C) The string object is assigned a value correctly, but the C-string is not.
D) The C-string is assigned a value correctly, but the string object is not.
E) All 4 lines of codes are correct.

Answer 1

The answer to this question is option (C).C-String is not assigned value correctly.

Step-by-step explanation:

This is because the size with which c-string is initialized is 7 and we are providing a string of 7 characters to store So there is no space left to store the null character '\0' .We can only store a string of size 6 in the c string.There is no need to provide the size in the string object as it is handled by string class.
