Byte Exercise
Instructions:
Imagine you are building a simple text-based game. Each character in the game is represented by a single byte. You need to store the following phrase: "Welcome to the game!"
1. How many bytes would be needed to store this phrase?
2. Explain your reasoning for the number of bytes you calculated.
Exercice Correction
1. 20 bytes
2. There are 20 characters in the phrase, and each character is represented by a single byte, therefore, 20 bytes are needed to store the entire phrase.
