trovare 3 b consecutive errore ; expected before string riga 18 19

[8claudio8]

#include <stdio.h>

#include <conio.h>

int main() {

char a[]="abbbaaaaaa";
int trovato=0,i=0,x=0,y=0;

do{

x=i+1;y=i+2;
if((a[i]=='b')&&(a[x]=='b')&&(a[y]=='b')){trovato=1;}
else{i++;};
}
while((trovato!=1)||(i>=10));

if(trovato==1){printf"vero";}
else{printf"falso";}
getch();
return(0);

}

Mi dà errore riga 18 19 ; expected before string

Perchè?
