Làm thế nào để bạn in A đến Z trong C bằng cách sử dụng DO WHER LOOP?

1. Logic Để in bảng chữ cái viết thường (A-Z) bằng cách sử dụng vòng lặp, chúng tôi khởi tạo biến ký tự ch thành a. Bảng chữ cái A có giá trị ASCII là 97. 97 được lưu trữ trong ch. Chúng tôi lặp qua vòng lặp trong khi giá trị của CH nhỏ hơn hoặc bằng z (tức là, giá trị ASCII của Z, là 122).
2. Làm cách nào để in các giá trị ASCII bằng bảng chữ cái?
3. Chương trình cho bảng chữ cái hiển thị bằng cách sử dụng cho vòng lặp.

Chúng tôi sẽ khai báo một biến bộ đếm của ch ch chat của vòng lặp và nó được khởi tạo bằng cách 65 65 (đối với trường hợp in trên) hoặc 97 97 (đối với chữ thường in) ;.
