- Write a program in c language to store the information of any biological entity in a structure array. Data members in the structure should be of int and char data type with source code. Also includes strings in it. Your program should read the data from user and then store in structure and display in tabular form. Need source code in simple C language.Write in C++ a polymorphic and recursive function, print(x, n, w),which can print an object, x, the given number of times, n, separated by the user’s choice of white space character, w.Both n and w must be “default arguments”. The default value of “n” must be 1 and the default value of “w” must be the space character.(1) (2) (3)NB: If any part of your solution to a question has been extracted from a book, past tests or exams, then full disclosure must be given with complete references to the source. Non-disclosures will carry heavy penalties.CS 404 Artificial Intelligence - LISP Handout 1 1. Write a program that prints teenager if age is between 13 and 19. 2.

- Please implement the follwoing problem in C++: Implement a symbol balance checker function for the Pascal programming language. Pascal allows for the following pairs: {}, (), [], begin end . All programs will begin with the word "begin" and end with the word "end". Your function should receive an ifstream object which is already open and will return true, all of the symbols match, or false, they do not. You do not have to worry about comments in the program but you do have to avoid other parts of the program's code such as assignment statements (x=y) and other expressions.3. Consider the abstract syntax for the following expression language. The constant Zero denotes 0, and the operation Succ computes successors. The operation Sum takes a list of expressions as arguments and computes its sum. IfPos returns the value of the first expression if its value is greater than 0. Otherwise, it returns the value of the second expression. You may use the function sum :: [Int] -> Int in your solution. data Expr = Zero | Succ Expr | Sum [Expr] | IfPos Expr Expr Define the semantics of the expression language as a function sem of the following type. sem :: Expr -> IntIN JS LANGUAGE Given the above parameters, implement a function that returns a string representing the plant (see the examples below for a better visualization). Examples plant("@", 3, 3, 25) "---@@@_@@@---@@@"
- Can you please help me solve this in C language? I did encounter and solve this problem with Java but I cannot seem to implement the use of structures in solving this problem. Help is appreciated, thank you. Using the concept of structures, write a program to assign passenger seats in an airplane. Assume a small airplane with seats numbered as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D The program should display the seat pattern, marking with an ‘X’ the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D Seats are assigned by specifying a number and a letter. If the user types in a seat that is already assigned, the program should say that the seat is occupied and ask for another choice. The program should run until all seats are…Q: Use recursive definition for the following languages Define the language L, having even number of a’s and even number of b’s.

- Define a C++ language float literal using regular expression. A float literal in C language has an optional exponent part. If a float literal is written without exponent part, then it must have a decimal point which can appear at the start, at the end or in the middle of digits, as in following examples: 123.456 .456 456. If float literal is written with exponent, then decimal point in mantissa part is optional, and exponent is a whole number with optional sign, as in following examples: 123e78 123e+78 123e-78 123.456e78 .456e78 456.e78Define a C++ language float literal using regular expression.
