杨辉三角 c语言输出10行

以下是输出杨辉三角前十行的C语言代码：

#include <stdio.h>

int main() {
    int rows = 10;
    int triangle[rows][rows];

    // Fill triangle with zeros
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < rows; j++) {
            triangle[i][j] = 0;
        }
    }

    // Fill in the first two columns with 1's
    for (int i = 0; i < rows; i++) {
        triangle[i][0] = 1;
        triangle[i][i] = 1;
    }

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

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

    return 0;
}
