Question

Problem 9: (20 Points) Write a CH program to implement sum, subtraction, multiplication and division operations of two numbers. Please use functions and switch statements. Please provide option to the user to continue the program after each operation. Please provide option to 'Exit' the program also

Answer 1

#include <iostream>

using namespace std;

float sum(float x, float y){

return x+y;

}

float subtract(float x, float y){

return x-y;

}

float multiply(float x, float y){

return x*y;

}

float divide(float x, float y){

return x/y;

}

int main() {

  

  while(true){

   cout << "Enter your choice: " << endl;

   cout << "1. Sum" << endl;

   cout << "2. Subtraction" << endl;

   cout << "3. Multiplication" << endl;

   cout << "4. Division" << endl;

   cout << "0. quit" << endl;

  

   int choice;

float x, y;

   cin >> choice;

   switch(choice){

   case 1:

   cout << "Enter 2 nubmers: " << endl;

   cin >> x >> y;

   cout << sum(x, y) << endl;

   break;

   case 2:

   cout << "Enter 2 nubmers: " << endl;

   cin >> x >> y;

   cout << subtract(x, y) << endl;

   break;

   case 3:

   cout << "Enter 2 nubmers: " << endl;

   cin >> x >> y;

   cout << multiply(x, y) << endl;

   break;

   case 4:

   cout << "Enter 2 nubmers: " << endl;

   cin >> x >> y;

   cout << divide(x, y) << endl;

   break;

   case 0:

   cout << "quit!" << endl;

   return 0;

   }

  }

  return 0;

}

} 8 } } main.cpp saved 1 #include <iostream> 2 using namespace std; 3 4 float sum( float x, float y){ 5 | return x+y; 6 7 float subtract(float x, float y){ 9 | return x-y; 10 11 12 float multiply(float x, float y){ 13 | | return x*y;| 14 15 16 float divide(float x, float y){ 17 return x/y; 18 19 20 int main() { 21 22 while(true) { 23 cout << "Enter your choice: << endl; 24 cout << "1.

30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 int choice; float x, y; cin >> choice; switch(choice) { case 1: cout << "Enter 2 nubmers: " << endl; cin >> X >> y; cout << sum(x, y) << endl; break; case 2: cout << "Enter 2 nubmers: << endl; cin >> X >> y; cout << subtract(x, y) << endl; break; case 3: cout << "Enter 2 nubmers: " << endl; cin >> X >> y; cout << multiply(x, y) << endl; break; case 4: cout << "Enter 2 nubmers: << endl; cin >> X >> y; cout « divide (x, y) « endl; break; case 0: cout << "quit!" << endl; return 0; } } return 0; }

Enter your choice: 1. Sum 2. Subtraction 3. Multiplication 4. Division 0. quit 1 Enter 2 nubmers: 2 4.5 6.5 Enter your choice: 1. Sum 2. Subtraction 3. Multiplication 4. Division 0. quit 2 Enter 2 nubmers: 3 1 2 Enter your choice: 1. Sum 2. Subtraction 3. Multiplication 4. Division 0. quit 3 Enter 2 nubmers: 1.1 2.2 2.42

Enter your choice: 1. Sum 2. Subtraction 3. Multiplication 4. Division 0. quit 4 Enter 2 nubmers: 2 4 0.5 Enter your choice: 1. Sum 2. Subtraction 3. Multiplication 4. Division 0. quit 0 quit!
