Answer:

The complete program is as follows:

m_str = input('Input m: ')

mass = float(m_str)

e = mass * 300000000**2

print("e = ",e)

Explanation:

This is an unchanged part of the program

m_str = input('Input m: ')

This converts m_str to float

mass = float(m_str)

This calculates the energy, e

e = mass * 300000000**2

This is an unchanged part of the program

print("e = ",e)

Write a program that asks the user for three names, then prints the names in reverse order.
sasho [114]

Answer:

The program written in C++ is as follows'

#include<iostream>

using namespace std;

int main()

{

string names[3];

cout<<"Please enter three names: "<<endl;

for (int i = 0; i< 3;i++)

{

cin>>names[i];

}

for (int i = 2; i>= 0;i--)

{

cout<<names[i]<<endl;

}

return 0;

}

Explanation:

This line declares an array for 3 elements

string names[3];

This line prompts user for three names

cout<<"Please enter three names: "<<endl;

This following iteration lets user input the three names

for (int i = 0; i< 3;i++)  {  cin>>names[i];  }

The following iteration prints the three names in reverse order

for (int i = 2; i>= 0;i--)  {  cout<<names[i]<<endl;  }

anotherFunc(myints);

Hence the answer is option d.
