Pointer Hackerrank Solution in C++

Task: A pointer in c++ is used to share a memory address among different contexts (primarily functions). they are used whenever a function needs to modify the content of a variable, but it does not have ownership. in order to access the memory address of a variable,, prepend it with a sign. for example, &val returns the memory address of. this memory address is assigned to a pointer and can be shared among functions. for example, assigns the memory address to the pointer. 

To access the content of the memory pointed to, prepend the variable name with a *. for example, *p will return the value stored in and any modification to it will be performed. void increment(int *v) { (*v)++; } int main() { int a; scanf("%d", &a); increment(&a); printf("%d", a); return 0; } function description complete the update function in the editor below. update has the following parameters: int *a: an integer int *b: 

An integer returns the function is declared with a void return type, so there is no value to return. modify the values in memory so that contain their sum and contains their absolute difference. input format input will contain two integers, and, be separated by a new line. sample input 4 5 sample output 9 1 explanation

We know about the pointer, as we know the pointer holds the address of another variable. In this problem, we are passing the address of a variable not the value of the variable so anything that changes in the value, affects the original value of the variable. If you want to practise in pinter there are many programs you can understand.

#
include <iostream>
using namespace std; void update(int *a, int *b) { int temp = *a; *a = *a + *b; *b = temp - *b; if (*b < 0) { *b = -(*b); } } int main() { int a, b; int *pa = &a, *pb = &b; cin >> a >> b; update(pa, pb); cout << a << "\n" << b; return 0; }
