Question No: 1 of 50
The number of bytes a character takes is decided by the type of ________________ 
Options:
  1. decoding
  2. encoding
  3. size
  4. range
View Answer/Explanation:
b
Explanation:
In a stream of text, one unit of data is one character i.e. at a time we read or write a character or an array of characters. Here we should know the type of encoding before we can read characters from text stream. Based on the type of encoding used number of bytes a character takes is decided and this remains fixed throughout the stream.
