Statistics are often calculated with varying amounts of data stored in a file. Write a program that takes any number of non-negative integers as input, and outputs the average, min and max. Prompt user for the input file name, open the file, read and process the numbers in the file.
Answers
Following are the program explanation, program, and output to the given question:
Program Explanation:
Import package.Defining a class Main.Defining the main method.Defining a string variable "str" and define a Scanner class object to input the"str" value.After input, the string value of a Scanner class object is created that takes the "str" value in the parameter.In the next step, the "ArrayList" class object is declared that uses a while loop to add value to the list.In the condition statement an if block is defined that check ArrayList value equal to 0, and print the message.In the else block, a float variable "sum" and three integer variable "ctr, min, and max " is declared that check its value and prints its value with the message.Program:
import java.io.*;//import package
import java.util.*;//import package
public class Statistics //defining a class Statistics
{
public static void main (String[] asx)//defining main method
{
String str;//defining a string variable str
Scanner sob= new Scanner(System.in);//defining Scanner class object to input value
System.out.println("Enter value: ");//print message
str= sob.nextLine();//input value
Scanner s = new Scanner(str);//using Scanner class to take value str in parameter
List<Integer> val = new ArrayList<Integer>();//defining an ArrayList class
while(s.hasNextInt())//defining a while loop in add value
{
val.add(s.nextInt());//using add method to add value
}
if(val.size() == 0)//defining if block that check ArrayList value equal to 0
System.out.println("The File is empty");//print message
else//else block
{
float sum = 0;//defining float variable
int ctr = 0, max = Integer.MIN_VALUE, min = Integer.MAX_VALUE;//defining integer variable that hold value
for(Integer a:val)//defining a for loop that check ArrayList
{
ctr = ctr + 1;//adding value in ctr variable
sum = sum + a;//adding value sum variable
if(min > a)//use if to check min value greater than a
min = a;//holding value in min
if(max < a)//use if to check max value less than a
max = a;//holding value in max
}
System.out.print("Average = ");//print message
System.out.println(sum/ctr);//print average value
System.out.print("Minimum value = ");//print message
System.out.println(min);//print min value
System.out.print("Maximum value = ");//print message
System.out.println(max);//print max value
}

Answer:
A high-level language is one that is user-oriented in that it has been designed to make it straightforward for a programmer to convert an algorithm into program code. A low-level language is machine-oriented. Low-level programs are expressed in terms of the machine operations that must be performed to carry out a task. In easy words high level languages are near to human beings and far from computer and low level languages are near to computers and far from human understandings.

The output signal from an analogue sensor is sampled every 195 µs to convert it into a digital representation. What is the corresponding sampling rate expressed in kHz?
According to the Sampling Theorem, for this sampling rate value, what approximately could be the highest frequency present in the signal, in kHz, assuming the lowest frequency is very close to zero?
If each sample is now quantised into 512 levels, what will be the resulting bitrate in kbps?
Give your answer in scientific notation to 2 decimal places.
Hint: you need to determine the number of bits per sample that produces 512 quantisation levels.
Answers
Answer:
A sample rate is just reciprocal of the sample period. According to sampling theorem the highest frequency in single would be [tex]5.13/2=2.565 KHz.[/tex][tex]2^8=512[/tex] So you will need 8 bits to represent.[tex]8 bits \times5.128\times(10)^3[/tex]samples [tex]=41.026[/tex] bits per second.Explanation:
Sample period of 1 millisecond [tex]=1 kHz.[/tex]
Thus a sample period of [tex]0.195[/tex] milliseconds is
[tex]1/0.195=5.12820513 Hz[/tex]
To determine the sample after [tex]512[/tex] levels quantization, we need to find bits per sample that produces [tex]512[/tex] quantization levels.
Thus,
[tex]2^8=512[/tex]
So you will need 8 bits to represent.
8 bits [tex]\times5.128\times(10)^3[/tex] samples [tex]=41.026[/tex] bits per second.

write a c++ program to calculate the factorial of a number
Answers
Answer:
#include <iostream>
int factorial(int n) {
return (n > 1) ? n*factorial(n-1) : 1;
}
int main() {
std::cout << factorial(5);
}
Explanation:
Above is an approach using recursion.
It will output 120, which is 5! = 5*4*3*2*1
#include <iostream>
using namespace std;
int main() {
// Declare the variables
int n = 19;
long int factorial = 1;
// Each time, the factorial multiplies by integers from 1 to the maximum number.
for(int i = 1; i <= n; i = i + 1) {
factorial = factorial * i;
}
// Display the factorial
cout << factorial;
return 0;
}
EXPLANATIONDeclare n and factorial as integers and long integers.
The "for loop" runs from 1 to the maximum number and increments by 1. The factorial multiplies each time by integers from 1 to n.
Print the factorial.

(I tried using strVar.insert(partStr, str2) but was unsuccessful. I don’t know where I’m messing up. Thank you for your help. I’ve been trying to alter this code for a while now)
Answers
Answer:
Use the .find() function in your first string to give you an index.
Explanation:
Hi! I'm guessing you're taking COP2334 like me. A T.A. helped me figure out what I needed, so I'm passing it on.
Basically, you're given three strings and no integer to use as an index in order to insert the second line. Since you are required to have an index to use the .insert() function, this is "tear-out-my-hair" frustrating. What I failed to remember was that it is totally possible to use a function inside another function to get what you need!
You have been given is a hint as to where str2 goes, in the form of your 3rd string. If I'm right, all of the tests the system will run (mine is in Zybooks) will give a 3rd string that is inside the first string.
String 1: strVar: "FuzzyBear"
String 2: str2: "Wuzzy"
String 3: partStr "Be"
Open your statement with strVar and use the insert.() function. In the insert function, you are required to give a place to start, (your index), then what you want to insert. Your index will be the .find() function, searching in StrVar for partStr. The second part of the .insert() function is str2.
Hope that helps!
