Casting int pointer to char pointer causes loss of data in C?

Question

I have the following piece of code:

#include 
#include 
int main(int argc, char *argv[])
{
  int n = 260; 
  int *p = &n;
         


        

Answer 1

Your problem is the assignment *pp = 0; You're dereferencing pp which points to n, and changing n. However, pp is a char pointer so it doesn't change all of n which is an int. This causes the binary complications in the other answers.
