C programming validating input 1945 1950 dating

I'm in my second OOP class, and my first class was taught in C#, so I'm new to C and currently I am practicing input validation using cin.

So here's my question: Is this loop I constructed a pretty good way of validating input?

In C programming, a character variable holds ASCII value (an integer number between 0 and 127) rather than that character itself.

The ASCII value of lowercase alphabets are from 97 to 122.

In nearly all secure programs, your first line of defense is to check every piece of data you receive.

If you can keep malicious data from entering your program, or at least keep it from being processed, your program becomes much harder to attack.

If “(” encounters, then push it to the separate array. Take a expression as input and store it in the array a[]. If “)” encounters, then pop the top most element of the array stack[] and decrement the variable top by 1.

Similarly, ' A' is used instead of 65 and ' Z' is used instead of 90.One obvious question is, where should the checking be performed?When the data first enters the program, or later by a lower-level routine that actually uses the data?This program determines if a given number is a palindrome.When coding it as georgewashere above did, I get this error: error LNK2001: unresolved external symbol "int __cdecl get Number(void)" (?
