Question

Suppose you have to enter five customers in a bank. The bank counter comprises of three service desk so three rows and three columns were made. Write a C++ program to provide service for customers according to row and column. First customer will stand in the first row first column, then the next customer in the first row second column and so on. Create a function which takes total number of customers as input as an argument and display the seating plan using another function.

Answer 1

#include<iostream>
#include<vector>

using namespace std;

//Seating plan function 
void SeatingPlan(vector<vector<char> > desks)
{
	cout<<"\nSeatingPlan:\n";
	cout<<"Col:   1  2  3\n";
	for(int i=0;i<3;i++)
	{
		cout<<"Row "<<i+1<<": ";
		for(int j=0;j<3;j++)
		{
			cout<<desks[i][j]<<"  ";
		}
		cout<<endl;
	}
}

void Customers(vector<vector<char> >& desks,int num)
{
	if(num>9||num<0)
	{
		cout<<"Incorrect number of customers!";
		return;
	}
	int counter=0;
	for(int i=0;i<3;i++)
	{
		if(counter>num)
			break;
		for(int j=0;j<3;j++)
		{
			if(counter<num)
			{
				desks[i][j]='X';
				counter++;
			}
			else
				break;
			
		}
	}
}

int main()
{
	vector<vector<char> > d(3,vector<char>(3,'0'));
	int n;
	SeatingPlan(d);
	cout<<"Please, enter the number of customers: ";
	cin>>n;
	Customers(d,n);	
	SeatingPlan(d);
}
