Answer 1

Incompatible types.

To begin with, human.nickname[20] is the 21st character in a character array. You cannot put a const string into a char spot.

If you remove the array indexing operation, human.nickname = "BABU", then you are assigning to an array. The declaration

public :
char nickname[20] ;

reserves 20 chars inside the memory area of the object for a string. "BABU" is a string in the read only data section of your program. You cannot copy on assign in C++. You have to manually copy char for char into the object.

Alternatively, you make nickname point to a const char instead

public :
const char *nickname;

But best would be to use a string datatype, instead of dealing with C strings.
