selection structure problem

[zelmila19]

Hi
I have to create a program that displays a shipping charge. The shipping charge is based on the state name entered by the user, as shown:
State

Shipping charge ($)

Alabama

25

Alaska

50

If the user enters any other state name, the shipping charge should be 0 (zero).
So far I've come up with this but am having errors. Can someone help check my code out?

#include <iostream>
#include <string>
#include <algorithm>

using std::cout;
using std::cin;
using std::endl;
using std::string;

int main()
{
//declare variables
string state = "";
int shipCharge = 0;
const int Alabama = 25;
const int Alaska = 20;

//enter input item
cout << "Enter the state name: ";
cin >> state;
getline(cin, state);

//assign shipping charge
if (state = "Alabama")
{
cout << shipCharge << "Alabama" << endl;
}
else if (state = "Alaska")
{
cout << shipCharge << Alaska << endl;
} //end if

//display shipping charge
cout << "Shipping charge: " << shipCharge << endl;

return 0;
} //end of main function

Can you write those errors here?

This is the error am getting:

This is your problem:

[CODE=cpp]if (state = "Alabama")
{
cout << shipCharge << "Alabama" << endl;
}
else if (state = "Alaska")
{
cout << shipCharge << Alaska << endl;[/CODE]

You are assigning "Alabama" to state instead of testing whether state equals Alabama.Change assigment operator(=) with equality(==) and it should be fine.

Thank you, now it doesnt have errors but it's not giving the value :(

Thank you, now it doesnt have errors but it's not giving the value :(

That's because of this:

[CODE=cpp]cin >> state;
getline(cin, state);[/CODE]

Any reason why are you inputing state twice?
