So, here is the updated thread: Maybe there is white space in there that I'm not seeing? It is the exact same error as it was before. You anyone can think of anything to try, ill do it.
#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;
int main()
{
// 1. Initialize Objects
double retail = 0.0;
double markup = 0.0;
double wholesale = 0.00;
// 2. Input
cout << "Hello Emily CO 127: ";
cout << "Enter Retail Price: ";
cin >> retail;
cout << "Enter Mark Up Percent: ";
cin >> markup;
// 3. Process
wholesale = retail * (1 + markup);
cout << " Wholesale " << wholesale << endl;
return 0;
system("pause");
}

Answer 1

using namespace std; is a declaration that introduces the identifiers from the namespace called std in the global scope. It is not the beginning of function or starting point for a block. What you're missing is your main function:
int main() // start of the program
{
// ...
}
This is what your program should look like then:
#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;
int main()
{
// 1. Initialize Objects
double retail = 0.0;
double markup = 0.0;
double wholesale = 0.00;
// 2. Input
cout << "Hello Emily CO 127: ";
cout << "Enter Retail Price: ";
cin >> retail;
cout << "Enter Mark Up Percent: ";
cin >> markup;
// 3. Process
wholesale = retail * (1 + markup);
cout << " Wholesale " << wholesale << endl;
return 0;
system("pause");
}
You should read up more on the basics of C++, they will explain everything you need to know.
