Question 4 The following context-free grammar describes part of the syntax of a Pascal-like language. Non- terminals are given in capitals and terminals in lower case. VAR represents a variable name and CONST represents a constant. The productions for ASSN-STMT are not given, as they do not affect the question. procedure STMT-LIST STMT STMT-LIST PROGRAM - STMT-LIST- | STMT do VAR = CONST to CONST begin STMT-LIST end | ASSN-STMT STMT Show the parse tree for the following input procedure do į = 1 to 100 begin ASSN-STMT ASSN-STMT end ASSN-STMT

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
Languages L2 is defined by symbols Σ={0,1}, written as follows: L2={w| w contains N number of 1 followed by N number of zeros} Q) Design a NFA that accepting the language L2. Write the formal definition as 5 tuples.
I need help in solving the question highlighted in bold for C language. Given- struct tag { char ch; int i; }; struct bTag{ float f; double d; }; struct cTag{ struct aTag a; struct bTagb; int A[5]; }; typedef struct aTag aType; typedef struct bTag bType; typedef struct cTag cType; aType a, A[5]; bType b, B[5]; cType c, C[5]; aType *pa; bType *pb; cType *pc; 1a). Implement a function void InputFunc1(cType *ptr) that will input via scanf() the members of the structure pointed to by ptr. Assume that the memory space already exist. b). Implement a function cType InputFunc2(void) that will declare a local variable as cType temp. The function will then input the values of the members of temp using scanf(). Finally, the function will return temp. c) Implement a function void InputFunc3(cType C[], int n) that will input via scanf() the elements of the array of structure C. Parameter n represents the number of elements in the array. d) Implement a function void OutputFunc1(cType…
Theory of computation: Write a program using c++ and pseudo code to check if the entering value following the grammar or not without checking if the grammar is left recursion or not: E ---> E + T | T T---> T * F | F F---> (E) | i Thanks in advance ( I hope you solve it fast with the right answer if you can't solve it leave it please! )
2. A piece of declaration code in C programming language is as follows: typedef struct { int a, b; } CELL, *PCELL; CELL foo[100]; PCELL bar ( int x, CELL y ); Write the type expression for foo and bar. 3. Write an SDT for the following grammar, which can perform type checking. The type of S is the valid type of its body. S -> id := E | if E then S | while E do S | S; S
