Comparing user-inputted characters in C

Question

The following code snippets are from a C program.

The user enters Y or N.

char *answer = \'\\0\';

scanf (\" %c\", answer);

if (*answer == (\'Y\' ||         


        

Answer 1

answer shouldn't be a pointer, the intent is obviously to hold a character. scanf takes the address of this character, so it should be called as

char answer;
scanf(" %c", &answer);

Next, your "or" statement is formed incorrectly.

if (answer == 'Y' || answer == 'y')

What you wrote originally asks to compare answer with the result of 'Y' || 'y', which I'm guessing isn't quite what you wanted to do.
