So I’m reading K&R book and I have a question regarding this code:
int c;
c = getchar();
Why do they use integer variable? Isn’t the value that getchar() returns a character? So a char would be more suitable? Please enlighten me.
getchar()needs to be able to indicate when it’s reached the end of the input. It does this by returningEOF, which is deliberately outside the validcharrange so it can’t clash with a character appearing on the input.
