2. (5.12 in 8e) Answer each of the following questions: a) What does it mean to choose numbers "at random"? b) Why is the rand function useful for simulating games of chance? c) Why would you randomize a program by using srand? Under what circumstances is it desirable not to randomize? d) Why is it often necessary to scale and/or shift the values produced by rand? 3. Define an array of 100 ints, and write a loop (including the body) to initialize every element in the array to 0. You can name the array whatever you'd like. 4. In C, strings have a terminating character at the end of the array, while, for example, integer arrays do not. Why do you think this is?

Question 4: (30 marks) A Math teacher is teaching Math course to a set of classes (each class may have different number of students) and want to check the behavior of his students in a homework report. The teacher gave the classes the same exam and marked their answer and wants to know the class whose students got the highest average. Help the teacher in the required analysis of student’s marks by implementing a Java program ClassAverageMArks2DimmArray using 2-dimensional array to store the students marks and then compute the average of each class student’s marks. The program has the following specification: • A Method titled averageClassMarks for computing the average (as double) of a class students marks (given to the method as a single-dimensional array) • Another Method titled averageAllClassesMarks for computing the average (as single array of double) of all the classes class student’s marks (given to the method as a 2dimensional array). This method has to repeatedly call the…
2, Towers of Hanoi Problem. (10 points) The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. Answer the following questions. (1) Determine a state representation for this problem. (4points) (2) What is the size of the state space? (3 points) (3) Supposing K=3, N=4, what is the start state by using your proposed state representation method and what is the goal state? (3 points)

[using C++]Masterchef pankaj recently baked a big nepotialn pizza that can be represented as a grid of N rows and M columns, each cell can be either empty or contain a jalapeno, pankaj wants to cut out a sub-rectangle from the pizza which contains even number of jalapenos. Before cutting such a sub-rectangle, he is interested in knowing how many sub-rectangles are there which contains even number of jalapenos.First line of input consist of two integers P and Q. Each of the next P lines contains a string of length Q, j-th character of i-th string is 1 if the corresponding cell contains a jalapeno otherwise it's 0.Output a single integer, the number of sub rectangles which contains even number of jalapeno.Sample Input:2 22101Output:5
(c) Implement the function printer in C so that given the statements below, the printer function would print: Word 1 is one. The first letter of the word is o Word 2 is two. The first letter of the word is t Word 3 is three. The first letter of the word is t Word 4 is four. The first letter of the word is f Word 5 is five. The first letter of the word is f The printer function should be capable of handling arrays of any size. void printer(int sizeofNums, *char y[]); //prototype char a[] = "one"; char b[] char c[] char d[] char e[] char *nums[] %3D "two"; = "three"; "four"; "five"; %3D = { a,b,c,d,e }; printer (sizeof(nums), nums);
2 Problem Statement You are given a number n. There is an array of strings that contains all the binary strings of length n where each string represents the plantation system where '1' represents plant A and '0' repres According to research if any two plant A comes together then they will stop the growth of the neighbors also. Your task is to find the number of plantations in which growth will not be affected. Note-Since the answer can be too long, return the answer modulo 1e9+7. Constraints: 1 <= n <= 100000 B Rules E Finish Input Format The first line contains an integer n. Output Format Print k-the number of strings satisfying the condition.
