What is the difference between char array[50] and char *array = new char[50]? [duplicate]

1. char array[50] is 50*sizeOfChar space allocated on stack. char *array = new char[50] is 50 * sizeOfChar space allocated on heap, and address of first char is returned.
2. Memory allocated on stack gets free automatically when scope of variables ends. Memory allocated using new operator will not free automatically, delete will be needed to be called by developer.

Mixing C/C++ is a nice though sometimes confusing:

char array[50];

Allocation on stack, so you don't need to worry about memory management. Of course you can use std::array<char, 50> array which being C++ brings some advantages (like a method which returns its size). The array exists until you leave its scope.

char *array = new char[50];

Here you need to manage the memory, because it is kept in the heap until you free it. Important, you should use this whenever you want to remove it:

delete [] array;

There also exist free(array) (Standard C) and delete (without parenthesis). Never use those, whenever you use new someType[...].

Other that in both you still have a char array of 50 elements you can play with :-)
