以下程序用于判断a、b、c能否构成三角形,若能,输出YES,否则输出NO。当给a、b、c输入三角形三条边长时,确定a、b、c能构成三角形的条件是需同时满足三个条件：a+b>c,a+c>b,b+c>a。请填空。 main() {float a,b,C； scanf("％f％f％f",&a,&b,&c)； if(【 】)printf("YES＼n")；／*a、b、C能构成三角形*／ else printf("NO＼n")；／*a、b、C不能构成三角形*／ }
有以下程序 #include main() {char c1,c2,c3,c4,c5,c6； scanf("％c％c％c％C",8az1,&z2,&c3,&c4)； c5=getchar()；c6：getchar()； putchar(c1)；putchar(c2)； printf("％c％c＼n",c5,c6)； } 程序运行后,若从键盘输入(从第l列开始) 123 45678 则输出结果是【 】。
