c++ - 此 BTC 代码如何验证用户输入？

Question

我有这个代码来获取用户输入并验证它以增加用户钱包中的用户 BTC。我需要解释一下这个代码是如何工作的。代码:

#include <iostream>
using namespace std;
int main()
{
    int btc_input, result_btc, btc_validation, btc_validation_1_input, btc_validation_2_input;
    result_btc = 0;
    btc_validation = 0;
    btc_validation_1_input = 0;
    btc_validation_2_input = 0;
    for (; btc_validation < 3; btc_validation++)
    {
     cout << "Enter the Value " << (btc_validation + 1) << " + " ;
     cin >> btc_input;
     cout << "Enter the Value " << (btc_validation + 1) << " + " ;
     cin >> btc_input;
     btc_validation_1_input == btc_validation + btc_input;
     cout << "Enter the Value " << (btc_validation_1_input + 1) << " + " ;
     cin >> btc_validation_2_input;
     result_btc = btc_validation_1_input + btc_validation_2_input;
     result_btc *= btc_validation_2_input;
     break;
    }
    cout << result_btc << '\n';
    cout << "Your BTC Wallet is Increased by " << result_btc << " coins " << '\n';
}

您的代码在任何情况下都不是 API，而是代码，请注意诈骗者。您拥有的代码的工作方式与我将通过以最小形式编辑和转换您的代码来解释的方式相同，以便您更好地理解。

#include <iostream>
using namespace std;

int main()
{
    int btc_input, result_btc, btc_validation;
    result_btc = 0;
    btc_validation = 0;
    for (; btc_validation < 3; btc_validation++)
    {
     cout << "Enter the number >> [" << btc_validation + 1 << "] " ;
     cin >> btc_input;
     result_btc += btc_input;
    }
    cout << (result_btc *= btc_input) << '\n';
    cout << "You entered " << result_btc << " numbers " << '\n';
}
