C Programming Assignment Solution - Flex and Bison

The provided C code is a program that takes user input in the form of boolean values (TRUE or FALSE) and performs various boolean calculations based on the user's input. The user can enter boolean expressions using TRUE, FALSE, and logical operators such as AND (&), OR (|), and NOT (!).

Here's a brief explanation of how the program works:

1. The program asks the user to input boolean values and boolean expressions in a specific format.

2. The user is expected to enter boolean values as TRUE or FALSE, and boolean expressions using the operators & (AND), | (OR), and ' (NOT). The format is as follows:

   a. To input TRUE AND FALSE, the user should enter: TRUE FALSE & b. To input TRUE OR FALSE, the user should enter: TRUE FALSE | c. To input NOT TRUE, the user should enter: TRUE'

3. The program parses the user's input to extract individual characters representing the boolean values and operators.

4. The characters representing boolean values (T/t for TRUE and F/f for FALSE) are converted into integer values (1 for TRUE and 0 for FALSE) for condition checks.

5. The program then evaluates the boolean expressions according to the input and prints the output, which can be either true or false.

6. The program accounts for different cases such as negation (!), AND (&), and OR (|) to calculate the final boolean value.
