用c语言二维数组的赋值：打印杨辉三角，打印八行

以下是用 C 语言二维数组的赋值，打印杨辉三角，并打印八行的代码示例：

#include <stdio.h>

int main() {
    int rows = 8;
    int triangle[rows][rows];

    // initialize the first two rows with 1's
    triangle[0][0] = 1;
    triangle[1][0] = 1;
    triangle[1][1] = 1;

    // fill in the rest of the rows
    for (int i = 2; i < rows; i++) {
        triangle[i][0] = 1;
        for (int j = 1; j < i; j++) {
            triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j];
        }
        triangle[i][i] = 1;
    }

    // print the first eight rows
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j <= i; j++) {
            printf("%d ", triangle[i][j]);
        }
        printf("\n");
    }

    return 0;
}

输出结果如下：

1 
1 1 
1 2 1 
1 3 3 1 
1 4 6 4 1 
1 5 10 10 5 1 
1 6 15 20 15 6 1 
1 7 21 35 35 21 7 1
