from the user, and prints the sum, product, difference, and quotient of the two

numbers.

Answer 1

#include <iostream>
using namespace std;

int main() {
    float n1, n2;
    cout<<"Enter n1: ";
    cin>> n1;
    
     if(!cin){                    // validation
        cout<<"Invalid input."<<endl;
        cin.clear();            // clears the error flag
        exit(1);
       }
   
    cout<<"Enter n2: ";
    cin>> n2;
     if(!cin){                    // validation
        cout<<"Invalid input."<<endl;
        cin.clear();            // clears the error flag
        exit(1);
       }    

    cout<<"SUM: "<<n1+n2<<endl;    
    cout<<"PRODOCT: "<<n1*n2<<endl;    
    if(n1>n2)
        cout<<"DIFFERENCE: "<<n1-n2<<endl;
    else
        cout<<"DIFFERENCE: "<<n2-n1<<endl;
    if(n2!=0)
        cout<<"QUOTIENT: "<<n1/n2<<endl;
        
    cout<<endl;    
    return 0;
}
