if語句裏面for或while循環

Question

我是誰不工作

它只能顯示第一COUT進入1個學生信息

或醚它跳過循環，並盡一切下循環它

可以請你幫

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; 
      } 
     }

我剛纔告訴你的第一個錯的，如果在您使用=（賦值運算符），而不是==（等於運算符）

int x=1; 

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