第一种: 循环#include <stdio.h>#include <stdlib.h>int Fact1(int n){ int i=0,ret=1; for(i=1;i<=n;i++) ret*=i; return ret;}int main(int agrc,char*agrv[]){ int n=0; scanf("%d",&n); int ret1=Fact1(n); printf("%d\n",ret1); return 0;}第二种：递归#include <stdio.h>#include <stdlib.h>int Fact2(int m){ if (m<=1) return 1; else return m*Fact2(m-1);}int main(int agrc,char*agrv[]){ int m=0; scanf("%d",&m); int ret2=Fact2(m); printf("%d\n",ret2); return 0;}更多相关文章
