Why can't I use this code to overwrite a string?

Question

Code:

#include \"stdio.h\"
#include \"string.h\"

int main()
{
  char *p = \"abc\";
  printf(\"p is %s \\n\", p);
  return 0;
}

Answer 1

p is basically just a pointer to read-only data (which is "abc" in your case). You cannot overwrite that with "def".
