Hi everyone, Im new to the community and was just wondering if I could get some help :)
I have an assignment where i have to create a program for a shipping company and I was wondering if someone could help me with the coding to assign the sum of a value to my array.
In line 75 after it says Freight Id is: I want to be able to assign the result of case 1 to any number in int freightId and then display it after.

#include <iostream>
#include <iomanip>
#include <ctime> 
#include <cstdlib>
using namespace std;

double shipcharge(double kg,int miles)
{
       
	double sc;
	int p1=(miles/500);
	if (miles%500>0)p1++;
	if(kg<=2)sc=1.1*p1;
	else if(kg<6)sc=2.2*p1;
	else if(kg<10)sc=3.7*p1;
	else if(kg<=20)sc=4.8*p1;
	return sc;
}

int main()
{
   int choice;       // Menu choice

   int freightId [] = { 1721, 1722, 1723, 1724, 1725, 1726, 1727, 1728, 1729, 1730, 1731, 1732, 1733, 1734, 1735, 1736, 1737, 1738, 1739, 1740, 1741, 1742, 1743, 1744, 1746, 1747, 1748, 1749, 1750, 1751, 1752, 1753,1754, 1755, 1756, 1757, 1758, 1759, 1760, 1761, 1762, 1763, 1764, 1765, 1766, 1767, 1768, 1769, 1770, 1771, 1772, 1773, 1774, 1775, 1776, 1777, 1778, 1779, 1780, 1781, 1782, 1783, 1784, 1785, 1786, 1787, 1788, 1789, 1790, 1791, 1792, 1793, 1794, 1795, 1796, 1797, 1798, 1799, 1800, 1801, 1802, 1803, 1804, 1805, 1806, 1807, 1808, 1809, 1810, 1811, 1812, 1813, 1814, 1815, 1816, 1817, 1818, 1819, 1820 };
   

   int d=0,cnt=0 , miles;
	double kg  ;
	double w;


  cout << "\t\tWelcome to FastFreight Company. You can select option from 1-5.\n\n";
   cout << "1. Add Freight Order\n";
   cout << "2. Update Status\n";
   cout << "3. Display Freight Voucher\n";
   cout << "4. Display Freight Order\n";
   cout << "5. Exit the System\n\n";
   cin >> choice;
   
   // Set the numeric ouput formatting.
   cout << fixed << showpoint << setprecision(2);
   
   // Respond to the user's menu selection.
   switch (choice)
   {
      case 1:
         cout << "Weight of Package: ";
         cin >> kg;
         w = kg;
         if (w <=0 )
		{
			cout<<"Please enter weight between 0-20.\n";
            cin>> kg;
		}
		
	else if ( w > 20)
		{
			cout<<"Please enter weight between 0-20.\n";
			cin>> kg;
		}
         cout << "Distance to be sent:";
         cin >> miles;
         d = miles;
         if (d<10)
		{
			cout<<"Please enter distance between 10-3000.\n";
		    cin>> kg;
		}
	else if(d>3000)
		{
			cout<<"Please enter distance between 10-3000.\n";
			cin>> kg;
		}
         cout<<"Cost for "<<w<<" kg for "<<d<<" miles is $"<<fixed<<shipcharge(w,d)<<endl;
         cout<< "Frieght ID is: "<< <<endl;
         
         cnt++;
         break;

why do you need that array? they are all consecutive numbers, so you should be able to just calculate the value of freight id based on something else. I have no idea how you can derive freight id from the rest of the data objects in that program. Are you missing something from the assignment?

Sorry about the following syntax but you can solve it by this way :

int freightId [] = { 1721, 1722, 1723, 1724, 1725, ...} actually means

freightId[0]= 1721
freightId[1]= 1722
freightId[2]= 1723
....

Therefore assign your function results into another array . For ex:
fnc_results[0] = 500
fnc_results[1] = 550
fnc_results[2] = 560
....

Then make them come together like this ;

for(int i= 0 ; i< 10 ;i++ )
cout << "Frieght ID is: " freightId "costs :" + fnc_results

Good luck.

Well what i need is I need the result of Case 1 to be stored under one of the numbers in int FreightId. I would like it so that each time the program is used it will store the result under different values in FreightId. This is so that in Case 2 i can look up 1722 for example then my program will display the stored value.

#include <iostream>
#include <iomanip>
#include <ctime> 
#include <cstdlib>
using namespace std;

double shipcharge(double kg,int miles)
{
       
	double sc;
	int p1=(miles/500);
	if (miles%500>0)p1++;
	if(kg<=2)sc=1.1*p1;
	else if(kg<6)sc=2.2*p1;
	else if(kg<10)sc=3.7*p1;
	else if(kg<=20)sc=4.8*p1;
	return sc;
}

int main()
{
   int choice;       // Menu choice
   int freightId [] = { 1721, 1722, 1723, 1724, 1725, 1726, 1727, 1728, 1729, 1730, 1731, 1732, 1733, 1734, 1735, 1736, 1737, 1738, 1739, 1740, 1741, 1742, 1743, 1744, 1746, 1747, 1748, 1749, 1750, 1751, 1752, 1753,1754, 1755, 1756, 1757, 1758, 1759, 1760, 1761, 1762, 1763, 1764, 1765, 1766, 1767, 1768, 1769, 1770, 1771, 1772, 1773, 1774, 1775, 1776, 1777, 1778, 1779, 1780, 1781, 1782, 1783, 1784, 1785, 1786, 1787, 1788, 1789, 1790, 1791, 1792, 1793, 1794, 1795, 1796, 1797, 1798, 1799, 1800, 1801, 1802, 1803, 1804, 1805, 1806, 1807, 1808, 1809, 1810, 1811, 1812, 1813, 1814, 1815, 1816, 1817, 1818, 1819, 1820 };

Oh no it's not fair... Anyway, try this :

cout<<"Cost for "<<w<<" kg for "<<d<<" miles is $"<<fixed<<shipcharge(w,d)<<endl;
cout<< "Frieght ID is: "<< <<endl;

If freightId = 1721 assign i= 1721 then create a new array by using i,
freightId_cost = 50 $


cout<<"Updated cost for freightId "<<freightId []<<" is "<<w<<" kg for "<<d<<" miles is $"<<fixed<<shipcharge(w,d)<<endl;

If user inputs freightId [] = 1721 then freightId_cost will become freightId_cost [1721] which equals 50$
