Chapter 2.1, Problem 12STQ

In the Programming Tip entitled “Type Casting a Character to an Integer,” you saw that the following does no: display the integer 7:

that symbol = ‘7’;

System.out.printin((int) symbol);

Thus, (int) symbol does not produce the number corresponding to the digit in symbol. Can you write an expression that will work to produce the integer that intuitively corresponds to the digit in symbol, assuming that symbol contains one of the ten digits 0 through 9? (Hint: The digits do correspond to consecutive integers so if (int) ‘7’ is 55, then(int) ‘8’ is 56.)
