Khai báo mảng: Ví dụ 1 : Khai báo mảng 2 chiều int ia[5][10]; với int là kiểu mảng, ia là tên mảng, số phần tử mảng là 5 x 1...

<span style="color: mediumblue;"><strong>Khai báo mảng:</strong></span></div>
</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
<u>Ví dụ 1</u>:</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Khai báo mảng 2 chiều <strong>int ia[5][10]; </strong>với <strong>int </strong>là kiểu mảng, ia là tên mảng, số phần tử mảng là 5 x 10.</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
<strong><u>Ý nghĩa</u></strong>: Khai báo một mảng 2 chiều số nguyên gồm 50 phần tử, mỗi phần tử có kiểu int.</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Từ ví dụ 1, ta có cú pháp khai báo mảng đa chiều như sau:</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
tên_kiểu tên_biến[spt1][spt2]…[sptn];</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
<strong><u>Diễn giải</u></strong>:</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 72pt; margin-top: 10px; padding: 0px;">
-          tên_kiểu: kiểu dữ liệu muốn khai báo cho mảng</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 72pt; margin-top: 10px; padding: 0px;">
-          tên_biến: Tên của biến mảng, tên được đặt theo qui tắc đặt tên của C</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 72pt; margin-top: 10px; padding: 0px;">
-          spt1, spt2,…, sptn: số phần tương ứng của các chiều của mảng n chiều</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 72pt; margin-top: 10px; padding: 0px;">
<img alt="" src="http://tuhocanninhmang.com/images/array1.png" style="border: 0px; height: 152px; max-width: 100%; vertical-align: middle; width: 411px;" /></div>

<span style="color: mediumblue;"><strong>Tham chiếu đến từng phần tử mảng 2 chiều</strong></span></div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Sau khi mảng được khai báo, mỗi phần tử trong mảng 2 chiều đều có 2 chỉ số để tham chiếu, chỉ số hàng và chỉ số cột. Chỉ số hàng bắt đầu từ 0 đến số hàng – 1 và chỉ số cột bắt đầu từ 0 đến số cột – 1. Tham chiếu đến một phần tử trong mảng 2 chiều ia: ia[chỉ số hàng][chỉ số cột]</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
<img alt="" src="http://tuhocanninhmang.com/images/array2.png" style="border: 0px; height: 124px; max-width: 100%; vertical-align: middle; width: 438px;" /></div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
<span style="color: mediumblue;"><strong>Nhập dữ liệu cho mảng 2 chiều</strong></span></div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Mảng 2 chiều giống như một ma trận hai chiều, có kích thước bằng số dòng nhân số cột, để nhập dữ liệu cho các phần tử trong ma trận bạn cần duyệt qua từng phần tử trên từng hàng trong ma trận và đưa dữ liệu vào cho phần tử tương ứng như một biến thông thường</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
<u>Ví dụ 2:</u></div>
<pre>
for (int i = 0; i < 5; i++) //vòng for có giá trị i chạy từ 0 đến 4 cho dòng
//tương ứng với mỗi dòng sẽ duyệt qua từng phần tử trong mỗi dòng tương ứng
for (int j = 0; j < 10; j++) //vòng for có giá trị j chạy từ 0 đến 9 cho cột
{
printf("Nhap vao phan tu ia[%d][%d]: ", i + 1, j + 1);
scanf("%d", &ia[i][j]);
}
</pre>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
for (int i = 0; i < 5; i++) //vòng for có giá trị i chạy từ 0 đến 4 cho dòng</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 36pt; margin-top: 10px; padding: 0px;">
//tương ứng với mỗi dòng sẽ duyệt qua từng phần tử trong mỗi dòng tương ứng</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 36pt; margin-top: 10px; padding: 0px;">
for (int j = 0; j < 10; j++) //vòng for có giá trị j chạy từ 0 đến 9 cho cột</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 36pt; margin-top: 10px; padding: 0px;">
{</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 72pt; margin-top: 10px; padding: 0px;">
printf("Nhap vao phan tu ia[%d][%d]: ", i + 1, j + 1);</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 72pt; margin-top: 10px; padding: 0px;">
scanf("%d", &ia[i][j]);</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 36pt; margin-top: 10px; padding: 0px;">
}</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 36pt; margin-top: 10px; padding: 0px;">
@<u>Lưu ý:</u>Phép lấy địa chỉ đối với các phần tử mảng hai chiều chỉ có thể áp dụng khi các phần tử mảng hai chiều có kiểu nguyên, còn lại thì phép lấy địa chỉ cho các phần tử mảng nhiều chiều là không thực hiện được.</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-left: 36pt; margin-top: 10px; padding: 0px;">
Chúng ta sửa lại  ví dụ trên để có thể nhập được kiểu dữ liệu khác cho mảng hai chiều bằng cách dừng biến trung gian như sau:</div>
<div style="color: black; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">

