Indefinite loop in C Program

Program #16

Description:
To iterate indefinite loop until user press any keyboard characters.

void main(){
clrscr();
 /*
 Indefinite loop using kbhit() function
 kb  - KeyBoard
 hit - Type/Enter
 */
 for(;!kbhit();){
    printf(" * \t @ \t & \t %");
 }
 getch();
}

Note:
kbhit() functionality will not obey for few keyboard characters.. I am expecting the answer from blog readers.  Once you know the key.. Reply it.!!
