LEX/FLEX program to implement a simple arithmetic calculator. It should be able to recognize negative numbers and add, subtract, multiply, divide and group sub-expressions. Sample expressions to test the program are given below. Give the source code and the runtime screen.   2+2*2 (2+2)*2 12/2+3 2*25/3

Write a C++ program: to iteratively compute Fibonacci numbers (named after an Italian mathematician). Some Fibonacci numbers are 1,1,2,3,5,8,... where the next number is found by summing the preceding two numbers. Your program is not assured of recieving good data, thus if -2 is recieved as the number of numbers, then an error should be reported.  Try n = 5, 7, 10, -3

Don't try to copy anything. If I see plagiarism then I'll reduce rating for sure.

write a program the computes nx and store the result into y You can use y = Math.pow( Mantissa, exponent)Requirements:Besides main() your program must have one method with two parameters, one double and one int n and x are positive numbers read from the keyboardif the user makes an entry that does not meet this criterion, the user must be given to opportunity retry the entry the user must be able to quit prior to entering values for n and x Your method must compute y and return the result to its caller; the caller will print the result After printing the result, the user must be queried again if there are other values to compute; if the answer is no exit the program, but if the user replies yes, then repeat the computation

Work needed in Java

Write a function that receives a positive integer n as a parameter, then it must calculate the sum 1+2+3+...+n. Finally return the result of the sum and in the main function print that result to the screen. The output of the program should be just the value of the sum. Look at the example. Input: A positive integer n Output: The result of the addition 1+2+3...+n Program execution example: Entry 6 Departure twenty-one Entry 5Output fifteen Entry 7 Departure 28

Need help to make a calculator in coding with Java.

Write a program that takes in four positive integers and outputs the number of odd numbers. (Hint: use the modulo operator to determine if a number is odd) Ex: If the input is: 1 2 3 4 the output is: 2 Below is my code so far and I'm getting back unexpected EOF while parsing. I can't figure out what I'm doing wrong. odd_number=[]number_1=int(input())number_2=int(input())number_3=int(input())number_4=int(input())if number_1%2!=0:    odd_number.append(number_1)else:    passif number_2%2!=0:    odd_number.append(number_2)else:    passif number_3%2!=0:    odd_number.append(number_3)else:    passif number_4%2!=0:    odd_number.append(number_4)else:    passprint(len(odd_number)

Here is the Python code for our Truth Table Generator function truthTable() which takes two parameters: A Boolean expression: e.g. A AND NOT (B OR C) The number of inputs: either 2, 3 or 4: A, B, C and DMain.py def truthTable(expression,inputs=2):  print("Boolean Expression:")  print("  X = " + expression.upper())  expression = expression.lower()    #replace Boolean Operators with bitwise operators  expression = expression.replace("and","&")  expression = expression.replace("xor","^")  expression = expression.replace("or","|")  expression = expression.replace("not","~")    print("\nTruth Table:")  if inputs==2:    print("  -------------")    print("  | A | B | X |")    print("  -------------")        for a in range(0,2):      for b in range(0,2):        x = eval(expression)        print("  | " + str(a) + " | " + str(b) + " | " + str(x) + " |" )        print("  -------------")          elif inputs==3:    print("  -----------------")    print("  | A | B | C | X |")    print("…

make a C program that implements the "guess my number" game.  The computer chooses a random number using the following random generator function srand(time(NULL)); int r = rand() % 100 + 1;   that  creates a random number between 1 and 100 and puts it in the variable  r. (Note that you have to include <time.h>)  Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn't find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed. After each correct guess or game over, the user decides to play again or quit and based on the user choice, the computer will make another guess and…
