A basic program to find the area of a square

1 answer:

4 0

The area of a square is simply the square of the side. So, you only need to write a program that receives a number as input, which is the side of the square, and returns that number squared, which will be the area of the square.

You didn't specify any language, so for example here's a C implementation that receives the side from the user and returns the area:

#include <stdio.h>

int main()

{

double side, area;

do{

printf("Enter the side of the square (must be >0): ");

scanf("%lf", &side);

} while(side<=0);

area = side * side;

printf("The area is %lf", area);

}

In mathematics, "quadrant I" of the cartesian plane is the part of the plane where x and y are both positive. Given a variable,

lbvjy [14]

Answer:

#include <iostream>

using namespace std;

struct Cartesian {

double x;

double y;

};

int main() {

// creating a pointer p of type struct Cartesian

struct Cartesian *p = new Cartesian ;

cout << " Enter x: ";

// accessing the structure variable x by arrow "->"

cin >> p->x;

cout << "Enter y: ";

// accessing the structure variable y by arrow "->"

cin >> p->y;

// expression to check whether x and y lie in Quadrant 1

if (p->x > 0 && p->y > 0) {

cout << "X and Y are in Quadrant 1 ";

}

else

{

cout << "x And y are not in Quadrant 1";

}

// deleting the struct pointer p

delete p;

return 0;

}

Explanation:

in order to locate memory in heap, keyword "new" is used in C++ so,

struct Cartesian *p = new Cartesian ;

in order to access data members of the structure using pointer we always use an arrow "->". otherwise a dot oprerator is used to access data members.

in order to check whether x and y lie in 1st quadrent, we must use && operator in our if condition. so

if (p->x > 0 && p->y > 0)

&& will return true iff x and y both are +ve.

deleting the struct pointer p is important beacuse we are allocating memory in heap so heap memory should be used a resource and must be release when not needed otherwise it can cause memory leakage problems. so

delete p;

2. In many jurisdictions a small deposit is added to containers to encourage people to recycle them. In one particular jurisdict

RUDIKE [14]

Answer:

Here is the Python program:

small_container = int(input("Enter the number of small containers you recycled?"))

large_container = int(input("Enter the number of large containers you recycled?"))

refund = (small_container * 0.10) + (large_container * 0.25)

print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund)))

Explanation:

The program first prompts the user to enter the number of small containers. The input value is stored in an integer type variable small_container. The input is basically an integer value.

The program then prompts the user to enter the number of large containers. The input value is stored in an integer type variable large_container. The input is basically an integer value.

refund = (small_container * 0.10) + (large_container * 0.25) This statement computers the refund that will be recieved for returning the small and larger containers. The small containers holding one litre or less have a $0.10 deposit so the number of small containers is multiplied by 0.10. The large containers holding more than one litre have a $0.25 deposit so the number of large containers is multiplied by 0.25. Now both of these calculated deposits of containers of each side are added to return the refund that will be received for returning these containers. This whole computation is stored in refund variable.

print("The total refund for returning the containers is $" + "{0:.2f}".format(float(refund))) This print statement displays the refund in the format given in the question. The output includes a $ sign and displays exactly two decimal places by using {0:.2f} where .2f means 2 decimal places after the decimal point. Then the output is represented in floating point number using. format(float) is used to specify the output type as float to display a floating point refund value up to 2 decimal places.
