Hai vòng lặp while C++

C hỗ trợ lồng các vòng lặp trong C. Lồng các vòng lặp là tính năng trong C cho phép lặp các câu lệnh bên trong một vòng lặp khác. Hãy quan sát một ví dụ về vòng lặp lồng nhau trong C

Bất kỳ số lượng vòng lặp nào cũng có thể được xác định bên trong một vòng lặp khác, tôi. e. , không có giới hạn nào đối với việc xác định bất kỳ số lượng vòng lặp nào. Mức độ lồng nhau có thể được xác định tại n lần. Bạn có thể xác định bất kỳ loại vòng lặp nào bên trong một vòng lặp khác;

Cú pháp của Vòng lặp lồng nhau

Outer_loop và Inner_loop là các vòng lặp hợp lệ có thể là vòng lặp 'for', vòng lặp 'while' hoặc 'do-while'

Một vòng lặp lồng nhau có nghĩa là một câu lệnh lặp bên trong một câu lệnh vòng lặp khác. Đó là lý do tại sao các vòng lặp lồng nhau còn được gọi là “vòng lặp bên trong vòng lặp“. Chúng ta có thể xác định bất kỳ số vòng lặp nào bên trong một vòng lặp khác

1. Lồng nhau cho vòng lặp

Vòng lặp for lồng nhau đề cập đến bất kỳ loại vòng lặp nào được xác định bên trong vòng lặp 'for'. Dưới đây là sơ đồ luồng tương đương cho các vòng lặp 'for' lồng nhau

Vòng lặp lồng nhau trong C

cú pháp

for [ initialization; condition; increment ] {

   for [ initialization; condition; increment ] {
      
      // statement of inside loop
   }

   // statement of outer loop
}

Thí dụ. Chương trình bên dưới sử dụng vòng lặp for lồng nhau để in ma trận 3D 2x3x2

3. Vòng lặp làm trong khi lồng nhau

Vòng lặp do-while lồng nhau đề cập đến bất kỳ loại vòng lặp nào được xác định bên trong vòng lặp do-while. Dưới đây là sơ đồ luồng tương đương cho các vòng lặp 'do-while' lồng nhau

vòng lặp do while trong C

cú pháp

do{

   do{
      
      // statement of inside loop
   }while[condition];

   // statement of outer loop
}while[condition];

Ghi chú. Không có quy tắc nào mà một vòng lặp phải được lồng vào bên trong kiểu của chính nó. Trên thực tế, có thể có bất kỳ loại vòng lặp nào được lồng vào bất kỳ loại nào và ở bất kỳ cấp độ nào.

cú pháp

do{

   while[condition] {
      
      for [ initialization; condition; increment ] {
      
         // statement of inside for loop
      }

      // statement of inside while loop
   }

   // statement of outer do-while loop
}while[condition];

Thí dụ. Chương trình dưới đây sử dụng vòng lặp for lồng nhau để in tất cả các thừa số nguyên tố của một số.

Trong chương trình trên, vòng lặp đầu tiên sẽ lặp từ 0 đến 5 nhưng ở đây nếu tôi bằng 3 thì nó sẽ bị ngắt và sẽ không in * như trong kết quả.  

Tiếp tục Bên trong các vòng lặp lồng nhau

Bất cứ khi nào chúng ta sử dụng câu lệnh continue bên trong các vòng lặp lồng nhau, nó chỉ bỏ qua bước lặp của vòng lặp trong cùng. Vòng lặp bên ngoài vẫn không bị ảnh hưởng

Việc thực hiện vòng lặp bên trong tiếp tục cho đến khi điều kiện được mô tả trong vòng lặp bên trong được thỏa mãn.

Bạn có thể thêm vòng lặp while vào vòng lặp while không?

Vòng lặp chứa vòng lặp bên trong vòng lặp được gọi là vòng lặp lồng nhau. Nó có thể chứa vòng lặp for bên trong vòng lặp for hoặc vòng lặp while bên trong vòng lặp while . Cũng có thể vòng lặp while có thể chứa vòng lặp for và ngược lại.
