• All your files should end with a new line
• A README.md file, at the root of the folder of the project, is mandatory
• Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl

• In the following examples, the main.c files are shown as examples. You can use them to test your functions, but you don’t have to push them to your repo (if you do we won’t take them into account). We will use our own main.c files at compilation. Our main.c files might be different from the one shown in the examples

Tasks

0. Infinite Multiplication

Write a program that multiplies two positive numbers:

• Usage: mul num1 num2
• num1 and num2 will be passed in base 10
• Print the result, followed by a new line
• If the number of arguments is incorrect, print Error, followed by a new line, and exit with a status of 98
• num1 and num2 should only be composed of digits. If not, print Error, followed by a new line, and exit with a status of 98
• You are allowed to use more than 5 functions in your file

You can use bc (man bc) to check your results.
