Question

Intreductien: This assignment helps you to reinforce the topics discussed in the class including a) Variables and data types, constants, arithmetic operations b) Data input and output Important: This is an individual assignment. Please do not collaborate. Crading policy: We will check a) The correctness of your program/solution b) Variable naming (self describing), using constants appropriately c) Appropriate commenting and Indentation Part I [11 points I. 4 Peints] Sound eravels through air as a result of collision betwoen the molecules in the air The temperature of the air affects the speed of the molecules, which in turn affects the speed of sound. The velocity of sound in dry air can be approximaned by the Sormula Velocity-3313+061,Tc Where Te is the temperabure of air in degree Celsius and velocity is meters second Write a program that allows the uscr to enter the air temperature and display the velocity at that temperature For example, if the temperature is O degrees the program should output At 0 degrees Celsius the velocity of sound is 331.3 m's Copy and Paste your program under comments in Assignemnt2xpp program 2. 12.5 Points) Arithmetic Operators and Operator precedence rules: Evaluate following 3+4.5 12 a 14.5 Points] Reading characters and strings from the keyboard 14.5 Points] Reading characters and strings from the keyboard: Consider the following c+ 3. program neludeciost .using nanespace stdi e. int main atring mystringl, myString?: 12. char mychari, sychara nyChar2 14 Coutcc"Bntera strings 16. ein>>tayStringl; //..", 17 18. einonyChar2 9 gecline(cin,mystring2)z 20 cin.get (eyChari) nystring return 25.

Answer 1

1.

#include <iostream>

using namespace std;

int main()
{
    double Tc,velocity;// Declaring variables
    cout<<"Enter the temperature: "; // Asking for user input
    cin>>Tc;
    velocity = 331.3+0.61*Tc;// Calculating velocity
    // Printing output
    cout<<"At "<<Tc<<" degrees Celcius the velocity of sound is "<<velocity<<" m/s.";
    

    return 0;
}

Enter the temperature: 0 t 0 degrees Celcius the velocity of sound is 331.3 m/s. ...Program finished with exit code 0 Press ENTER to exit console

2.

Expression	Result
3+4-5	=7-5 =2
4+4*3/6	=4+12/6 =4+2 =6
6+12*2-8	=6+24-8 =30-8 =22
6+12*(2-8)	=6+12*(-6) =6-72 =-66
(19-3)*(2+2)/4	=16*4/4 =64/4 =16

3.

cin>>myString1; would read single word till space.

cin.get(myChar1); would read character after "This" which is space here.

cin>>myChar2; would read single character 'i'

getline(cin,myString2); would read rest of the line.

myString1	myChar1	myChar2	myString2
This	single space	i	s my first C++ program
