Explanation:

No number is really ever random. It all has a seed, which is an initial value for the 'random' number to be generated. The rand() function uses an equation to generate its value, and all its 'random' value depend on the first number you plug in into your equation. The initial number you plug into your equation is what srand() do.

If you just call rand() alone without calling srand() then the generated numbers will automatically use srand(1) as a default seed. Using the same srand() value will always yield the same sequence of numbers.

To get a number between 0 and 9, take the modulus of it with 10 because modulus give you the remainder, so the number rand()%10 will never be equal to 10 or greater.

2.31 LAB: Simple statistics Part 1 Given 4 integers, output their product and their average, using integer arithmetic. Ex: If th

Elden [556K]

Answer:

Explanation:

Note: Integer division discards the fraction. Hence the average of 8, 10, 5, 4 is output as 6, not 6.75.

Note: The test cases include four very large input values whose product results in overflow. You do not need to do anything special, but just observe that the output does not represent the correct product (in fact, four positive numbers yield a negative output; wow).

Submit the above for grading. Your program will fail the last test cases (which is expected), until you complete part 2 below.

Part 2: Also output the product and average, using floating-point arithmetic.

Output each floating-point value with three digits after the decimal point, which can be achieved as follows: System.out.printf("%.3f", yourValue);

Ex: If the input is 8, 10, 5, 4, the output is:

import java.util.Scanner;

public class LabProgram {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

int num1;

int num2;

int num3;

int num4;

num1 = scnr.nextInt();

num2 = scnr.nextInt();

num3 = scnr.nextInt();

num4 = scnr.nextInt();

double average_arith = (num1+num2+num3+num4)/4.0;

double product_arith = num1*num2*num3*num4;

int result1 = (int) average_arith;

int result2 = (int) product_arith;

System.out.printf("%d %d\n",result2,result1);

System.out.printf("%.3f %.3f\n",product_arith,average_arith);

}

expected output : 1600.000 6.750
