Write a c++ program to implement the following . Assuming that a text file named first.txt contains some text written into it .write a function named vowelwords(), that reads the file first.txt and creates a new file named second.txt ,to contain only those words from the file first.txt which start the lowercase vowel (a,e,i,o,u).

For m = 6 and n = 5, write a C++ code to accomplish the above

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;
