Questions and Answers

When a character is put into a char variable, what is the actual value stored?

  • The ASCII value of the character (correct)
  • The character itself
  • The character's Unicode value
  • A number between 0 and 255

What is the relationship between characters and their assigned ASCII values?

  • The relationship is meaningful and has a logical basis
  • The relationship is based on the character's frequency of use
  • The relationship is arbitrary and has no particular reason (correct)
  • The relationship is determined by the keyboard layout

What is the difference between the value 5 and the character '5'?

  • There is no difference, they both represent the same value
  • The value `5` is a numeric value, while `'5'` is a character value (correct)
  • The value `5` is a binary value, while `'5'` is a decimal value
  • The value `5` is a floating-point value, while `'5'` is an integer value

What is the significance of the ASCII values when it comes to characters in programming?

<p>ASCII values are used to represent characters in programming, allowing the compiler to translate between characters and their corresponding numeric values.</p> Signup and view all the answers

What is the purpose of the agreement between the keyboard, compiler, and screen regarding character-to-value mapping?

What is the difference between the value 5 and the character '5' in programming?

<p>The value 5 is different from the character '5' because the character '5' is actually represented by the ASCII value 53.</p> Signup and view all the answers

Explain why the mapping between characters and ASCII values is considered arbitrary.

<p>The mapping of characters to ASCII values is arbitrary because there is no inherent reason why a specific character is assigned a particular numeric value.</p> Signup and view all the answers

Explain the importance of consistency among the keyboard, compiler, and screen in character-to-value mapping.
