Explanation of Solution
Boolean variables:
Boolean variables are referred as “bool”, commonly used as flags which gives intimation whether the condition exists.
- • It can refer any of the two values, either “True” or “False”.
- • Flag is used to remember something or leave a sign for the other parts of the
program. - • The condition does not exist when the flag is set to false.
- • The condition exists when the flag is set to true.
Example Program:
The below program demonstrates the working of “Boolean” variables...

- Code in C++ Language STRING FLIP ALPHABET One of the simplest cryptography technique is to invert the characters such that the first character of the alphabet will be replaced to the last character, the second character be replaced to the second to the last, and so on. So all A's are turned into Z's, B to Y, C to X, and so on until X to C, Y to B, and Z to A. In a similar fashion, numeric characters will also be inverted such that 0 will become 9, 1 to 8, 2 to 7 and so on until 7 to 2, 8 to 1, and 9 to 0. Given a string composed of uppercase and lowercase letters, numbers, and spaces, your task is to invert them. You also must keep the case of the letters as is.

Programming challenge description: Little Tommy is in kindergarten on the first day of class. His teacher has taught him about inequalities today, and he is learning how to draw crocodiles to represent them. When there are two numbers, A and B, there are three options:1. If A is greater than B, then draw '>'. The crocodile's mouth is pointed toward the bigger number, A.2. If A is less than B, then draw '<'. The crocodile faces B.3. If A is equal to B, draw '='. The crocodile is confused and keeps its mouth shut.Unfortunately, Tommy does not like to do his homework, and has bribed you to write a program to do it for him. Input: The input consists of two integers A and B on a line, separated by a space. |A,B| < 2^63. Output: Print a line containing the appropriate symbol that describes the relationship between the numbers.
