Question

The Canadian government wants to keep track of how many masks and protective gowns are available in each hospital. There is a text file called F: equipment.txt that contains this data. Each line in the file uses this format:

hospital name;number of masks;number of gowns

For example, the first four lines in the file look like this:

burnaby;495;483

Vancouver;872;791

Victoria;361;361

Calgary;476;502

Note that the hospital names are not in any particular order in the file.

Each hospital should have the same number of masks and gowns. Write a C program that reads all the data from the file and displays each hospital with the number of items that are needed to make the two numbers the same. When your program is running the screen should look something like this:

Items to be supplied to each hospital:

Vancouver 81 gowns

Calgary 26 masks

Burnaby 12 gowns

Victoria no items needed

The hospital names must be displayed in alphabetical order.

Answer 1

If you will feel any problem with the solution, then feel free to ask it in comments.

Happy Learning

1. You ask for The hospital names must be displayed in alphabetical order.

2. But your output not follows it.

Finally, I choose to print in alphabetical order.

#include<stdio.h>

#include<string.h>

#include<ctype.h>

// Hospital type structure

typedef struct Hospital

{

char name[20];

int masks;

int gowns;

int required;

char required_item_name[20];

}Hospital;

// sort hosp array in increasing order with respect to name

void sort(Hospital *hosp, int no_of_hosp)

{

int i, j;

Hospital temp;

for(i=0; i<no_of_hosp-1; ++i)

{

for(j=0; j<no_of_hosp-i-1; ++j)

{

if(strcmp(hosp[j].name, hosp[j+1].name)>0)

{

temp = hosp[j];

hosp[j] = hosp[j+1];

hosp[j+1] = temp;

}

}

}

}

// calculate mask required or gown required

void calculate(Hospital *hosp, int no_of_hosp)

{

int i;

char masks[] = "masks";

char gowns[] = "gowns";

for(i=0; i<no_of_hosp; ++i)

{

// if mask > gown, then gowns required

if(hosp[i].masks>hosp[i].gowns)

{

hosp[i].required = hosp[i].masks - hosp[i].gowns;

strcpy(hosp[i].required_item_name, gowns);

}

// if mask < gown, then masks required

else if(hosp[i].masks<hosp[i].gowns)

{

hosp[i].required = hosp[i].gowns - hosp[i].masks;

strcpy(hosp[i].required_item_name, masks);

}

// if mask == gown, then nothing required

else

{

hosp[i].required = 0;

}

}

}

// display hosp array in given format

void display(Hospital *hosp, int no_of_hosp)

{

if(hosp[i].required == 0)

{

printf("%s no items needed\n", hosp[i].name);

}

else

{

printf("%s %d %s\n", hosp[i].name, hosp[i].required, hosp[i].required_item_name);

}

}

}

void main()

{
