Pointer and non-pointer variables declarations together in C?

Learn: How to declare pointer and non-pointer variables together using single declaration statement in C/C++ programming language?

Let suppose, if you want to declare three variables in which two are pointers and one is not a pointer variable, we can declare them in a single line declaration statement.

Consider the following declaration:

int *ptr_a,*ptr_b,c;

Here,
ptr_a - is an integer pointer
ptr_b - is an integer pointer
c - is an integer pointer (a non-pointer variable)

Declaration of integer array and pointer to array together (using single declaration statement)

Consider the given declaration statement:

int arr[100], *ptr;

Here,
arr[100] - is an integer array with 100 elements ptr - is an integer pointer (pointer to an array)
