alina1380 [7]

Answer:

public class Averager {
private int sum;
private int count;
public Averager(int sum, int count) {
this.sum = 0;
this.count = 0;
}
public int getSum(){
return sum;
}
public void add( int num){
this.sum+=num;
this.count++;
}
public int getCount(){
return this.count;
}
public double getAverage(){
double ave = (int)this.sum/this.count;
return ave;
}
}

Explanation:

Lines 1-3 contains the class declaration and the member (data fields)
Lines 4-7 is the constructor that initializes the fields to 0
Lines 8-10 is the method that returns the value of sum getSum()
lines 11-14 iss the method add() that adds a number to the member field sum and increases count by 1
lines 15 - 17 is the method that returns total count getCount()
Lines 18-21 is the method getAverage() That computes the average and returns a double representing the average values

Write a C program that gets 4 integer values from the user, namely, x1, x2, y1, and y2, and then calculates and returns the dist

lidiya [134]

Answer:

#include <stdio.h>

#include <math.h>

int main(){

float x1,x2,y1,y2,distance;

printf("x1: "); scanf("%f", &x1);

printf("y1: "); scanf("%f", &y1);

printf("x2: "); scanf("%f", &x2);

printf("y2: "); scanf("%f", &y2);

distance = sqrt((x1 - x2)*(x1 - x2) + (y1 - y2)*(y1 - y2));

printf("Distance: %f", distance);

return 0;

}

Explanation:

This line declares all required variable (i.e. the coordinates and the distance)

float x1,x2,y1,y2,distance;

The next four line prompt and get input for the coordinates

printf("x1: "); scanf("%f", &x1);

printf("y1: "); scanf("%f", &y1);

printf("x2: "); scanf("%f", &x2);

printf("y2: "); scanf("%f", &y2);

This calculates the distance

distance = sqrt((x1 - x2)*(x1 - x2) + (y1 - y2)*(y1 - y2));

This prints the calculated distance

printf("Distance: %f", distance);
