Unreasonable Error

[Zach]

Im not sure why it comes up with these errors...they dont seem reasonable for me. I am new so I may of skipped something. Can some one tell em why im getting these codes and maybe post a correct code and/or an explination of why it gives me these?

Build Error output:

My code:

#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
int op;
cout << "Welcome to Zach's Calcualtor! Customly Built by Zach! Hand Written!\n\n";
cout << "This calulator can manage a few things:\nMulitiplication, Division (With remanders), Addition, and Subtraction\n\n";
cout << "You MUST restart the calcualtor to preform a diffrent operation\n";
cout << "What operation would you like to do?\n\n";
cout << "1=Division 2=Mulitplication 3=Addition 4=Subtraction\n";
cin >> op;
if (op=<2); // Division and Multiplication
{
}
else //Sub and Add
{
}

}

The Syntax error with the < has been resolved, All I need help with is the "illegal else without matching if" Error

[Disch]

an if block goes until the next pair of braces {} or until the next semicolon ;

because you have a semicolon immediately after the if, the if block is completely empty, followed by a pair of braces:

if(foo)
  ;   // the if block ends here
{
  // this is unrelated to the if.  It will run regardless of 'foo'
}
else  // error because it didn't immediately follow an if block 

in short: remove that semicolon:

if(foo)  // no semicolon here
{
  // now this is the if block
}
else  // now this works

also you should add a return statement at the end of the function:
return 0;

Well I acculay solved the problem strangely enough, without help. It turns out without ethir of the solutions given. I did it by pressing enter after "else" and nothing else. I didnt have a chance to post it though.

[Disch]

gah?

putting a new line after the else won't do anything. The only way to solve it is to do what I suggested and remove that semicolon.
