Derived Data Type:
Array is derived data type to store large collection of data of only one data type.
int mark[100];
char names[25];
Function: will be discussed early. Pointer:
Pointer variable works similar to pointer in C. int a, *ptr;
ptr = &a;
C++ has added features called constant pointer and pointer to a constant. char* const ptr1 = "good"; It is constant pointer
int const *ptr = &a; It is pointer to a constant
