Hi all.
I have found some tutorials online, I believe they were from some university classes, and one from a guy named Juan Soulie.

I seem to have solved the bulk of my issues, yet have one last one-- that I can identify.

For some reason that I still don't understand, I keep getting a c2059 error, stating that return is a syntax error.

int main(void)
{
	do 
	{
cout << "         Copyright 2001, Welcome to the Angle Finder Program.          " << endl;
cout << "        This program is designed to take only numeric values.          " << endl;
cout << "       Make certain you only input numbers. Otherwise it will exit.    " << endl;
	cout << " Please choose:  1 for the Hip/Valley Angle. "         << endl;
	       cout << "                 2 for the Cricket Valley Angle. "     << endl;
	       cout << "                 3 for the Ridge Angle "               << endl;
	       cout << "                 0 to exit. "                        << endl;
		char ch;
		cin >> ch;
		
switch (ch)
{ 
     case '1' :  int HipValley(int& Rise1, int& Rise2, double& Eave, float& a); 
                    // this is the Hip/Valley choice.
	break;

     case '2' : int CricketValley(int& Rise1, int& Rise2, double& Eave, float& a, float& Width); 
                   // this is the cricket valley choice.
	break;

      case '3' : int RidgeAngle(int& Rise1, int& Rise2); // this is the Ridge Angle choice.
               break;
      default : return 0; // this will end the routine.
 }  while (ch != 27);
        }
return 0; //line 186

}

This is the error:

e:\..folder path.....\steveangle.cpp(186) : error C2059: syntax

I've checked my '{' braces, and everything else seems to work, but it keeps calling this error.

I think it was your do-while loop. Maybe the program misinterpreted the return 0 and was looking for a while loop. Consider your code--

int main(void)
{
	do 
	{
		cout << "         Copyright 2001, Welcome to the Angle Finder Program.          " << endl;
		cout << "        This program is designed to take only numeric values.          " << endl;
		cout << "       Make certain you only input numbers. Otherwise it will exit.    " << endl;
		cout << " Please choose:  1 for the Hip/Valley Angle. "         << endl;
		cout << "                 2 for the Cricket Valley Angle. "     << endl;
		cout << "                 3 for the Ridge Angle "               << endl;
		cout << "                 0 to exit. "                        << endl;
		char ch;
		cin >> ch;

		switch (ch)
		{ 
			case '1' :      
					int HipValley(int& Rise1, int& Rise2, double& Eave, float& a); 
					// this is the Hip/Valley choice.
				break;

			case '2' :      
					int CricketValley(int& Rise1, int& Rise2, double& Eave, float& a, float& Width); 
					// this is the cricket valley choice.
				break;

			case '3' : 	
					int RidgeAngle(int& Rise1, int& Rise2); // this is the Ridge Angle choice.
				break;
				
			default : 
				return 0; // this will end the routine.
				
		} while (ch != 27); //while loops after switch statement
	} //no while loop here, where program expects it
	
	return 0; //line 186
}

Try this --

int main(void)
{
	do 
	{
		cout << "         Copyright 2001, Welcome to the Angle Finder Program.          " << endl;
		cout << "        This program is designed to take only numeric values.          " << endl;
		cout << "       Make certain you only input numbers. Otherwise it will exit.    " << endl;
		cout << " Please choose:  1 for the Hip/Valley Angle. "         << endl;
		cout << "                 2 for the Cricket Valley Angle. "     << endl;
		cout << "                 3 for the Ridge Angle "               << endl;
		cout << "                 0 to exit. "                        << endl;
		char ch;
		cin >> ch;

		switch (ch)
		{ 
			case '1' :      
					int HipValley(int& Rise1, int& Rise2, double& Eave, float& a); 
					// this is the Hip/Valley choice.
				break;

			case '2' :      
					int CricketValley(int& Rise1, int& Rise2, double& Eave, float& a, float& Width); 
					// this is the cricket valley choice.
				break;

			case '3' : 	
					int RidgeAngle(int& Rise1, int& Rise2); // this is the Ridge Angle choice.
				break;
				
			default : 
				return 0; // this will end the routine.
				
		} 
	}while (ch != 27); //now should be a functional do-while loop
	
	return 0; //line 186
}

Well because your indentation sucks, it's impossible for you to tell that the
while (ch != 27);
is stuck on the closing brace of the switch, and not the closing brace of the do

Salem,
Thanks.
I don't know why my indentation got so screwed up.
It looked fine when I posted.
After I posted, I dug more, and realized that it was the placement of my while statement. I'd had it one brace too deep.
This portion is now resolved.
Thanks for your posts.
