The IP address space of a network is 201.1.5.0/24, which is divided by subnet, and the address mask is 255.255.255.248. Then, the maximum number of subnets and the maximum number of addresses that can be allocated for each subnet of the network are
The broadcast address for network 155.25. 0.0/20 is

Generally speaking, the higher the sound quality is required, the higher the quantization level and the lower the sampling frequency is.
The higher the sampling frequency, the closer the discrete digitized sound wave is to its original waveform.
Audio files in WAV format do not use compression algorithm, so they have good sound restorability, strong stereoscopic impression and relatively large file capacity.
MPEG video compression standards include MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21.
定义如下变量和数组: int k; int a[3][3]={1,2,3,4,5,6,7,8,9}; 则下面语句的输出结果是________。 for(k=0;k<3;k++) printf("%d ",a[k][2-k]);
下面程序的运行结果是________int main(){ int a[6],i; for(i=1;i3))%5; printf(“%2d”,a[i]); } return 0;}
定义如下的变量和数组int i;int y[2][3]={2,4,6,8,10,12}则下面语句输出结果for(i=0;i<2;i++)printf("%d ",y[1-i][i+1]);
以下程序段给数组所有的元素的输入数据,请选择正确的答案#includemain(){float x[5],m=0;while(m<5)scanf(“%.2f”,______);}
