Pointers lay the foundation of C programming, offering direct memory access and manipulation capabilities that are both powerful and complex. As we delve deeper into pointers, we encounter double pointers, an extension of the basic pointer concept. Do
int *int_ptr ### int_ptr is a pointer to data of type integer char *ch_ptr ### ch_ptr is a pointer to data of type character double *db_ptr ### db_ptr is a pointer to data of type double Note: The size of any pointer in C is same as the size of an unsigned integer. ...
You ultimately want int *myArr in main to simulate an array of int, but in getInputArr you refer to it using a "double pointer" int **myArr. But this makes sense, because any time you want to return something from a function "by reference" like this, you need to ...
It's creating a size 0 bitfield if the condition is false, but a size -1 (-!!1) bitfield if the condition is true/non-zero. In the former case, there is no error and the struct is initialized with an int member. In the latter case, there is a compile error (and no such thi...
Array is a collection of variables belongings to the same data type. We can store group of data of same data type in an array. Pointer is a single variable that stores the address of other object/variable. Prev Next More C interview questions and answers: What is C lan...
std::auto_ptris the first smart pointer in C++. Its job is to take care of one resource. But it had a big issue. If you copy astd::auto_ptr,a move operation will occur under the hood. That is the reason we getstd::unique_ptrwith C++11 as the replacement. You can not copy ast...

What is a programming language? A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU (Central Processing Unit). The programming language mainly refers to high-level languages such as C, C++, Pascal, Ada, COBOL, etc. ...
Know what are data structures, types of data structures like primitive/non-primitive, static/dynamic, data structure array, stack, queue & much more in detail with examples.
For example, in a game you can use the mouse to point a gun in the direction to shoot. Open or execute a program - Once you've moved the pointer to an icon, folder, or another object clicking or double-clicking that object opens the document or executes the program. Some programs ...
