Requesting User To Input "Sum of two numbers"

Question

#include <iostream>
using namespace std;

int main()
{
int a, b;
int sum;
cout << "Enter a number \n";
cin >> a;
cout << "Enter another number \n";
cin >> b;
sum = a + b;
cout << "Sum is: " << sum <<endl;

return 0;

My question is why /n can not be replaced at <<endl Any help please. <<ednl and /n are same.

Answer 2

You can write like this:
cout << "Sum is: " << sum << "\n";

Answer 3

\n is used (as you did) in a string expression. like shamima did in his/her example too, within quotes. endl; is used out of string expressions (without quotes).
