Print 42

Created on May 22, 2024 by Julien Palard

Write a program displaying the number 42.

What you'll learn

In this exercise you'll learn to use a function by trying the printf function from stdio.h.

A function is a named thing that does something specific:

• the printf function displays what's given to it,
• the strlen function measures the length of the string we give to it,
• …

The syntax to make a function work is called a "function call", to make printf display the string "Hello world" the syntax is:

printf("Hello world\n");

or:

printf("%s\n", "Hello world");
