以下程序的功能是求 3 个数的最小公倍数。请填空。 # include int max(int x,int y,int z) { if(x>y && x>z) return(x); else if(( )) return(y); else return(z); } int main() { int x1,x2,x3,i=1,j,x0; printf("Input 3 number : "); scanf("%d%d%",&x1,&x2,&x3); x0=max(x1,x2,x3); while(1) { j= x0 *i; if(( )) break; i=i+1; } printf("The is %d %d %d zuixiaogongbei is %d\n",x1,x2,x3,j); return(0); }
