问题：
以下程序运行时输_出到屏幕的结果第一行是 【17】 ,第二行是 【18】 。#includetypedef struct fact{ int m,z;}FACT;FACT fun1(FACT t1,FACT t2){FACT t3; t3.m=t1.m*t2.m ; t3.z=t1.z*t2.m+t2.z*t1.m; retum t3;}FACT fun2(FACT t){int m,n,k; m=t.m; n=t.z; while(k=m%n){ m=n;n=k; }t.m=t.m/n;t.z=t.z/n;return t;}void main(){FACT s,s1={8,4},s2={6,5}; s=fun1(sl,s2); printf("%d,%d\n",s.z,s.m); s=fun2(s); printf("%d,%d",s.z,s.m);}
