Question

Follow instructions to create a visual C++ project, add the CH code, compile, fun and fix errors, Write your Name, course, and date as comments on first line. Write Program's Name epp (Give it your last name with the assignment number as a name... Program0 LAST NAME). Explain what the program is to do along with any directions or instructions needed for program users (ie the purpose of each library included next to #include directive, names and uses of identifiers...etc). Name your identifiers appropriately. Configure the output terminal (the black window) so that the colors are: font is black and background is white. Again you need to submit the assignment as follows: 1. Submit softcopy of the assignment on blackboard on Thursday Oct 17. 2. Submit hard copy of the outputs and code in class on Friday Oct 18. Note: Before you print the code and output, make sure background color is white and text is black The Speed of Sound The following table shows the approximate speed of sound in air, water, and steel. Medium Air Water Steel Speed 1,100 feet per second 4,900 feet per second 16,400 feet per second Use if/else if to write a program that displays a menu allowing the user to select air, water, or steel. After the user has made a selection, he or she should be asked to enter the distance a sound wave will travel in the selected medium. The program will then display the amount of time it will take. (Round the answer to four decimal places.) Input Validation: Check that the user has selected one of the available choices from the menu. Do not accept distances less than 0.

Answer 1

#include <iostream>
using namespace std;
int main() {
int ch;
double speed,distance;
//reading the options
cout<<"Select the medium that sound is travelling through: ";
cout<<"\n1 Air\n2 Water\n3 Steel"<<endl;
cin>>ch;
//checking if ir is valid option
if(ch<1 || ch>3){
   cout<<"The menu value is invalid. Please run the program again.";
   return 0;
}
//reading distance
cout<<"Enter distance (in feet)"<<endl;
if(ch==1){
   cout<<"Air: ";
   speed=1100;
}
if(ch==2){
   cout<<"Water: ";
   speed=4900;
}
if(ch==3){
   cout<<"Steel: ";
   speed=16400;
}
cin>>distance;
//checking for valid distance
if(distance<0){
cout<<"The menu value is invalid. Please run the program again.";
   return 0;}
//printing time
cout<<"Traveled for "<<distance/speed<<" seconds";
}
