Question

Part E - Using 3 char variables, display the sum of 33, 35, and 37. Ask how to use "static_cast" in your cout
Part F - Show the night-time low temperature if the day-time high is 43 degrees F, and the spread is 50 degrees.
Part G - Display "Hello, World", using a string literal for Hello, and a string object for World.

test data:

The sum of 33, 35 and 37 is 105
The low temperature is -7 degrees.
Hello, World

This is C++ and use visual studio please.

Use blank lines to separate the major parts of your main function.

#include<iostream>
using namespace std;
int main(){

//Part A - The MPG (in whole numbers) of a car that can travel 400 miles on a 16 gallon fuel tank.
int mpg=400/16;
cout<<"400 miles using 16 gallons yields "<<mpg<<" MPG."<<endl;
//Part B - Total capacity of 3 theaters which hold 90 people each, and one that holds 150.
int theaters=3*90+120;
cout<<"Total theater capacity is: "<<theaters<<" people."<<endl;
//Part C - How far (in miles) to go to Mercury (56,974,146), then Saturn (849,221,795), then home (792,248,270)
long distance=56974146+849221795+792248270;
cout<<"Total distance: "<<distance<<endl;
//Part D - Using 3 char variables, display: ABC and A B C, and the 3 on 3 separate lines.
char a='A',b='B',c='C';
cout<<a<<b<<c<<endl;
cout<<a<<" "<<b<<" "<<c<<endl;
cout<<a<<endl<<b<<endl<<c<<endl;
//Part E - Using 3 char variables, display the sum of 33, 35, and 37. Ask how to use "static_cast" in your cout
char x=33;
char y=35;
char z=37;
cout<<"The sum of 33, 35 and 37 is "<<static_cast<int>(x+y+z)<<endl;
//Part F - Show the night-time low temperature if the day-time high is 43 degrees F, and the spread is 50 degrees.
int day_time_temp=43;
int spread=50;
cout<<"The low temperature is "<<day_time_temp-spread<<" degrees."<<endl;
//Part G - Display "Hello, World", using a string literal for Hello, and a string object for World.
string hello="Hello, ";
string world="World";
cout<<hello<<world<<endl;

}
