The following YACC snippet is used to implement a grammar of an expression. The expressions are : E -> E+E E-> E'E E-> id program: program expr '\n' { printf("Xd\n", S2); } expr: { SS - $1; } { SS - $1 + $3; } { $S - $1 - $3; } INTEGER I expr + expr I expr '-' expr Modify the above code to handle the following grammar rules: E-> Add E E E -> Sub EE E-> Mul EE E-> Div EE E-> id, where Add, Sub, Mul, and Div are used to implement Addition, subtraction, multiplication, and division operations respectively.

Define a structure type to represent a common fraction. Write a program that gets a fraction and displays both the fraction and the fraction reduced (by using greatest common divisor (GCD) function) to lowest terms using the following code fragment: The fraction is supposed to have a numerator and denominator.Code fragment: //starts here frac = get_fraction(); print_fraction(frac); printf(" = "); print_fraction(reduce_fraction(frac)); // ends here
Computer Science A parser: parse if statement and show any syntax errors found. The project has to accept input from the user, read the input and parse the statement character by character. The project has to identify any syntax errors in the entered C++ statement and show the user the errors. You can identify the errors by comparing the input to the saved grammar rules and find the problem within the user input.

Assignment 16: Iteration Control Structure - Hands on practice Hint: Consider numbers 1 to 10, for each number find the odd multiples. Example, for 1, it should be 1, 3, 5, 7, 9 Objective: Given a real world problem, implement the logic and solve the problem using appropriate constructs (sequen- tial, selection, iteration) using an object oriented program- ming language (Java) for 2, it should be 2, 6, 10, 14, 18 Estimated time: 50 minutes Summary of this assignment: In this assignment, you have learnt the implementation of iteration control structures. Problem Description: Write simple java programs to implement the following prob- lems. 1.Find the sum of first 5 numbers (1 to 5) using for loop End of document statement 2.Find the product of first 5 numbers (1 to 5) using while loop statement 3.
