Either but a book on C or C++, if you can.
Or search www.google.com.
Or try here
http://msdn.microsoft.com/library/devprods/vs6/visualc/vclang/_clang_the_c_s
witch_statement.htm

I know is MS but it's all the same. It was just the first site I can across
using goggle the described the C switch statement.

Regards,

James.

You have if(type = 'Q'); <--- remove the ; as you have an empty control
statement.

Your missing a return before the closing } in main.
Basically if your program doesn't run into any of the if tests then it falls
out of the bottom without returning a value. (add return 0; before the last
})

A suggestion would be to replace the if's with switch statements.

i.e.

switch(type)
{
 case 'Q':
  ...
  break;
 case 'C':
  ...
  break;
}

Regards,

James.

I'm trying to add another feature to my primitive program :O) I was trying
to add a regular calculator allowing a choice from the quadratic equation
calculator and from a regular arithmetic calculator I keep getting two
errors which I marked in the code below I'm still a beginner so I as if what
I'm trying to do even possible if not can I have a program open either one
(each in its own executable) if so how? Thanks

Error summary

1.       Parse error before 'else' line 69
