java - Adding char and int

Question

To my understanding a char is a single character, that is a letter, a digit, a punctuation mark, a tab, a space or something similar. And therefore when I do:

char c = '1';
System.out.println(c);

The output 1 was exactly what I expected. So why is it that when I do this:

int a = 1;
char c = '1';
int ans = a + c;
System.out.println(ans);

I end up with the output 50?

Answer 1

You're getting that because it's adding the ASCII value of the char. You must convert it to an int first.
