This is the first problem in the C++ domain and under the Introduction sub-domain. Just print the message ' Hello World! " in the console.

In C++ for printing any message or printing the output in the console string, we always use a " cout " and "<< " operator after that double quotes and between the double quotes put the message, in this case, we will put " Hello world! "

Example:

cout<<"Hello, World!";

As we know that C++ is an extended version of C language, C++ support all the functionality of C language so we also can use the " printf() " function instead of " cout<< ", but here our solution is in C++ so " cout<< " is better but we can use " printf() " as well.

Example:

printf("Hello, World!");
