Question

5. Write a program in C++ that will perform the operation of a simple CALCULATOR. But its output will be as shown in the output Screen-short. Three(3) Marks Guideline for developing the application. Input Output 1. Start program with asking The output will be question whether user is willing 1. The chosen Operator to continue or not. 2. Calculated result 2. If answer is Yes, Like:- System will ask for c\Users\Alamgir Documents\Visual Studio 2008 Proje. O choosing operator. ii. System will ask for Do you want to Start Calcuation (Y/y I N/n)? Y entering values. Wecone to CALCULATOR...... If answer is No Please choose your Operator(+,-.-.>? System will display "Good Bye...." Enter two Nunbers :29 7 message. You have chosen the Operator : Your calculation result -4.14286- X c\Users\Alamgir Documents\Visual Studio 2008\Pr o X Do you want to Start Calcuation (Y/y I N/n>? Good Bye.......
with the correct answer please

Answer 1

 #include <iostream> using namespace std; int main() { char option,sign;   int num1,num2; float result; // Loop forever (or till we hit the break statement)      do      {        result = 0.0;   cout << "Do you want to start the Calculator(Y/y : N/n)? :";      cin >> option;    if(option == 'n' || option == 'N')      {       cout<<"Good Bye...... !"; break;          } cout << "Welcome to the calculator......\n\n"; cout << "Please enter an operation (+, -, *, /)? : "; cin >> sign; if (sign != '+' && sign != '-' && sign != '*' && sign != '/')            {                       cout << "Unknown operator " << sign << '\n';                  continue;               }               else            {                cout << "Please enter a two numbers :"; cin >> num1>>num2;                   if (sign == '+')                        {                        result = num1+num2;                    }                       else if(sign == '-')                    {                               result = num1-num2;                     }                       else if(sign == '*')                    {                               result = num1*num2;                     }                       else if(sign == '/')                    {                        if(num2 == 0)                   {                              cout<<"Cannot divide by 0\n";                      continue;                       }                              result = (float)num1/ (float)num2;                      }               }               cout<<"\n\nYou have choosen the operator : "<<sign;                 printf("\nYour calculation result is : %f \n\n",result);                }while (1);      return (0); }
