#include<iostream> #include<array> #include<sstream> std::array<int,10> get_frequency (int range_min, int range_max) { if (range_max<range_min) std::swap (range_min, range_max); std::array<int,10> digit {}; for (int count {range_min}; count<=range_max; ++count) { std::stringstream ss {}; ss << count; std::string s {}; ss >> s; for (auto c : s) { ++digit[c-'0']; } } return digit; } int main () { std::array<int,10> digit {}; digit = get_frequency(1, 89); std::cout << "In the range 1 to 89...\n"; for (int d {0}; d<10; ++d) { std::cout << "\tthe digit " << d << " appears " << digit[d] << " times.\n"; } } Output: In the range 1 to 89... the digit 0 appears 8 times. the digit 1 appears 19 times. the digit 2 appears 19 times. the digit 3 appears 19 times. the digit 4 appears 19 times. the digit 5 appears 19 times. the digit 6 appears 19 times. the digit 7 appears 19 times. the digit 8 appears 19 times. the digit 9 appears 9 times.

How many digits are there in a check number?

A check digit is typically a single digit 0-9 (or it may be a single byte with value 0-255), which is calculated from a formula, using the other digits in a string of digits. The digit is then appended, usually at the end of the string of digits before encoding for transmission over a communications network or creating a barcode. The receiver (or barcode scanner) has the same formula, which was used to create the check digit, and performs the same operation, then checks to see if the digit that was received (or scanned) is the same as the calculated digit. If they match, then a successful transmission is assumed. Disk drives also use check digit methods to see if data read in might be erroneous, due to imperfections in the disk surface.

What is a check digit?

A check digit is the twelfth and final number in a USPS bulk mail barcode string and is used by the USPS to detect barcode errors. The first eleven digits depict three groupings: the delivery zone (your 5-digit ZIP code), the region within the zone (+4) and the exact location for the mail drop (+2 , the delivery point (DP), or the last two digits of a mailbox or flat). The check digit is calculated by adding up the eleven digits, then subtracting the last digit of that result from 10. To illustrate this, the total, when adding up the 11 digits associated with the company I work for, is 34. Since 4 is the last digit in that number, I subtract it from 10 and get our check digit, 6. You can also use an online ZIP+4 lookup that returns the check digit at the end of the barcode string. Try http://bit.ly/ZIPplus4 Type in your address and push Search, then scroll all the way to the bottom of the page for easy-to-read Return Results.
