杨辉三角n行+c语言程序

以下是一个可以输出杨辉三角前n行的C语言程序：

#include <stdio.h>

int main()
{
    int n, i, j, coef = 1;

    printf("Enter the number of rows: ");
    scanf("%d", &n);

    for (i = 0; i < n; i++)
    {
        for (j = 0; j <= i; j++)
        {
            if (j == 0 || i == 0)
                coef = 1;
            else
                coef = coef * (i - j + 1) / j;

            printf("%d ", coef);
        }
        printf("\n");
    }

    return 0;
}
