#include <iostream>
#include <iomanip>
#include <string>
#include <vector>
using namespace std;
class Food{
public:
vector <int> pizzaID;
vector <int> pastaID;
vector <int> drinksID;
vector <string> pizzaName;
vector <string> pastaName;
vector <string> drinksName;
vector <double> pizzaPrice;
vector <double> pastaPrice;
vector <double> drinksPrice;
Food() :
pizzaID(), pastaID(), drinksID(),
pizzaName(), pastaName(), drinksName() {}
void defaultFood(){
pizzaID.push_back(1);
pizzaID.push_back(2);
pizzaID.push_back(3);
pizzaID.push_back(4);
pizzaID.push_back(5);
pizzaName.push_back("Beef Pepperoni");
pizzaName.push_back("Chicken Pepperoni");
pizzaName.push_back("Cheese Pepperoni");
pizzaName.push_back("Island Supreme");
pizzaName.push_back("Seafood Supreme");
}
void displayPizza(){
for(int n=0; n<pizzaID.size(); n++){
cout<<setw(2)<<pizzaID[n]<<" "<<pizzaName[n];
cout<<setw(20)<<"RM"<<endl;
}
}
};
int main(){
Food f;
f.defaultFood();
f.displayPizza();
}

This is the output for the code:
1
2
3
4
5
|
1 Beef Pepperoni RM25.00
2 Chicken Pepperoni RM25.00
3 Cheese Pepperoni RM20.00
4 Island Supreme RM22.00
5 Seafood Supreme RM25.00
|
This is the output that I want:
1
2
3
4
5
|
1 Beef Pepperoni RM25.00
2 Chicken Pepperoni RM25.00
3 Cheese Pepperoni RM20.00
4 Island Supreme RM22.00
5 Seafood Supreme RM25.00

I'm not sure what to use in order to get what I want. Need suggestion. Thanks!

cout << left << setw(2) << pizzaID[n] <<" "<< setw(20) << pizzaName[n] <<"RM "<<endl;

setw() sets the maximum width to be taken by the next value inserted, by default it is aligned to the right, so which
left formatter comes handy
