    If you allocate memory with new , then you need to store pointers in the class, not arrays. - HolyBlackCat

Well, you can not assign something to an array in C / C ++. How do you even imagine it?

 char name[25]; name = new char[50];

name is a declared array, which is always that array. Very roughly - as the number 2 is the number itself, and assign 2 = 5; is impossible.

Work with pointers -

 char * name;
