Thread: What the heck? Why am I getting 2 errors?

I tryed and tryed to see what is wrong with this code, and it just doesn't seem to want to compile. I get these 2 errors:

line 124 c:\dev-c_~1\mathfun.cpp parse error before `else'
line 142 c:\dev-c_~1\mathfun.cpp parse error at end of input

I was making this program for my little brother to help him with his times tables.

Here it is:

Code:

#include <iostream.h>
#include <stdlib.h>
#include <time.h>
#define MAX_RANGE 20

int main()
{
 int answer;
 int input;
 int valuex;
 int valuey;
 int points;
 int chance = 0;

 start: // the beginnning labeled for a goto statement

 for(int i = 0; i = 100; i++)
 {
  points++;
  srand ( time (NULL) );         // Initialize random generator
  valuex = rand()%MAX_RANGE+1;    // Get random between 1 and MAX_RANGE

  srand ( time (NULL) );         // Initialize random generator
  valuey = rand()%MAX_RANGE+1;    // Get random between 1 and MAX_RANGE

  answer = valuex * valuey;
  cout<<"What is"
      <<valuex<<" x "
      <<valuey<<"?";

  cin>>input;

  if(input != answer)
  {
   chance++;
   cout<<"\n Sorry! That is wrong!\n"
       <<valuex<<" x "<<valuey<<" =\n"
       <<answer<<endl;

       if(chance = 1)
       {

        cout<<"\n You have one more chance!\n"
            <<"Press any key to continue. . .";
        system("PAUSE > nul");

       }

       else if(chance = 2)
       {

        cout<<"\n This is your last chance... \n"
            <<"Press any key to continue. . .";
        system("PAUSE > nul");

       }

       else

       {
        system("CLS");
        cout<<"GAME OVER!\n"
            <<" You scored a total of "
            <<points<<"points!";

            if(points < 25)
            {

             cout<<"\n\n You are classed as a little kid.\n"
                 <<"Press any key to exit the game. . .\n";

             system("PAUSE > nul");
             return 0;

            }

            else if(points >= 25 &&(points < 50))
            {

             cout<<"\n\n You are classed as a 4th grader.\n"
                 <<"Press any key to exit the game. . .\n";

             system("PAUSE > nul");
             return 0;

            }

            else if(points >= 50 &&(points < 75))
            {

             cout<<"\n\n You are classed as an average person.\n"
                 <<"Press any key to exit the game. . .\n";

             system("PAUSE > nul");
             return 0;

            }

            else if(points >= 75 &&(points < 100))
            {

             cout<<"\n\n You are classed as a smarty pants.\n"
                 <<"Press any key to exit the game. . .\n";

             system("PAUSE > nul");
             return 0;

            }

            else

            {

             cout<<"\n\nWow! You only missed 2!  Good job!\n\n"
                 <<"Press any key to exit the game. . .\n";

             system("PAUSE > nul");
             return 0;

            }

  } // end big if statement

  else
   cout<<"\nCorrect!\n\n";


 }//end for loop

 system("CLS");
 cout<<"What the world?\n"
     <<"Thats impossible!\n"
     <<"How did you beat me?\n"
     <<"\n\n You scored a total of "
     <<points<<" points!\n"
     <<"Thats amazing!!\n"
     <<"Press any key to start the game over. . .";
 system("PAUSE > nul");
 goto start;
 return 0;
}

I made it as neat as I could for its readablity.
I think it has to do with the nested if statements within the for loop or something. Did you find any errors? If you did what was the error, and how do I fix it for my future programs?

Thank-you so much,
Best Regards,

[You also have three other comparison problems

Code:

for(int i = 0; i = 100; i++)
...
if(chance = 1)
...
else if(chance = 2)

To test for equivalence you use ==. One = means to make an assignment. [/B]

if you get use to writing constance first then these errors will be flaged by the compiler.

if(chance = 1) // error but the compiler will not see it
if( 1 = chance) // error

Thanx guys! I appreciate your fast reply, and your dedication. Thank-you for the tip, and the fixed error.

About your headers:

<iostream.h> is no longer standard, <iostream> is. All the symbols in that header are in the std namespace, so putting a 'using namespace std;' declaration right below your includes will let you access them as you currently do.

The other two <stdlib.h> and <time.h> are still part of the C++ Standard Library (as they are part of the C Standard Library), but C++ also offers them as: <cstdlib> and <ctime> with the std namespace.
