Question

an intensive care unit of Hospital Sg Buloh keeps information on the patients suffering from Covid 19in the following input file named covid.txt. The file contains the patient's gender, name, age and number of days in ward followed by daily temperatures for 50 patients. The symbol ';' indicate the delimiter of the data.

female; Mariam Binti Ramli; 20 4 39.0 39.0 38.5 37.0

female; Aisyah Binti Salleh; 41 3 41.0 39.0 38.0

male; Nuh Harraz bin Amirul; 35 5 41.0 41.0 40.5 40.5 39.0

: : covid.txt

**COULD YOU JUST SHOW ME A COMPLETE PROGRAM FLOWCHART FOLLOWS ALL THE QUESTIONS BELOW INSTEAD OF WRITING THE C++ PROGRAM**

a) Define a record name Covid19 to store patients information as follows:

Patient's gender Patient's name

Patient's age

Number of days in the ward

daily temperature

b) Declare an array named patientInfo of type Covid19 with size 50

c) Read all data from covid.txt

d) Find the total number of male and female patients suffering from covid19

e) Find the youngest and oldest patient's age

f) Find the name of patient whose lengthof stay in the ward is the longest. Display also the days and the number of days temperature above 40.

g) Write all the output into the name summary.txt. A sample output file is given below:

Summary of Covid19 patients:

Total number of male patients: 48 Total number of femal patients: 50

The youngest patient age: 25 {male} The oldest patient age: 65 {male}

The longest length of stay in the ward is 14 days with 7 days temperature above 4*C.

The patient's name is Liman Bin Hafizi {male, 65 years old}.

PLEASE KINDLY EXPLAIN THE FLOWCHART FOR THIS PROBLEM.

Answer 1

Note:

I have some doubt regarding the temperatures above 40...I will check and update that code too...Thank u

=================================

We have to paste the input file in the project folder so that our program can able to detect.
