The program below is able to calculate the area of a circle inscribed in a Square.

<h3>What is a program?</h3>

A program is a set of instructions given to the computer with specific end results in mind.

Sample program in Java

// Java Program to find the area of

// an inscribed circle in a square.

import java.io.*;

class GFG {

static double PI = 3.14;

// Function to find area of an

// inscribed circle in a square.

static double areaOfInscribedCircle(float a)

{

return ( PI / 4 ) * a * a;

}

// Driver code

public static void main (String[] args)

{

float a = 8;

System.out.println("Area of an inscribed"

+ " circle: " + areaOfInscribedCircle(a));

}

Answer:

//import the necessary class

import java.util.Scanner;

//Begin class definition

public class ConvertToCelsius{

//Begin main method

public static void main(String []args){

//Create an object of the Scanner class

Scanner input = new Scanner(System.in);

//Display the aim of the program

System.out.println("**Program to convert from Fahrenheit to Celsius**");

//Prompt the user to enter the temperature in Fahrenheit

System.out.println("Please enter temperature in Fahrenheit");

//Receive the user's input

//And store in the appropriate variable

double tempF = input.nextDouble();

//Convert the temperature to Celsius using

//C = (9.0 / 5) * (F - 32)

//C = temperature in Celsius, F = temperature in Fahrenheit

double tempC = (9.0 / 5) * (tempF - 32);

//Display the result

System.out.println("The temperature in degree Celsius is: ");

System.out.println(tempC);

return;

} //End of main method

} //End of class definition

Sample Output

**Program to convert from Fahrenheit to Celsius **

Please enter temperature in Fahrenheit

>> 32

The temperature in degree Celsius is:

0.0

Explanation:

The above code has been written in Java and it contains comments explaining important lines of the code. Please go through the comment. Snapshots of the program and a sample output have been attached to this response.

ikadub [295]

In this exercise we have to use the knowledge of computational language in C++ to write a code that program to evaluate the following postfix expression. the value of each variable must be asked from the user during the execution time.

<h3>Writting the code:</h3>

#include <bits/stdc++.h>

using namespace std;

// CREATED A CLASS STACK

class Stack

{

public:

int top;

unsigned sz;

int* ar;

};

// VARIOUS STACK FUNCTIONS

Stack* makeStack( unsigned sz )

{

Stack* stack = new Stack();

// BASE CONDITION

if (!stack) return NULL;

stack->top = -1;

stack->sz = sz;

stack->ar = new int[(stack->sz * sizeof(int))];

if (!stack->ar) return NULL;

// RETURNING THE STACK

return stack;

}

// CHECKING IF THE STACK IS EMPTY

int isEmpty(Stack* stack)

{

return stack->top == -1 ;

}

// CHECKING THE TOP OF THE STACK

int whatAtTop(Stack* stack)

{

return stack->ar[stack->top];

}

// POPPING OUT OF A STACK

int pop(Stack* stack)

{

if (!isEmpty(stack))

return stack->ar[stack->top--] ;

return '$';

}

// PUSHING IN THE STACK

void push(Stack* stack, int op)

{

stack->ar[++stack->top] = op;

}

// EVALUATING POSTFIX STARTS HERE

int postfixEvaluator(string res)

{

// CREATING STACK

Stack* stack = makeStack(res.length());

int i;

// BASE CONDITION

if (!stack) return -1;

for (i = 0; res[i]; ++i)

{

// CHECK FOR SPACES

if (res[i] == ' ')continue;

// CHECK FOR THE DIGIT

else if (isdigit(res[i]))

{

int N = 0;

// EXTRACT THE NUMBER OUT OF STACK

while (isdigit(res[i]))

{

N = N * 10 + (int)(res[i] - '0');

i++;

}

i--;

// PUSH THE NUMBER IN STACK

push(stack, N);

}

// POPPING AND ARITHMETIC OPERATIONS

else

{

int pos1 = pop(stack);

int pos2 = pop(stack);

switch (res[i])

{

case '+': push(stack, pos2 + pos1); break;

case '-': push(stack, pos2 - pos1); break;

case '*': push(stack, pos2 * pos1); break;

case '/': push(stack, pos2 / pos1); break;

}

return pop(stack);

}

// MAIN CODE

int main()

{

string tes;

getline(cin, tes);

string tmp = "";

string res = "";

for (int i = 0; i < tes.length(); i++) {

if (tes[i] <= 'z' and tes[i] >= 'a') {

tmp += tes[i];

} else if (tes[i] == ' ' and (tes[i - 1] <= 'z' and tes[i - 1] >= 'a')) {

cout << "Enter the value of " << tmp << ": ";

int x; cin >> x;

res += (to_string(x));

res += ' ';

tmp = "";

} else {

res += tes[i];

}

cout << "\nThe postfix expression is : " << res;

cout << "\nThe result is : " << postfixEvaluator(res);

return 0;

}
