Not only str="abcdefg" is legal and working, but your replacement has
several errors in it.

Please learn the difference between a character literal and a string
literal; and then learn about initializing all your variables; then learn
about the use of memory allocation and deallocation; then learn how you
can fix your code; then learn why the original code can be right too.

That's it, nothing important, but may be worth learning for your next
post about C code.
