Truth_Table.cpp

//Author : Daniyal Shahzad

//Description:
//This code will ask the user for the input of choixe table and will keep running until four entries are made. so that the
//gets the exact table he/she wants then as if the user want to continue or not. and same process will repeat until the user exits.
//Known issues: infite loop while a character is entered. Working on the issue and I will update the code in my repository if some is interested so they can look up to it.
//This will be the first program in C++. in my github repository if plagiarism is detecected it will be my repository.
