if语句在for或while循环中

我有循环谁不工作

它只显示第一个cout输入1个学生信息

或以太它跳过循环并在其下做所有事情

你能帮忙吗？

int x = 1;

    while (x <= 10) {
        ++x;
        if (x = 1) {
            cout << "enter 1 student info";
            cin >> name >> first >> second >> final>>id;
        } else if (x = 2) {
            cout << "enter 2 student info";
            cin >> name1 >> first1 >> second1 >> final1 >> id1;
        } else if (x = 3) {
            cout << "enter 3 student info";
            cin >> name2 >> first2 >> second2 >> final2 >> id2;
        } else if (x = 4) {
            cout << "enter 4 student info";
            cin >> name3 >> first3 >> second3 >> final3 >> id3;
        }
    }

...

   for (int x = 1; x <= 9; x++) {
            if (x = 1) {
                cout << "enter 1 student info";
                cin >> name >> first >> second >> final>>id;
            }
            if (x = 2) {
                cout << "enter 2 student info";
                cin >> name1 >> first1 >> second1 >> final1 >> id1;
            }
            if (x = 3) {
                cout << "enter 3 student info";
                cin >> name2 >> first2 >> second2 >> final2 >> id2;
            }
            if (x = 4) {
                cout << "enter 4 student info";
                cin >> name3 >> first3 >> second3 >> final3 >> id3;
            }
        }

我只是告诉你第一个错误,如果你在哪里使用=(赋值运算符)而不是==(等于运算符)

int x=1;

while (x<=10)
{++x;
    if(x==1)
