Output

To print something in C++ we will use the object cout with the operator << . The message you want to output must be enclosed with double quotes. For example:


              1234567
            
#include &lt;iostream&gt;
using namespace std;
 
int main() {
 &nbsp&nbsp&nbsp&nbspcout << "I love C++!";
&nbsp&nbsp&nbsp&nbspreturn 0;
}

To get the same result, you can also write the code without using namespace std :

Pay attention that you can use the multiple insertion operator and add as many cout objects as you want:


              12345678
            
#include &lt;iostream&gt;
using namespace std;
 
int main() {
&nbsp&nbsp&nbsp&nbspcout << "I love programming! ";
&nbsp&nbsp&nbsp&nbspcout << "I love C++" << " and " << "Python!";
 &nbsp&nbsp&nbsp&nbspreturn 0;
}

Every cout object or << operator doesn’t write your code to a new line.

Everything was clear?
