Answer to Question #237655 in C++ for sandyJay

Question

Create a programm that will determine there correct vaccine for every candidate. Use the switch statement and the for loop to determine the right vaccine for individuals by using their temperature readings

-30-33 for Mordena

-34-36 mRNA

-37-38 Johnson and Johnson’s Janssen

-39-40 Pfizer-BioNTech

The program must be able to read temperatures up to four(4) decimal places after the comma & convert it to two(2) decimals. A summary of all the people that are vaccinated along with their associated vaccines must be listed in the output in a table form as follows:

Name and surname Temperature Vaccine

Mzamani Nkuna 34,37 mRNA

Themba Manana 37,66 Johnson and johnson’s Janssen

Charles Nkosi 32,55 Mordena

Norwell Mbewe 39,78 pFizer-BioNTech

Take note of the following :

1. Use an appropriate operator to convert an expression to a specified type.

2. Use an appropriate operator to set correct precision for decimals

3. Use an appropriate operator to manage the alignments in the summary of your candidates

Answer 1

#include <iostream>
#include <string>
#include <iomanip>


using namespace std;


struct Candidate{
	string fullName;
	float temperature;
	string vaccine;
};


int main(){
	int numberCandidates=-1;
	while(numberCandidates<=0){
		cout << "Ente the number of candidates: ";
		cin>>numberCandidates;
	}
	Candidate* candidates=new Candidate[numberCandidates];
	for(int i=0;i<numberCandidates;i++){
		cin.ignore();
		cout << "Ente the name and surname of candidate "<<(i+1)<<": ";
		getline(cin,candidates[i].fullName);
		cout << "Ente the temperature of candidate "<<(i+1)<<": ";
		cin>>candidates[i].temperature;
		switch ((int)candidates[i].temperature)
		{
			//-30-33 for Mordena
		case 30 ... 33:
			candidates[i].vaccine="Mordena";
			break;
			//-34-36 mRNA
		case 34 ... 36:
			candidates[i].vaccine="mRNA";
			break;
			//-37-38 Johnson and Johnson’s Janssen
		case 37 ... 38:
			candidates[i].vaccine="Johnson and Johnson’s Janssen";
			break;
			//-39-40 Pfizer-BioNTech
		case 39 ... 40:
			candidates[i].vaccine="Pfizer-BioNTech";
			break;




			break;
		}
	}


	cout<<fixed<<left<<setw(30)<<"Name and surname"<<setw(30)<<"Temperature"<<setw(30)<<"Vaccine\n";
	cout<<"\n";
	for(int i=0;i<numberCandidates;i++){
		cout<<setw(30)<<candidates[i].fullName<<setw(30)<<setprecision(2)<<candidates[i].temperature<<setw(30)<<candidates[i].vaccine<<"\n";
	}
	delete[] candidates;
	cin>>numberCandidates;
	return 0;
