Why Can't we copy a string to Character Pointer WHEN we can assign a string directly to it?

This code produces \"p = hello world\":

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

int main(){
    char *p;
    p=\"hello world\";
    printf(\"p is %s \\n\",p)

    There is no free lunch - you need to grab & manage memory. If you just assume that because you have access to a pointer memory should be there then you'll run into unspecified behavior (segfault likely).
