Echo an Integer

Write a program that reads a single whole number from standard input and prints it back exactly as it was entered, with nothing extra. This is the most basic form of user input: read one value with scanf and echo it. Do not print any label, spaces, or newline — just the number itself.

Expected Output:

42

= newline. No newline after the last line.
