母牛生小牛的C语言算法

#include <stdio.h> int cows(int n)//求母牛的递归函数 { int i,count = 0; if (n < 4) return 1; else for (i = 1; i <= n - 3; i++) // 把新出生的小母牛代到递归函数里进行运算 count += cows (i); return count + 1; } void main() { printf("please iput the years: \n"); int m; scanf("%d",&m); printf("in the %d year,there will be the %d cows.\n",m,cows(m)); getchar(); }
