Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
#include <fstream> //to manipulate files
using namespace std; //to identify objects like cin cout
int main(){ //start of main function
ifstream file; //creates an object of ifstream
file.open("random.txt"); //open method to open random.txt file using object file of ifstream
int numCount = 0; //to store the number of all numbers in the file
double sum = 0; //to store the sum of all numbers in the file
double average = 0.0; //to store the average of all numbers in the file
int number ; //stores numbers in a file
if(!file){ //if file could not be opened
cout<<"Error opening file!\n"; } //displays this error message
while(file>>number){ //reads each number from the file till the end of the file and stores into number variable
numCount++; //adds 1 to the count of numCount each time a number is read from the file
sum += number; } //adds all the numbers and stores the result in sum variable
average = sum/numCount; //divides the computed sum of all numbers by the number of numbers in the file
cout<<"The number of numbers in the file: "<<numCount<<endl; //displays the number of numbers
cout<<"The sum of all the numbers in the file: "<<sum<<endl; //displays the sum of all numbers
cout<<"The average of all the numbers in the file: "<< average<<endl; //displays the average of all numbers
file.close(); } //closes the file
Explanation:
Since the random.txt is not given to check the working of the above program, random.txt is created and some numbers are added to it:
35
48
21
56
74
93
88
109
150
16
while(file>>number) statement reads each number and stores it into number variable.
At first iteration:
35 is read and stored to number
numCount++; becomes
numCount = numCount + 1
numCount = 1
sum += number; this becomes:
sum = sum + number
sum = 0 + 35
sum = 35
At second iteration:
48 is read and stored to number
numCount++; becomes
numCount = 1+ 1
numCount = 2
sum += number; this becomes:
sum = sum + number
sum = 35 + 48
sum = 83
So at each iteration a number is read from file, the numCount increments to 1 at each iteration and the number is added to the sum.
At last iteration:
16 is read and stored to number
numCount++; becomes
numCount = 9 + 1
numCount = 10
sum += number; this becomes:
sum = sum + number
sum = 674 + 16
sum = 690
Now the loop breaks and the program moves to the statement:
average = sum/numCount; this becomes:
average = 690/10;
average = 69
So the entire output of the program is:
The number of numbers in the file: 10 The sum of all the numbers in the file: 690 The average of all the numbers in the file: 69
The screenshot of the program and its output is attached.
Answer:
Explanation:
This code was written in Java. It creates the Cars class with the requested variables and methods. It also creates the TestCars class which asks the user for the necessary inputs and then creates three Cars objects and passes the input values to the constructors. Finally, it uses the show() method on each object to call the information. A test has been created and the output can be seen in the attached image below.
import java.util.Scanner;
class TestCars{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter Car Make: ");
String make1 = in.next();
System.out.print("Enter Car Model: ");
String model1 = in.next();
System.out.print("Enter Car Year: ");
int year1 = in.nextInt();
System.out.print("Enter Car Make: ");
String make2 = in.next();
System.out.print("Enter Car Model: ");
String model2 = in.next();
System.out.print("Enter Car Year: ");
int year2 = in.nextInt();
System.out.print("Enter Car Make: ");
String make3 = in.next();
System.out.print("Enter Car Model: ");
String model3 = in.next();
System.out.print("Enter Car Year: ");
int year3 = in.nextInt();
Cars car1 = new Cars(make1, model1, year1);
Cars car2 = new Cars(make2, model2, year2);
Cars car3 = new Cars(make3, model3, year3);
car1.show();
car2.show();
car3.show();
}
}
class Cars {
String makes, models;
int years;
public Cars(String makes, String models, int years) {
this.makes = makes;
this.models = models;
this.years = years;
}
public void show() {
System.out.println("Car's make: " + this.makes);
System.out.println("Car's model: " + this.models);
System.out.println("Car's year: " + this.years);
}
}
Answer:
11: Compiler translates a high level source program into a target equivalent (machine language).
An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.
12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)
13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.
14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language
15: Stack-based language, similar to modern Java compiler byte code
16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.
17: A compiler which translates byte code into machine language immediately prior to each program execution.
18: Lisp and Prolog
19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.
21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.
