printf("volume is: %.2f\n",3.1415*r*r*h/3);
}
F. C语言初级测试题2
CBCACBDBB
12。函数f返回两个值的较小者，所以*r为7，选B
16。标准输出为B，A是标准输入，所以错了
G. c语言练习题
(int)a+b+c=((int)a)+b+c=(int)8.3+12.6-4.52=8+12.6-4.52=16.08
(int)(a+b)+c=(int)(8.3+12.6)-4.52=20-4.52=15.48
(int)(a+b+c)=(int)(8.3+12.6-4.52)=(int)16.38=16
H. c语言测试题目及答案
B.因为在计算1/2时参与运算的分子分母都是整型，将会得到整型数据0而不是浮点型数据0.5，而其他选项在做除法时，参与计算的分子或分母至少一方是float型，可以得到正确结果
