The cost to ship a package is a flat fee of 75 cents plus 25 cents per pound.

Declare a const named CENTS_PER_POUND and initialize with 25.

Get the shipping weight from user input storing the weight into shipWeightPounds.

Using FLAT_FEE_CENTS and CENTS_PER_POUND constants, assign shipCostCents with the cost of shipping a package weighing shipWeightPounds.

#include

using namespace std;

int main() {

int shipWeightPounds;

int shipCostCents = 0;

const int FLAT_FEE_CENTS = 75;

/* Your solution goes here */

cout << "Weight(lb): " << shipWeightPounds;

cout << ", Flat fee(cents): " << FLAT_FEE_CENTS;

cout << ", Cents per lb: " << CENTS_PER_POUND << endl;

cout << "Shipping cost(cents): " << shipCostCents << endl;

return 0;

}

Using the code stub below, compute the acceleration of gravity for a given distance from the earth's center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth's center (stored in variable distCenter).

#include

using namespace std;

int main() {

double G = 6.673e-11;

double M = 5.98e24;

double accelGravity;

double distCenter;

cin >> distCenter;

/* Your solution goes here */

cout << accelGravity << endl;

return 0;

}

Given sphereRadius, compute the volume of a sphere and assign sphereVolume with the result. Use (4.0 / 3.0) to perform floating-point division, instead of (4 / 3) which performs integer division. Volume of sphere = (4.0 / 3.0) π r3 (Hint: r3 can be computed using *)

#include

#include

#include

using namespace std;

int main() {

double sphereVolume;

double sphereRadius;

cin >> sphereRadius;

/* Your solution goes here */

cout << fixed << setprecision(2) << sphereVolume << endl;

return 0;

}

A drink costs 2 dollars. A taco costs 4 dollars. Given the number of each, compute total cost and assign totalCost with the result. Ex: 4 drinks and 6 tacos yields totalCost of 32.

#include <iostream>

using namespace std;

int main() {

  int numDrinks;

  int numTacos;

  int totalCost;

  cin >> numDrinks;

  cin >> numTacos;

  /* Your solution goes here */

  cout << "Total cost: " << totalCost << endl;

  return 0;

}

Design a C program the embed special character as leading and trailing to the input string and display the output.

Write C program to find sum of two numbers using #include Directives. Note: Use header file ADD.h in main program and call the function int sum(a,b).

Temperature Conversion:-

You are given the temperature T of an object in one of Celsius, Fahrenheit, and Kelvin scales.

Write a program to print T in all scales viz Celsius, Fahrenheit, and Kelvin.

Formula to convert from Fahrenheit F to Celsius C is C = (F - 32) * 5 / 9.

Formula to convert from Kelvin K to Celsius C is C = K - 273.

Here "C", "F", "K" represent that the temperature scale is in Celsius, Fahrenheit and Kelvin scales respectively.

The input contains the temperature (a number) and the unit of the temperature scale (C, F, K) without any space.

The output contains temperature in Celsius, Fahrenheit and Kelvin scales in each line in the format similar to input and the value of the temperature is rounded to 2 decimal places.

Q1.You are required to write a computer program that accepts a decimal number and generates a corresponding binary, octal, and hexadecimal output.

Q2. Write a program that accepts binary input string and generates corresponding octal and hexadecimal outputs respectively.
