c++ - 我如何在循环中再次设置变量

Question

我是 c++ 新手，对变量有疑问

int main() {
    int a;
    int b;
    int c;
    int e;
    int parafechar;
    int loop = 10;
    while(loop==10) {
        cout<< "Coloque a mensal 1\n";
        cin >> a;
        cout<< "Coloque a mensal 2\n";
        cin >> e;
        cout <<"Coloque a nota do cnem\n";
        cin >> b;
        cout << "Coloque a media dos trabalhos\n";
        cin >> c;
        if(a>b) {
            cout << "A media e : " << a*0.5 + b*0.25 + c*0.25<<endl;
        } else {
            cout << "A media e : " << e*0.5 + b*0.25 + c*0.25<<endl;
        }
        cout << "aperte uma tecla para fechar o programa\n";
        cin >> parafechar;
    }
    return 0;
}

在最后一行之后，我希望代码再次运行并再次设置所有变量，但程序无休止地运行，我该怎么办？(该程序是葡萄牙语，但它会计算成绩)感谢您的宝贵时间和帮助:)

Answer 1

after the last line i want the code to run again and all the variables to be set again but the program goes on endless, what should i do?

改变while中的检查，改变loop的值，使其最终满足条件停止循环。

while(loop > 0) {

   // Do your stuff...

   // Decrement loop. It will eventually become zero
   // and the conditional in the while statement will fail.
   --loop;
}
