Explanation:- This is the first problem in C++ domain and under 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 whatever 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 " 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!");
