What is the difference in the way computers store numeric data and non-numeric data?

1 answer:

3 0

Both numeric and non-numeric data have different ASCII codes, that will be the first difference. Second, numeric data are stored in float, double, and int variables while non-numeric data are stored in char. However, both can be stored in a String variable if and only if the desired data to be stored will not be used for computuation using mathematical operations such as addition.

To store a non-numeric data in an array, the array must first be declared as a String variable array while a numeric data can be stored in an array once the array which will store the numeric data is declared as an integer, double, or float variable.

When do you use a for loop instead of a while loop? (There may be more than one answer.)

Answer:

- You know how many times you want the loop to run.

- When there is a defined start and end.

Explanation:

Required:

When to use for instead of while loop?

First, it should be noted that both for loop and while loop are used for iteration. However, depending on the scenario; there is preference on one to the other.

The basic syntax of for loop is:

$for(start;end;condition)\{\}$

The condition could either be increment or decrement

The basic syntax of while loop is:

$while(condition)\{\}$

The condition could be any condition whatsoever

Analyzing the options one after the other.

1. How many times the loop to run.

The for loop is preferred here because of the simplicity of the for loop.

2. & 3. Both the for and while loops are used for code repetition and to perform number calculations

4. Defined start and end.

From the syntax of the for loop

$for(start;end;condition)\{\}$

A for loop has a definite start and end in its basic syntax and is more preferable to use instead of a while loop.

Hence, 1 & 4 answer the question

Write a program that prompts the user to enter the center and a point on the circle. The program should then output the circle’s

sergij07 [2.7K]

Here is the code in C++.

#include <bits/stdc++.h>

using namespace std;

// function to calculate distance between two points

double distance(int a,int b,int c,int d )

{

// return the distance between center and point

return sqrt(pow(c - a, 2) +

pow(d - b, 2) * 1.0);

}

// driver function

int main()

{

// variables to store coordinates

int x1,y1,x2,y2;

cout<<"Please Enter the center(x y) of the circle: ";

//reading center

cin>>x1>>y1;

cout<<"\nPlease Enter a point(x1 y1) on the circle:";

//reading point

cin>>x2>>y2;

// calling distance() function with 4 parameters

double rad=distance(x1,y1,x2,y2);

// calculating Radius and print

cout<<"Radius of circle is: "<<rad<<endl;

// calculating Diameter and print

cout<<"Diameter of circle is: "<<2*rad<<endl;

// calculating Circumference and print

cout<<"Circumference of circle is: "<<2*3.14*rad<<endl;

// calculating Area and print

cout<<"Area of circle is: "<<3.14*rad*rad<<endl;

return 0;

}

Explanation:

First it will read coordinates of center and point on the circle.The distancebetween center and point on circle is Radius. Call distance() function withfour parameters which are coordinates of center and point. This will return the value of Radius. Diameter is 2 times of Radius.Diameter of a circle is 2*3.14*Radius. and Area of the circle is calculate as 3.14*Radius*Radius. After finding these value print them.

Output:

Please Enter the center(x y) of the circle: 0 0

Please Enter a point(x1 y1) on the circle: 3 4

Radius of circle is: 5

Diameter of circle is: 10

Circumference of circle is: 31.4

Area of circle is: 78.5
