Answer with Explanation

Let's analyze the code step by step to determine the values of n and ch.


char c = 'A';
int n = c + 1;
char ch = (char)n;

  1. Value of c:

    • c is assigned the character 'A'.
    • The Unicode (or ASCII) value of 'A' is 65.

  2. Calculation of n:

    • n is calculated as c + 1.
    • Given that c is 65, the calculation will be 65 + 1, which results in 66.

    Thus, n will be 66.

  3. Value of ch:

    • ch is assigned (char)n.
    • The value of n is 66, so ch will be (char)66.
    • The character corresponding to the Unicode value 66 is 'B'.

Summary:

  • The value of n is 66.
  • The value of ch is 'B'.
