In this program, the elements are stored in the integer array data[]. Then, the elements of the array are accessed using the pointer notation. By the way, data[0] is equivalent to *data and &data[0] is equivalent to data data[1] is equivalent to *(data + 1) and &data[1] is ...
C program, using pointer for string comparison
Since, we cannot change the value of a constant but using pointer we can change it, in this program we are doing the same. Here, we have an integer constant and changing its value using pointer. Example /*C program to change the value of constant integer using pointers.*/#incl...
Here the pointer variable is allowed to point to any data type, and this type is used in passing pointers to functions that work independently of the data type that is pointed to. Syntax: void * pointer variable; Example: Code: #include<iostream.h> #include <iostream> using namespace std...
By default, after everycallcommand,dbxautomatically callsfflush(stdout)to ensure that any information stored in the I/O buffer is printed. To turn off automatic flushing, set thedbxenvironment variableoutput_auto_flushtooff. For C++,dbxhandles the implicitthispointer, default arguments, and function...
When you are stopped in a member function, you canlook up thethispointer. (dbx)stop in brick::draw(dbx)cont(dbx)where 1brick::draw(this = 0x48870, pw = 374752), line 124 in "block_draw.cc" (dbx)whatis thisclass brick *this; ...

Write a C program to copy an array into another and then reverse the new array before printing. Write a C program to copy only the even elements of an array into a new array. Write a C program to copy an array using pointer arithmetic and then verify both arrays are identical element-...
Question:What is a Pointer? What are its limitations? What are its benefits? How do we use it? What all operation we can perform using it? In this article we are going to discover answers to all these questions. 指针是一个包含其它变量地址的变量,这里的其它变量可以是结构,数组或则其它基本类...
实际上,vbptr 指的是虚基类表指针(virtual base table pointer),该指针指向了一个虚基类表(virtual table),虚表中记录了虚基类与本类的偏移地址;通过偏移地址,这样就找到了虚基类成员,而虚继承也不用像普通多继承那样维持着公共基类(虚基类)的两份同样的拷贝,节省了存储空间。
