做出这个: @ @ @ @ @ @ @ @ @ ........ include<stdio.h>void main(){ int i,j,k,n; printf("一个正整数："); scanf("%d",&amp;n); if(n%2!=0) { for(j=1;j<=(n+1)/2;j++) { for(i=1;i<=(n+1)/2-j;i++) printf(" "); for(k=1;k<=2*j-1;k++) printf("$"); printf("\n"); } ...

#include<stdio.h>void main(){ int i,j; scanf("%d",&amp;j); for(i=2;j>=i;i++) { if(j%i==0) printf("和数"); else printf("质数"); break; }}为什么去掉break就不行了？
