C++ StructureArray is a collection of variables of same data types as to store roll numbers of 10 students, better to use array of size 10 instead of using 10 variables. Suppose we have to store details of 10 student as student name, roll number and cgpa where data type of each is different. For this we use structure. So we can say that..Structure in C/C++ is a collection of variables of same or different data types under a single nameStructure declaration in C/C++Structure can be declared either inside main function or before main function. Syntax of struct declaration is as belowstruct structure-name{ data members
};Below is the code for declaring a structure named Student. structStudent{ string name; int rollNo; float cgpa; }; Student structure contains three variables i.e name, rollNo and cpga.

Array in c programming

Why we need array in C++Suppose you have to calculate average of four numbers. What will you do? You will declare four int variables to store four numbers, then will add all numbers and divide by four. You will get average. Code is given blow.
int num1 =9; int num2 =8; int num3 =7; int num4 =6; int sum=num1+num2+num3+num4; int average = sum /4;
Now consider a scenario where you need to calculate average of 100 numbers. Will you declare 100 variables of int data type? Obviously it is not convenient to declare 100 variables. Here C++ array helps to overcome this problem. What is Array in C/C++ Array in C programming is a container to store multiple values of same data type. Rather then declaring 100 variables to store 100 numbers, one int array of size 100 will be used. How to declare Array Syntax of array declaration is below Data-type array-name[size of array];
int numbers[100];
This array declaration is equivalent to declaring 100 int variables. How to initialize array / insert element in ar…

Pointer to pointer

What is Pointer to pointer Till now, we were doing single dereference. It means that there is pointer which contain memory address of a variable.
Pointer to pointer is a new concept in which we will do double dereferencing. It means that one pointer contain memory address of another pointer or array of pointers in c. Pointer to pointer in c is declared as
int**pptr; How to initialize a pointer to pointer c++Pointer to pointer always store memory address of another pointer (Not Variable) as below code will generate error
int x =10; int**pptr=&x; //Error
We can use pointer to pointer as
int x =10; int*ptr =&x; int**pptr =&ptr;
In above code, using reference operator (&) memory address of variable x is assigned to a pointer ptr. It is important to understand that like variable, when we declare a pointer, it also reserve memory equal to size of 4 bytes regardless of its data type. In last line, we are assigning memory address of ptr to pptr. Using dereferencing, we can get value…
