非常简单的C编程题 高手来看下

1.#include<stdio.h>void main(){ int i,j,m,sum=0;for(j=1;j<=5;j++) { m=1;for( i=j;i>0;i--) m*=i;sum+=m;printf("%d!+",j);} printf("\b=%d\n",sum);}2.#include<stdio.h>void main(){ int i,j;scanf("%d",&i);printf("%d=",i);for(j=2;j<=i;j++) if(i%j==0) { i/=j;printf("%d",j);if(i!=1) printf("*");j=1;} printf("\n");} 收起
