Today we will be solving Say “Hello, World” with C++ which is a Hacker Rank problem. After going through this post you will get to know how to solve simple hello world like problems in C++.
Objective
This is a simple challenge to help you practice printing to stdout. You may learn how to print in C/C++ before attempting this question.
We’re starting out by printing the most famous computing phrase of all time! In the editor below, use either printf or cout to print the string Hello, World! to stdout.
The more popular command form is cout. It has the following basic form:
cout<<value_to_print<<value_to_print;
Any number of values can be printed using one command as shown.
The printf command comes from C language. It accepts an optional format specification and a list of variables. Two examples for printing a string are:
printf(“%s”, string); printf(string);
Note that neither method adds a newline. It only prints what you tell it to.
