此BTC代码如何验证用户输入？

Question

我使用此代码获取用户输入并验证它，以增加用户钱包中的用户BTC。我需要一些代码的解释，它是如何工作的。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';
}

你的代码在任何情况下都不是一个API，而是一个代码，要注意诈骗者。你拥有的代码的工作方式和我将解释的一样，通过编辑和转换你的代码，以最小的形式让你更好地理解。

#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';
}
