Declaración del problema: escriba un programa controlado por menús utilizando el caso Switch para calcular lo siguiente:
- Suma de dos números
- Diferencia entre dos números
- Producto de dos números
- División de dos números
- HCF de dos números
- MCM de dos números
Ejemplos:
Input: num1 = 5, num2 = 7, choice = 1 Output: Sum is 12 Input: num1 = 5, num2 = 7, choice = 5 Output: GCD is 1
Implementación:
CPP
// C++ program to illustrate
// Menu-Driven program using Switch-case
#include <bits/stdc++.h>
using namespace std;
// Function to display the menu
void menu()
{
cout << "Press 1 to calculate Sum of Numbers\n";
cout << "Press 2 to calculate Difference of Numbers\n";
cout << "Press 3 to calculate Product of numbers\n";
cout << "Press 4 to calculate Division of numbers\n";
cout << "Press 5 to calculate HCF of numbers\n";
cout << "Press 6 to calculate LCM of numbers\n";
cout << "Press 7 to exit\n";
}
// Function to calculate and display the result
void result(int choice, int a, int b)
{
// Display the result
switch (choice) {
case 1: {
cout << "Sum is " << (a + b) << "\n";
break;
}
case 2: {
cout << "Difference is " << (a - b) << "\n";
break;
}
case 3: {
cout << "Product is " << (a * b) << "\n";
break;
}
case 4: {
cout << "Division is " << (a / b) << "\n";
break;
}
case 5: {
cout << "GCD is " << __gcd(a, b) << "\n";
break;
}
case 6: {
cout << "LCM is "
<< ((a * b) / __gcd(a, b))
<< "\n";
break;
}
case 7: {
cout << "Thank you\n";
break;
}
default:
printf("Wrong Input\n");
}
}
int main()
{
// Get the two numbers
int a = 5, b = 7;
int choice, res;
// Display the menu
menu();
// Enter the choice
cout << "Enter your choice:\n";
choice = 1;
cout << "Choice is " << choice << endl;
// Display the result
// according to the choice
result(choice, a, b);