Giải thuật đệ quy là giải thuật có chứa thao tác gọi đến chính nó. Giải thuật đệ quy cho phép mô tả một dãy lớn các thao tác bằng một số ít các thao tác trong đó có chứa thao tác gọi lại giải thuật (gọi đệ quy).</div>
<div style="background-color: white; font-family: Arial; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Giải thuật giải bài toán bằng đệ quy thường rất đẹp, gọn gàng, dễ hiểu, dễ sửa đổi. Tuy nhiên, việc xử lý giải thuật đệ quy lại thường gây khó khăn cho máy tính (tốn không gian nhớ và thời gian xử lý), hơn nữa không phải mọi ngôn ngữ lập trình đều cho phép mã hóa giải thuật đệ quy (ví dụ: FORTRAN) .</div>

Một chương trình viết trong ngôn ngữ C là một dãy các hàm, trong đó có một hàm chính (hàm main()). Hàm chia các bài toán lớn thành các công việc nhỏ hơn, giúp thực hiện những công việc lặp lại nào đó một cách nhanh chóng mà không phải viết lại đoạn chương trình. Thứ tự các hàm trong chương trình là bất kỳ, song chương trình bao giờ cũng đi thực hiện từ hàm main(). Trong C chương trình con chỉ tồn tại dới dạng hàm chứ không có thủ tục.</div>
<div style="background-color: white; font-family: Arial; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Hàm có thể xem là một đơn vị độc lập của chương trình. Các hàm có vai trò ngang nhau, vì vậy không có phép xây dựng một hàm bên trong các hàm khác.</div>

Xây dựng một hàm bao gồm: khai báo kiểu hàm, đặt tên hàm, khai báo các đối và đưa ra câu lệnh cần thiết để thực hiện yêu cầu đề ra cho hàm. Một hàm được viết theo mẫu sau:</div>

Các tham số dùng khi khai báo hàm được gọi là tham số hình thức. Các tham số được cung cấp cho hàm khi gọi hàm là tham số thực. Tham số thực có thể là một biểu thức, trong khi tham số hình thức thì không thể là 1 biểu thức. Dãy các tham số thực phải tương ứng về kiểu với tham số hình thức.</div>

Khi gặp một lời gọi hàm thì nó sẽ bắt đầu được thực hiện. Nói cách khác, khi máy gặp lời gọi hàm ở một vị trí nào đó trong chương trình, máy sẽ tạm dời chỗ đó và chuyển đến hàm tương ứng. Quá trình đó diễn ra theo trình tự sau:</div>
<div style="background-color: white; font-family: Arial; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">

<div style="background-color: white; font-family: Arial; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">

<div style="background-color: white; font-family: Arial; font-size: 13px; line-height: 20px; margin-bottom: 10px; margin-top: 10px; padding: 0px;">
Nếu trở về từ một câu lệnh return có chứa biểu thức thì giá trị của biểu thức được gán cho hàm. Giá trị của hàm sẽ được sử dụng trong các biểu thức chứa nó.</div>
