The C++ comments are used to insert notes into the source code and are meant only to enhance the readability of the code. The C++ comments are statements that are not executed by the compiler. .
There are two types of comments in C++.
The single line comment starts with // (double slash) and causes the compiler to ignore everything that follows the slashes on the same line. Let's see an example of single line comment in C++.
#include <iostream>
using namespace std;
int main()
{
int x = 11; // x is a variable
cout<<x<<"\n";
}The C++ multi line comment is used to comment multiple lines of code. It is surrounded by slash and asterisk (/∗ ..... ∗/). Everything within the opening /∗ and the closing ∗/ is a comment, even if it stretches over multiple lines. Let's see an example of multi line comment in C++.
#include <ostream>
using namespace std;
int main()
{
/* declare and
print variable in C++. */
int x = 35;
cout<<x<<"\n";
}
