Counting Vectors

[Devynao]

So I've done some research, and found out I cant count them because it is a type. I cannot figure out how to count whats in it or if I am even thinking of this correctly. I am trying to display the total amount of jobs.

I was previously having trouble getting to get the jobs to display like a list. This code fixed that.

  for (const auto & elem : jobs) {
		system ("CLS");	
		cout << "Customer Name     " << "     Job Name" << endl;

		for (int x = 0; x != jobs.size (); ++x) {
			cout << jobs[x] << endl;
		}

Here is my full code.

#include <iostream>
#include <string>
#include <vector>
#include <utility>
#include <iomanip>
using namespace std;

struct PrintJobs {
	string m_customer = " ";
	string m_jobName = " ";
	int m_front = 0;
	int m_back = 0;
	int m_day = 1;
	int m_quanity = 0;
	//bool m_flash;
	char m_type;
};
ostream& operator << (ostream& os, const PrintJobs& pJ) {
	os.width (23);
	os << left << pJ.m_customer;
	os.width (26);
	os << left << pJ.m_jobName;
	os.width (13);
	os << left << pJ.m_quanity;
	os.width (10);
	os << left << pJ.m_front;
	os.width (10);
	os << left << pJ.m_back;
	//os.width (10);
	//os << left << pJ.m_flash;
	os.width (15);
	os << left << pJ.m_type;
	os.width (10);
	os << left << pJ.m_day;
	return os;
}

int main () {
	bool fQuit = false;
	vector<PrintJobs> jobs{};
	while (!fQuit) {
		cout << "1. Enter job \t2. Show all jobs \t3. Search jobs by day \t4. Quit";
		cout << "\nEnter your choice \n";
		int choice{};
		cin >> choice;//input validation required
		cin.ignore ();
		switch (choice) {
		case 1:
		{
			PrintJobs temp{};
			cout << "Customer name \n";
			getline (cin, temp.m_customer);
			cout << "Job name \n";
			getline (cin, temp.m_jobName);
			cout << "Quanity \n";
			cin >> temp.m_quanity;
			cout << "Front \n";
			cin >> temp.m_front;
			cout << "Back \n";
			cin >> temp.m_back;
			//cout << "Flash y/n \n";
			//cin >> temp.m_flash;
			cout << "Type \n";
			cin >> temp.m_type;
			cout << "Enter day number (Mon(1), Tue(2), Wed(3), Thu(4), Fri(5), Sat(6), Sun(7)) \n";
			cin >> temp.m_day;
			cin.ignore ();
			jobs.push_back (move (temp));
			system ("PAUSE");
			system ("CLS");
		}
		break;
		case 2:
		{
			if (jobs.size () == 0) {
				cout << "No jobs to display \n";
				system ("PAUSE");
				system ("CLS");
			}
			else {
				
				for (const auto & elem : jobs) {
					system ("CLS");	
					cout << "Customer Name     " << "     Job Name" << endl;

					for (int x = 0; x != jobs.size (); ++x) {
						cout << jobs[x] << endl;
					}

					//cout << elem << endl << endl;
					
					system ("PAUSE");
					system ("CLS");
				}
			}
		}
		break;
		case 3:
		{
			if (jobs.size () == 0) {
				cout << "No jobs to search \n";
				system ("PAUSE");
				system ("CLS");
			}
			else {
				cout << "Enter day number to search: (Mon(1), Tue(2), Wed(3), Thu(4), Fri(5), Sat(6), Sun(7)) \n";
				int daySearch{};
				cin >> daySearch;
				cin.ignore ();
				cout << "Searching ... \n";
				bool match = false;
				for (const auto & elem : jobs) {
					if (elem.m_day == daySearch) {
						cout << elem << "\n";
						match = true;
					}
				}
				if (match == false) {
					cout << "No matches were found \n";
					system ("PAUSE");
					system ("CLS");
				}
			}
		}
		break;
		case 4:
			fQuit = true;
			cout << "Goodbye \n";
			break;
		default:
			cout << "Incorrect choice, try again \n";
			break;
		}
	}
}

Something like this, perhaps:

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

struct PrintJobs {

	std::string m_customer ;
	std::string m_jobName ;
	int m_front = 0;
	int m_back = 0;
	int m_day = 1;
	int m_quanity = 0;
	char m_type = 'X' ;
};

std::ostream& operator <<( std::ostream& os, const PrintJobs& pJ ) {

	return os << std::setw(20) << pJ.m_customer
	          << std::setw(25) << pJ.m_jobName
	          << std::setw(8) << pJ.m_quanity
	          << std::setw(8) << pJ.m_front
	          << std::setw(8) << pJ.m_back
	          << std::setw(6) << pJ.m_type
	          << std::setw(8) << pJ.m_day ;
}

std::ostream& print_header( std::ostream& os ) {

	return os << std::setw(20) << "customer"
	          << std::setw(25) << "job name"
	          << std::setw(8) << "quanity"
	          << std::setw(8) << "front"
	          << std::setw(8) << "back"
	          << std::setw(6) << "type"
	          << std::setw(8) << "day"
	          << '\n' << std::string( 90, '-' ) << '\n' ;
}


int main() {

    std::vector<PrintJobs> jobs { { "customer one", "job one", 1, 2, 3, 4, 'A' },
                                  { "customer two", "job two", 5, 6, 7, 8, 'B' },
                                  { "customer three", "job three", 9, 10, 11, 12, 'A' },
                                  { "customer one", "job four", 13, 14, 15, 16, 'C' },
                                  { "customer two", "job five", 17, 18, 19, 20, 'B' }
                                } ;
    int total_quanity = 0 ;

    std::cout << "     " ;
    print_header(std::cout) ;

    int slno = 0 ;
    for( const auto& j : jobs ) {

        std::cout << std::setw(3) << ++slno << ". " << j << '\n' ;
        total_quanity += j.m_quanity ;
    }

    std::cout << "\ntotal number of jobs:" << std::setw(5) << jobs.size()
              << "\n       total quanity:" << std::setw(5) << total_quanity << '\n' ;
}
