This project implements a Universal Turing Machine in the C programming language. A Turing Machine is a mathematical model of computation that defines an abstract machine, which manipulates symbols on a strip of tape according to a set of rules. The universal version of this machine can simulate any other Turing machine.

• >: Move the tape head to the right.
• <: Move the tape head to the left.
• #: Initial symbol on the tape.
• _: Blank space on the tape.

1. Compile the Program: Use a C compiler to compile the code. For example, using GCC:

gcc turing_machine.c -o turing_machine

2. Run the Program: Execute the compiled program:

./turing_machine

3. Input the Transitions: Follow the prompts to input the transitions, initial state, and final states.
4. Input the String: Enter the string to be processed by the Turing machine and the initial position of the tape head.
5. Simulation: The program will simulate the Turing machine's operation and indicate whether the input string is accepted or not.

1. Example 1:

   • Transitions:

     1,a,2,b,>
     2,b,1,a,<

   • Initial State: 1
   • Final State(s): 2
   • Input String: abab
   • Initial Head Position: 0
   • Result: Accepted

2. Example 2:

   • Transitions:

     1,a,1,a,>
     1,_,2,_,<

   • Initial State: 1
   • Final State(s): 2
   • Input String: aaa
   • Initial Head Position: 0

• Ensure the input format for transitions follows the state1,symbol1,state2,symbol2,direction pattern.
• The program can be modified to handle more complex Turing machines with additional features as needed.
