How can a char pointer be initialized with a string (Array of characters) but an int pointer not with an array of integer?

How can char pointer be initialized with a string (Array of characters) but an int pointer not with a array of integer?

When I tried this

int* a={1,2,3,4,5};

It gives an error saying

error: scalar object ‘a’ requires one element in initializer

But,

char* name="mikhil"

works perfectly.
