Calculator That Takes Four Arithmetic Operations as Input

#include <iostream>
using namespace std;

int main() {
    int firstnum, secondnum;
    char arithmetic_operations;

    cout << "Enter first number: ";
    cin >> firstnum;

    cout << "Enter second number: ";
    cin >> secondnum;

    cout << "Enter Arithmetic Operations (+, -, *, /): ";
    cin >> arithmetic_operations;

    if (arithmetic_operations == '+')
        cout << firstnum << " + " << secondnum << " = " << firstnum + secondnum << endl;
    else if (arithmetic_operations == '-')
        cout << firstnum << " - " << secondnum << " = " << firstnum - secondnum << endl;
    else if (arithmetic_operations == '*')
        cout << firstnum << " * " << secondnum << " = " << firstnum * secondnum << endl;
    else if (arithmetic_operations == '/')
        cout << firstnum << " / " << secondnum << " = " << firstnum / secondnum << endl;
    else
        cout << "You typed an invalid arithmetic operations!\n";
