इस ट्यूटोरियल में, हम एक साधारण कैलकुलेटर के लिए मेनू संचालित प्रोग्राम बनाने के लिए एक प्रोग्राम पर चर्चा करेंगे।
यह प्रोग्राम उपयोगकर्ता को निम्नलिखित गणितीय संक्रियाओं में से चुनने की क्षमता प्रदान करेगा - जोड़, घटाव, गुणा, भाग, एचसीएफ और एलसीएम।
उदाहरण
#include <bits/stdc++.h>
using namespace std;
//displaying 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";
}
//calculating and outputting result
void result(int choice, int a, int b){
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(){
int a = 5, b = 7;
int choice, res;
menu();
cout << "Enter your choice:\n";

cout << "Choice is " << choice << endl;

return 0;
} आउटपुट
Press 1 to calculate Sum of Numbers Press 2 to calculate Difference of Numbers Press 3 to calculate Product of numbers Press 4 to calculate Division of numbers Press 5 to calculate HCF of numbers Press 6 to calculate LCM of numbers Press 7 to exit Enter your choice: Choice is 1 Sum is 12
