pointers can also be declared as void type.void pointers cant be dereferenced without explict type conversion,this is becoz being void the compiler cnt determine the size of object that pointer points to,though void vaariables declared is not allowed,thus void p displays error msg "size of p is unknown or 0" after compilation
#include<stdio.h>
int p;
float d;
char c;
void *pt=&p;
void main(void)
{
clrscr();
*(int*)pt=12;
printf("\n p=%d",p);
pt=&d; /*pt points to d*/
*(float*)pt=5.4;
printf("\n r=%f",d);
pt=&c; /*pt points to c*/
*(char*)pt=H;
printf("\n c=%c",c);


o/p:
P=12
R=5.4
C=H

int main() { Int n=20,i; For(i=0;i<=n;i--) { Printf(“-“); Return 0;
