{geshibot language="c"}#include #include int main() { int a=10; void *p; p=&a; clrscr(); printf("%u",*p); getch(); return; }{/geshibot} I know that this program is wrong as error is shown on compiling it. Anyone please provide a simple program using Void pointer in C. Thanks in advance :)

You have to typecast void pointer to int as *(int*)p;

Code
#include<stdio.h>
#include<conio.h>
int main()
{
 int a=10;
 void *p;
 p=&a;
 clrscr();
 printf("%u",*(int*)p);
 getch();
 return 0;
}

Your error is on line 9, where youve attempted to dereference a pointer to void (the expression *p). You can only dereference typed pointers. The solution you are probably looking for would be to repl...

The fastest way to do this is to traverse the linked list forward once, saving the value at each node (or a pointer to the node) in a backwards-traversable data structure. If you know the size of the ...

This seems to be a question about time complexity / big-O notation. Time complexity basically tells you how the program running time scales, as a function of one of the variables of input (in most cas...

Start at floor 10. If the marble breaks start at 1. If it Doesnt go to 20: repeat for 11-19, and Repeat the process for 30,40,... to 100. Max amount of Drops will be 19: at 91. Up all the way to 100(10 drops) and 9 floors down(9 drops)

With 2 marbles: Go to floor 50. If the marble breaks, go to floor 1 then floor 2 and so on up to floor 49 or until your marble breaks. Then the solution is the previous floor. If the marble doe...

Some kind of information regarding the type is obviously required. If there is no way of determining it from the context (i.e., the previous node in the list somehow specifies the type), it must be st...
