1、【新建工程】
2、【编写代码】#include <stdio.h>#include <stdlib.h>#include <stdarg.h>void main(int argc, char *argv[]) { char *strNumber=argv[1]; int a=atoi(strNumber); int flag=1; int i; for(i=2;i<a-1;i++){ if(a%i==0){ flag=0; break; } } if(flag==1){ printf("%d%s\n",a," is a prime"); }else{ printf("%d%s\n",a," is not a prime"); }}
3、【编译、链接】
