This is another Java program that checks whether the string is a pangram. Here, we encapsulate the operations in functions. Open Compiler public class Pangram { static int size = 26; static boolean isLetter(char ch) { if (!Character.isLetter(ch)) return false; return true; } static boo...
isNumberCustom manually checks each character of "123.45" to determine if it is a valid number. It uses std::isdigit() to check if a character is a digit. std::isdigit(char c): This function checks if the character c is a digit (0 to 9). It is a part of the <cctype> header ...

First, we will create a class Pangram with a constant size = 26 and a helper method isLetter(char ch) to check if a character is a letter. In main(), define the input string "Abcdefghijklmnopqrstuvwxyz", print it, and convert it to lowercase. Create a boolean array is_true of siz...

Solved: We have a string as an input. We need to check if it contains any characters other than digits ( ie. 0123456789) The other characters could be special
