C programming validating input

You can also check whether a character is an alphabet or not using isalpha() function.

I'm working on a numerical palindrome program for class.

Take a expression as input and store it in the array.

If “)” encounters, then pop the element of the array. If the number of “(” and “)” are equal, then the expression is correctly parenthesized. Use variable top to denote the top element of the array stack[]. If the variable top is equal to -1, then the expression is correctly parenthesized.

I prefer only to use exceptions for less frequent error conditions.

This was especially dangerous, because Internet Explorer, when it viewed a Web page with a link to a MIDI file, would automatically load the file and try to play it. An attacker could simply post a Web page that when viewed would make the browsing user's computer erase all its files, send all its confidential files elsewhere by e-mail, crash, or do whatever else the attacker wanted.

And, the ASCII value of uppercase alphabets are from 65 to 90.

If the ASCII value of the character entered by the user lies in the range from 97 to 122 or from 65 to 90, that number is an alphabet.

LB, that portion you are quoting is what the instructor wrote to instruct us as to what this stub's function is. The number will be used in another part of the program.
