Find Force and Distance Using Switch Case Statement

The Switch case statement is a program which can be used as if/else statement. When sometime in a program we use repeatedly if/else statement so we can short replace programming code of switch/case statement. In a simple language we can say that switch case statement usually used to replace multiple use of if/else statement. A sample example is being given below.

 Switch (variable)

{

Case possible-value:

//code to execute

Break;

Default:

//code to execute

}

 

Question:

• Write a menu-driven program that calculates:

1. Force F=m*a 
2. Distance S=Vi*t+0.5*a*t*t 
3. Find x, x=(a+b)(a-b)

Source Code:

#include <iostream>

using namespace std;

int main()

{

            int a,b,m,f;

            cout<<"Choose an option \n1 - Calculate Force \n2 - Calculate Distance \n3 - Calculate x \n4 - Exit \n";

            cin>>a;

            switch (a)

            {

            case 1:

                        cout<<"Enter mass value";

                        cin>>m;

                        cout<<"Enter Acceleration";

                        cin>>b;

                        f=m*b;

                        cout<<" Force value is"<<f<<endl;

                        break;

            case 2:

                        int i,t,a,s;                                                                                                                  

                        cout<<"Enter Initial Velocity";

                        cin>>i;

                        cout<<"Enter time";

                        cin>>t;

                        cout<<"Enter Acceleration";

                        cin>>a;

                        s=i*t+0.5*a*t*t;

                        cout<<"Distance is"<<s<<endl;

                        break;

            case 3:

                        int x,o,b;

                        cout<<"Enter value a";

                        cin>>o;

                        cout<<"Enter value b";

                        cin>>b;

                        x=(o+b)*(o-b);

                        cout<<"X value is"<<x<<endl;

                        break;

            case 4:

                        cout<<"Exit\n";

                        break;

            }

}

Output:
