PLease I need help (knowledge of switches and functions)

[Richard Harris]

The message log keeps telling me that I am incorrectly using the switch statements. it says that I have incorrect breaks and cases. I don't' think so and so I don't know what to do. I cut my code up in order to see the jist of it. any help would be greatly appreciated! I should have gotten this by now.

  #include <iostream>
#include <stdio.h>
#include <ctype.h>
#include<time.h>
#include<math.h>

{	
	signed int  x,y;
	signed int  guess;
	signed int  pass;
	
	srand((unsigned)time(0));
	x=rand()%(10^(b-1));
		y= rand()%(10^(b-1));

	cout<< "--------Multiplication-------\n\n"<<endl;
	cout<<endl;
	cout<<endl;
	cout<< x <<" X "<< y<< " = \n    Enter Answer"<<endl; 
	cin>> guess;

	{	pass = 1;}
	while  (guess != (x*y))

	return (pass);

Let's take this one at a time.

main.cpp:34:21: warning: suggest parentheses around assignment used as truth value [-Wparentheses]
  while (guess = (x*y))
                     ^

You probably meant while (guess == (x*y)) here.

main.cpp: In function 'void Outstatment(int)':
main.cpp:109:4: error: case label not within a switch statement
    default: cout<< " what it this ?" <<endl;
    ^

The indentation here is really bad, so it's hard to see, but your default: case is outside of your switch statement.
You probably just misplaced/added an extra } or something.

main.cpp: In function 'int main()':
main.cpp:178:21: error: 'MathOp_A' was not declared in this scope
      MathOp_A (level);
                     ^
main.cpp:182:21: error: 'MathOp_B' was not declared in this scope
      MathOp_B (level);
                     ^
main.cpp:190:21: error: 'MathOp_D' was not declared in this scope
      MathOp_D (level);
                     ^

I suppose you probably have these functions defined in your code, but you deleted them in order to save space when you posted it.

main.cpp:208:5: error: expected ';' before 'Outstatment'
     Outstatment(op);
     ^

You missed a semicolon at the end of your while (level != 0) (line 198).

main.cpp:231:1: error: case label ''n'' not within a switch statement
 case 'n': 
 ^
main.cpp:235:2: error: case label not within a switch statement
  default:  cout<< "okay bye."<<endl;
  ^
main.cpp:238:5: error: case label not within a switch statement
     default:   cout<<"hahha"<<endl;
     ^

Once again, these case values are outside of your switch.
In this case, the first default: case is actually inside your case 'n': block!

main.cpp:240:3: error: expected 'while' before '}' token
   }while (play!=0)
   ^
main.cpp:240:3: error: expected '(' before '}' token
main.cpp:240:3: error: expected primary-expression before '}' token
main.cpp:240:3: error: expected ')' before '}' token
main.cpp:240:3: error: expected ';' before '}' token
main.cpp:123:14: warning: unused variable 'a' [-Wunused-variable]
  signed int  a;
              ^
main.cpp: At global scope:
main.cpp:240:4: error: expected unqualified-id before 'while'
   }while (play!=0)
    ^
main.cpp:242:5: error: expected unqualified-id before 'return'
     return 0;
     ^
main.cpp:243:1: error: expected declaration before '}' token
 }
 ^

You put one too many closing braces (}) at the end, so this part:

}while (play!=0)
    system("pause");
    return 0;
}

is actually outside of main (that first closing brace there on line 240 ends the main function).

Again, some indentation would make these errors much clearer.
