How can we give space between two line statement?

Question

Hello world
welcome to coding

Answer 1

cout << "Hello world\nwelcome to coding";

or

cout << "Hello world" << endl;
cout << "welcome to coding";

use "endl" line manipulator...which is a newline

#include<iostream>
#include<cstdlib.h>
using namespace std;
int main()
{
cout<<"Hello world"<<endl;
cout<<endl;
cout<<"welcome to coding";
return 0;
}
