Can someone please help me with my errors?

Here is my code:

Code:

//name
//CSCI 1010 Section 3
//Assignment 4
//9.28.06
//The purpose of this program is to price an entered number of shirts.  More shirts means less cost per shirt.

#include<iostream>
using namespace std;

int main ()
{
        int shirts, price;
        cout << "Welcome to Expensive Shirts Dot Com!" << endl;
        cout << "Enter the number of shirts you wish to purchase:" << endl;
        cin >> shirts;
        if (shirts < 0)
        {
                cout << "ERROR: You must enter a positive number. We only sell shirts. We do not buy them." << endl;
        else if (shirts < 3)
                {
                price = shirts * 12;
                cout << "Total cost of " << shirts << " shirts: $" << price << endl;
                }
        else if (shirts < 10)
                {
                price = shirts * 10;
                cout << "Total cost of " << shirts << " shirts: $" << price << endl;
                }
        else if (shirts < 24)
                {
                price = shirts * 8;
                cout << "Total cost of " << shirts << " shirts: $" << price << endl;
                }
        else if (shirts > 24)
                cout << "Sorry, you cannot order more than 24 shirts." << endl;
        }
return 0;
}

Here is the error message when i tried to compile:

Code:

                                                                                                                              
a4xxxxxxxl.cpp: In function `int main()':
a4xxxxxxx.cpp:19: syntax error before `else'
a4xxxxxxx.cpp: At global scope:
a4xxxxxxx.cpp:37: syntax error before `return'

you don't have the opening curly bracket after the last else if (shirts > 24)

didnt work. i didnt think i needed one since it has only one line in it. the ; closes it

last else doenst need if, ill try that

fixed one error by taking if out of the last else.

new error message:

Code:

a4xxxxxxx.cpp: In function `int main()':
a4xxxxxxx.cpp:19: syntax error before `else'
a4xxxxxxx.cpp:35: syntax error before `<<' token

When you have a series of if, else if statements, you don't enclose all the else ifs inside the if braces. Instead of this:

Code:

if ()
{
    else if
    {
    }
    else if
    {
    }
}

you should be doing this:

Code:

if ()
{
}
else if
{
}
else if
{
}

k, did that, it is still giving errors:

Code:

a4xxxxxxx.cpp: In function `int main()':
a4xxxxxxx.cpp:35: syntax error before `<<' token

Did you change it to:

Code:

else(shirts > 24)
     cout << "Sorry, you cannot order more than 24 shirts." << endl;

This would cause an error, because else cannot have any "parameters".

If you have else put correctly, then you should try adding braces to that else, because C++ is a free-form language and this would look suspicious:

Code:

else cout << "Sorry, you cannot order more than 24 shirts." << endl;

thanks much.

Which one was the error?
