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

In your code:

char *p="abc";

p points to a string literal - you are not allowed to change string literals, which is what your call to strcpy is trying to do. Instead, make p an array:

char p[] = "abc";

which will copy the literal into something that you are allowed to modify.
