a calculator using altera monitor program

[Altera_Forum]

I am working on altera De2-70 board, using altera monitor program. i am continuously getting errors for syntax in c on altera monitor program. does it use different syntax or just same as c programming? 

           /* //the worked simple blink code   # define switches (volatile char *) 0x0002000   # define leds (char *) 0x0002010   void main(){   while (1)   *leds = *switches;  }*/

"00111000" is a octal number 

"111000" would be decimal "0b00111000" would be binary  To get "A" use: A = (*switches>>0) & 0x07; B= (*switches>> 3) & 0x7; op = (*switches >> 6) & 0x3;
