Question

Please Help! how to make a program in c++ using switch statement.
Sample Run:
1 - Addition
2 - Subs
3 - Multiplication
4- Division
5 - Modulo Division
6- Average
7- Quit

Answer 1

cout<<"MENU OF OPERATION";
cout<<endl;
cout<<"1 - addition\n";
cout<<"2 - subtraction\n";
cout<<"3 - multiplication\n";
cout<<"4 - division\n";
cout<<"5 - Modulo Division\n";\
cout<<"6 - Average\n";
cout<<"7 - Quit\n";
cout<<endl;
cout<<endl;
cout<<"Enter your choice: ";
cin>> choice;

switch (choice)
{
case '1':
cout<<"***You Have Chosen Addition!***\n";
cout<<"Please Enter the first value:";
cin>>a;
cout<<"Please Enter the second value:";
cin>>b;
cout<<"Please Enter the third value:";
cin>>c;
cout<<endl;
Add = a + b + c;
cout<<"The sum of "<<a<<" and "<<b<< " and" <<c<< " is = "<<Add<<endl;break;
cout<<endl;
case '2':
cout<<"***You Have Chosen Subtruction!***\n";
cout<<"Please Enter the first value:";
cin>>a;
cout<<"Please Enter the second value:";
cin>>b;
cout<<"Please Enter the third value:";
cin>>c;
cout<<endl;
Sub = a - b - c;
cout<<"The Difference of "<<a<<" and "<<b<<" and " <<c<< " is = "<<Sub<<endl;break;
cout<<endl;

case '3':
cout<<"***You Have Chosen Multiplication!***\n";
cout<<"Please Enter the first value:";
cin>>a;
cout<<"Please Enter the second value:";
cin>>b;
cout<<"Please Enter the third value:";
cin>>c;
cout<<endl;
Multi = a * b *c;
cout<<"The product of "<<a<<" and "<<b<< "and" <<c<< " is = "<<Multi<<endl;break;
cout<<endl;
case '4':
cout<<"***You Have Chosen Division!***\n";
cout<<"Please Enter the first value:";
cin>>a;

cin>>b;
cout<<"Please Enter the third value:";
cin>>c;
cout<<endl;
Divi = a / b / c;
cout<<"The qoutient of "<<a<<" and "<<b<< " and " <<c<< " is = "<<Divi<<endl;break;
cout<<endl;
case '5':
cout<<"***You Have Chosen Modulo Division!***\n";
cout<<"Please Enter the first value:";
cin>>a;
cout<<"Please Enter the second value:";
cin>>b;
cout<<"Please Enter the third value:";
cin>>c;
cout<<endl;
Mod = a % b % c;
cout<<"The Remainder of " <<a<< " and " <<b<< " and " <<c<< " is = "<<Mod<<endl;break;
cout<<endl;
case '6':
cout<<"***You Have Chosen Average!***\n";
cout<<"Please Enter the first value:";
cin>>a;
cout<<"Please Enter the second value:";
cin>>b;
cout<<"Please Enter the third value:";
cin>>c;
Ave = a + b + c/3;
cout<<"The Average of " <<a<< " and " <<b<< " and " <<c<< " is = "<<Ave<<endl;break;
cout<<endl;
case '7':
cout<<"***You Have Chosen Quit!***\n";
cout<<"*****GOODBYE!!! PLEASE COME AGAIN!*****"<<endl;break;


default:
cout<<"INVALID CHOICE!\n";


}



system("pause");
return 0;

--- this is my sample program. but when i started diving 0 it prompted "Unhandled exception at 0x00041ee7 in Exercise1(switch).exe: 0xC0000094: Integer division by zero."/

Answer 2

dividing*

Answer 3

You can't divide anything by zero; you have to check operands before performing some operations; by the way, in the operation n° 6 (average) you wrote:
Ave = a + b + c/3;
That's a bad formula :-) ; you need brackets:
Ave = (a + b + c)/3;

Answer 4

How about adding if & else statement? is it possible?

Answer 5

within each "case" you can write any instruction set
