1 Data Encoding Characters

2 ASCII Question: What is the ASCII code for C?
Computers have to be able to represent letters and symbols as well as numbers. Basically, the idea is to give each character a number as a code and store the codes and their meanings in a table. A common code is ASCII - the American Standard Code for Information Interchange. Symbol Binary A B C D E F This uses seven bits to store characters. Seven bits is enough to code 128 different characters. Question: What is the ASCII code for C? Complete tasks 6.1 to 6.5.
