5.1 Introduction

5.1 Introduction

5.1 Introduction. Pointers Powerful, but difficult to master Simulate pass-by-reference Close relationship with arrays and strings. POINTERS & ADDRESSES. C++ allows a programmer to access the address of variables. And addresses can be added, subtracted and compared.

Remark: Data Type of Array Name

Remark: Data Type of Array Name

Remark: Data Type of Array Name. Example: int arr[10] Array name arr is a pointer The pointee of arr is arr[0], which is an integer So the data type of arr is int * In general, for an array of data type T, i.e. T arr[arraysize] the array name is a pointer variable of type T *.
