My question is about function in c++

Recently, the world has been infected with Covid-19 pandemic. You as a programmer has
been asked by the Ministry of Health Malaysia to develop a system, that able to perform a
fast analysis to categorise whether the user has a Covid-19 symptom or not. The result of
the analysis will be based on the user’s inputs that correspond to several questions.
Finally, the system will display the result and accumulative numbers of the user that has a
Covid-19 symptom and no Covid-19 symptom.
i) Write the definition of the main()function.
• prompts the user to input his/her full name, address and age.
• calls the symptom() and pass age as an argument. The symptom() will
return a value and stored in a variable called finalResult.
• in each iteration, display the analysis’ result based on the conditions set in
Table 1.
• ask the user whether to repeat the process or not. If the user decided not to
repeat then display the total number of patients, the total number of Non-Covid-
19 patients and the total number of Covid-19 patients.
Table 1: Symptom decision result

Range of final result	Description of the result
0 ≤ ?inalResult ≤ 2	No COVID-19 symptom
2 < ?inalResult≤ 4	You had COVID-19 symptom
?inalResult < 0 OR ?inalResult > 4	The age entered is invalid

ii) Write the definition of the symptom() function.
• receives the age as a parameter from the main() function.
• calls the analysis() function with no argument. The analysis() function gets
called based on the conditions in Table 2 and will return a value stored in a variable
called total to this function.
• returns the value of the formula to the main() function.
Table 2: Range of patient’s age mapped to the mark of age

Range of age	Mark of age
0 < age ≤ 17	1
17 < age ≤ 55	0
55 < age ≤ 95	1
age < 0 OR age> 95	-1

Calculation formula: Mark of the age + total;

iii) Write the definition of the analysis() function.
• The analysis is performed according to several questions as shown in Table 3.
• the weighted from the user’s response will be used for the analysis calculation.
• returns the value of the formula given below to symptom() function.
Table 3: Question for analysis

Weighted from user’s respond
Question	Yes	No
1. Have you engaged with COVID-19 patient? [Y/N]	1	0
2. Have you got a fever? [Y/N]	1	0
3. Have you got breathing difficulties? [Y/N]	1	0

Calculation formula: Weighted Question 1 + Weighted Question 2 + Weighted Question 3;

Here's the sample output attached

Enter your name: Muhammad Imran bin Daud
Enter your address: 5, Lorong Haji Salleh
Enter your age: 21
Have you engaged with COVID-19 patient? [Y/N): N
Have you got a fever? [Y/N]: N
Have you got breathing difficulties? [Y/N): Y
---- Analysis Result
Name: Muhammad Imran bin Daud
Address: 5, Lorong Haji Salleh
Age: 21
COVID-19 Analysis Result: No COVID-19 symptom.
Thank You
Do you want to perform another analysis? [Y/N]: N
Total patients: 4
Total Non-COVID-19 patients: 2
Total COVID-19 patients: 2
