编程：写两个函数,分别求两个整数的最大公约数和最小公倍数,用主函数调用两个函数并输出结果.

include "stdio。h"int gongyue(int a,int b);int gongbei(int a,int b);void main(){int a,b,temp,gy,gb;clrscr();printf("input two numbers please:");scanf("%d,%d",&a,&b);gy = gongyue(a,b);gb = gongbei(a,b);printf("最大公约数：%d\n",gy);printf("最小公倍数：%d\n",gb);getch();}int gongyue(int a,int b){ int temp; while(b!=0) { temp=a%b; a=b; b=temp; } return a;}int gongbei(int a,int b){ int num,num1,temp; num=a; num1=b; if(num >= num1) { temp=num; num=num1; num1=temp; } temp = gongyue(a,b); return (num*num1/temp);}不明白的发消息给我
