I am not only new here, but, I am a complete newbie to programing. I was on the hunt for some beginner tutorials today on the web. I found what I thought would be a simple yet in depth problem. I spent the last hour making sure that I had typed everything exactly as instructed (you tube video) and when I tried to compile, MSVC++EXS came back with about twenty errors. Now I saw the code run on the video, so I feel confident that it should work. But no dice here. I will post both a link to the original and the code as follows:
// This is a program about loops, switch statements, ifelse statements
//and applying them to another faily simple programme.
#include <iostream>;
using namespace std;
int main ()
{
system ("TITLE Calculator");
system ("COLOR 2");
char cChar;
double dfirstnumber;
double dsecondnumber;
char cDoagain;
do
{
system ("CLS");
cout<< "Please enter the first number that you would like to use." << endl;
cin>> dfistnubmer;
cout<< "Please enter the operation that you would like to complete."
<<" (+,-,* and /)"<< endl;
cin>> cChar;
cin<< ("Please enter the second number that you would like to use.") << endl;
switch (cChar);
{
case "+";
cout<< " The Answer is:"<< dfirstnumber << "+" << dsecondnumber
<< dfirstnumber << "=" << dfirstnumber + dsecondnumber
<< endl;
case "-";
cout<< " The Answer is:"<< dfirstnumber << "-" << dsecondnumber
<< dfirstnumber << "=" << dfirstnumber - dsecondnumber
<< endl;
break;
case "*";
cout<< " The Answer is:"<< dfirstnumber << "*" << dsecondnumber
<< dfirstnumber << "=" << dfirstnumber * dsecondnumber
<< endl;
break;
case "x";
cout<< " The Answer is:"<< dfirstnumber << "x" << dsecondnumber
<< dfirstnumber << "=" << dfirstnumber * dsecondnumber
<< endl;
break;
case "X";
cout<< " The Answer is:"<< dfirstnumber << "X" << dsecondnumber
<< dfirstnumber << "=" << dfirstnumber * dsecondnumber
<< endl;
break;
case "/";
if (dsecondnumber == 0) {
cout << " That is an invalid operation!" << endl;
}else {
cout<< " The Answer is:"<< dfirstnumber << "/" << dsecondnumber
<< dfirstnumber << "=" << dfirstnumber / dsecondnumber
<< endl;
}
break;
default:
cout<< " That is an invalid operation" << endl;
break;
{
cout<< " Would you like to start again? (Y or N)" << endl;
cin>> cDoagain;
}while (cDoagain == 'Y' || cDoagain == 'y');
system ("Pause");
return 0;
}
Also I thought that I would include the error log so that some one might possible explain what it is that the program is talking about and possible way to fix them. Error Log

If you all could assist me in find out how to fix the errors I would greatly appreciate the assistance.

In addition to the above posts:
1) The user has no chance to input the second number. Better add cin>>dsecondnumber; after the user is told to input the second number.
2) In your case statements the output is always
Exactly what I was going to say, unbeatable0. You are far better off learning from some sort of print media than video.
To be completely honest, if you're truly committed to learning how to program, investing in a good solid C++ book shouldn't be out of the question. The lessons will be written down, you can notate a book, there will be practice questions with answers, and the lessons will be complete.
When I was learning Ogre3D, I tried to do it from online tutorials, but in the end, learned there is no substitute for a well written book.
For all of the people saying that I should get a good text, I am in concurrence with you on that statement. I have to get some cash together so that I can invest. The on line tutorials are a supplement to the texts that I am planning to purchase in the future. Thank you all for you assistance, I really appreciate all of your guidance.
