Question
In this challenge, we practice reading input from stdin and printing output to stdout.In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout. For example, let's say we declare the following variables:string s;int n;
Solution
Sure! In this challenge, we will be reading input from stdin and printing output to stdout. To do this in the given language, we can use the following steps:
-
Declare the necessary variables:
- Declare a variable
sof type string to store the input. - Declare a variable
nof type int to store another input.
- Declare a variable
-
Read input from stdin:
- Use the appropriate method or function to read a single whitespace-separated token of input. In this case, we can use
cinto read the input and store it in the variables. - Similarly, use
cinto read another input and store it in the variablen.
- Use the appropriate method or function to read a single whitespace-separated token of input. In this case, we can use
-
Process the input:
- At this point, you can perform any necessary operations or calculations on the input variables
sandn.
- At this point, you can perform any necessary operations or calculations on the input variables
-
Print output to stdout:
- Use the appropriate method or function to print the output to stdout. In this case, we can use
coutto print the output. - You can print the output directly or store it in a variable before printing.
- Use the appropriate method or function to print the output to stdout. In this case, we can use
Remember to include any necessary headers or libraries at the beginning of your code.

n this challenge, we will learn some basic concepts of C that will get you started with the language. You will need to use the same syntax to read input and write output in many C challenges. As you work through these problems, review the code stubs to learn about reading from stdin and writing to stdout.TaskThis challenge requires you to print on a single line, and then print the already provided input string to stdout. If you are not familiar with C, you may want to read about the printf() command.ExampleThe required output is:Hello, World!
