of companies, including:

• A set of core member companies.

• A set of associate member companies.

FILE fopen (const char *path, const char *mode); int fclose (FILE fp); int fscanf (FILE *stream, const char *format, char *fgets(char *s, int size, FILE *stream); int feof (FILE stream); int strcmp (const char *s1, const char *s2); char *strcpy (char *dest, const char src);

Explanation / Answer

here is your answer : ------------>>>>>>>>

#include<stdio.h>
#include<string.h>

/* Answer to Question A */
typedef struct Company_{
char code[4];
double currentSharePrice;
unsigned int totalNumberOfShares;
double totalAssets;
double totalDebts;
}Company;

typedef struct Consortium_{
Company *core;
//for keep track of core company
int numCore;
Company *ass;
//for keep track of Associate Company
int numAss;
}Consortium;

/* End of question A */

  return NULL;
