Pointer in C++: A pointer is a variable whose value will be another variable’s address. Generally, a pointer variable is declared as follows: type var-name; Here, type is the pointer’s base type and var-name is the pointer variable name. The asterisk is used to designate a variable as a pointer. Given Program: //Include libraries #include <iostream> //Use namespace using namespace std; //Define main method int main() { // Declare pointer variables int p1, p2; //Assign value p1 = new int; //Assign value p2 = new int; //Assign value p1 = 10; //Assign value p2 = 20; //Display value cout << p1 << " " << p2 << endl; //Assign value p1 = p2; //Display value cout << p1 << " " << p2 << endl; //Assign value p1 = 30; //Display value cout << p1 << " " << p2 << endl; //Pause console window system("pause"); //Return 0 value return 0; }

Students have asked these similar questions

what will be the output? #include int main () {int i = 3; i++; print ("%d", i); i--; print ("%d", i); return 0;} a. 34, b. 33, c. 44, d. 43

In Java: Develop a void function that takes two integers and prints whether the first number is divisible by the second. For example, with arguments 51 and 17, the function should print “51 is divisible by 17”. With arguments 17 and 8, the function should print “17 is not divisible by 8”. Call the function twice with different arguments to show each possible result. What happens when the second argument is greater than the first?

what will be the output? #include int main() {int i = 3; i++; printf ("%d", i); i--, printf("%d", i); return 0;}
